So I'm setting up a new home network soon. I have my pfSense router, 1 16 port gigabit unmanaged switch and a 5 port unmanaged switch (will not need all ports, its just what I have), and 3 Engenius EAP1300 WAPs. I want to setup my network so that there are 2 networks. 1 for all home devices and 1 for IoT/guest but the IoT/guest will be WiFi only on a seperate SSID. The WAPs I have, have an option for it to be a guest network and setup its own DHCP server for the guest network but I want to have the pfSense router controlling everything and not the WAPs. I want the DHCP server and firewall rules going through the pfSense router. I was wondering how I could create a second subnet for the IoT/guest network and how to manage it all through the router. I would usually just do vlans but these are unmanaged switches. Am I asking too much and should I just go with the WAPs to do all the work?

Sorry for the title, didn't know what would be the best fit for this. I get right into my question: I have a VPN server listening on 10.145.30.2 (10.145.30.0/24) I have a Lab-Server listening ob 10.145.50.6 (10.145.50.0/24) I have my DNS (Domain Controllers) on 10.0.0.3 & 10.0.0.4. Both the VPN Server and the Lab Server can freely access the DNS and a nslookup works indefinitely fine (both NETs are allowed via Firewall). Now here is the mysterious problem: When my friend connects via VPN to my VPN-Net and gets a 10.145.30.x IP, then after some seconds his nslookup requests fail and the DNS server gets listed as UnKoWn instead of the actual dns-name. He does a nslookup to the LAB-Server. ---> All Traffic is passed through my net, once connected and authenticated via RADIUS. However the VPN-Server itself has no problems with DNS and nslookups at that time. If I change the Subnet (the VPN-Server can assign IPs from to the client) to the Lab Net (10.145.50.x) then everything works fine indefinitely . Just not with the VPN-Net. LAB Net is VLAN50 VPN is VLAN30 Apparently my firewall settings for the VPN Net are now identical with the ones from the LAB net. So I can rule out a FW issue here. Is there anything else I can check? Friends CMD (when connected to VPN): https://gitlab.com/openconnect/ocserv/uploads/c7d66e008050c4617afa340a29ac7ef5/image.png My CMD: https://gitlab.com/openconnect/ocserv/uploads/630a0bc305663821f700c055ab650d5a/image.png VPN-Server software used is ocserv on Debian. Works well except from the issue above. I already opened an issue at their gitlab but it got immediately closed stating it's a client issue... ocserv gitlab issue I created if that could be of any help: https://gitlab.com/openconnect/ocserv/-/issues/395

I am currently building a house and I've moved in with family for the time being. I want to keep our networks separate and I am running into some issues. I have 2 routers. Router 1 (R1), which is what is connected directly to the ISP, is working fine. I am trying to connect R2's WAN to R1's LAN, and here is what I currently have configured: Router 1 Gateway: 192.168.0.1 Subnet: 255.255.255.0 Set up static IP to R2 as: 192.168.0.253 --------------------------------- Router 2 I guess for some reason I thought that on the LAN TCP/IP settings that the IP (which is the 10.0.0.1) should have matched the first image of 192.168.1.1, but when I use this the router resets it to the 10.0.0.1 after I update it. With it being it's own network, I am keeping DHCP active on R2. Can someone tell me what I'm not doing properly here? I've also tried using a subnet of 255.255.255.128 on R2 without much success. I can connect to R2's admin page but it has no internet.

I'm trying to learn more about subnetting and came across the following which confused me. So, a Class A which is 255.0.0.0 or /8 can have 16,777,214 hosts and 0 subnets, at least that's what a chart I have shows. Yet, I've always known that Class A can have 127 networks. Am I confusing the terms subnet and network, as I always thought they meant the same as in dividing up the IP addresses into different networks/subnets? If they are actually different, then I'm really confused.

So, I am taking the Google "IT Tech Support" course on Coursera, and I am feeling a bit confused. They explained that in CIDR notation of a subnet (1952.168.1.0/5) the /5 denotes 5 available host IDs (or five 0s at the end of the mask), but looking things up outside of class, I am seeing more articles stating that the /5 would actually count the 1s in the mask, leaving 27 "0s" open for host IDs. Google - 192.168.1.0/5 = 30 possible hosts (25) = 32-2 Articles - 192.168.1.0/5 = 134,217,726 possible hosts (227) = 134,217,728-2 I want to believe the articles, as it makes more sense to my smooth brain, am I right or wrong?

Here's kinda where my knowledge is regarding internet/networks but I still don't understand everything enough to be confident. I know that the internet is split up into layers that are partitioned out for different uses and that my ISP ip isn't going to be my home devices IP since thats provided by my router. We probably have all seen 192.168.x.x but can you change those numbers completely? Can I change everything including the 192.168.x.x? If I change the 2nd to the last number from a 0 to 1, does that make a completely separate network in my home? I get ports are used as communication "doors" but I just don't understand why there are so many different ones (like gaming services or other communicating services) And last, Subnets. I don't understand what they are or what they do. I can watch a video on it but sometimes watching a technical video can make you go numb and find yourself reading emails when you should be listening or trying to understand. Also some of the classes I've purchased from some of the online classes, the teachers accent is so thick I have a hard time getting over that. That sounds bad but I'm being honest. I can't learn from them if I can't understand them. If anyone has any recommendations on classes, YT videos, sites, even paid classes. I would just like to understand this one step deeper. Thanks in advance. -
I just upgraded to a TP-Link ax3000 wireless router in order to have it host an openVPN server for my network. It's been quite successful. I have the VPN connection working perfectly where I can log in to my printers and router via the VPN, I can even remote desktop into my network computers. However, I can only access the computers via their IP address. They do not show up in windows explorer. I know that this has something to do with the fact that the router places the VPN on a separate subnet, but I'm not sure if it's an issue with Windows or the routing. (I already had to spend countless hours figuring out that Windows Defender doesn't like connections from other subnets) I already created a blanket policy to allow connections from the VPN's subnet, this enables me to access my smb shares by entering the host's IP address but if I try and use the host name I get nowhere. all computers involved are running Windows 10 Pro.

alright so in my home network I will be making a home server soon, the network config that I need is 2 cables between my NAS and my router for wlan transfers, 1 cable between my PC and my NAS for LAN transfers, and 1 cable between my PC and my router for internet access, how would I go about configuring my networking so that my pc would only transfer files between itself and the nas over the ethernet cable they (I plan on making them) share and not over the cables to my router? -
im using class C ip addresses in the devices of the network.all those devices are connected to switches and these switches are connected to 1 router (R1). R1 is then connects to another router R2 and R2 will be connected to several other routers such as R3,R4,R5 from other networks.i tried sending a ping request from a computer in the network which has the router R1 to a computer in the network that has the router R4. the request failed. then i connected a computer to R1 and tried to ping that from another computer which is connected to R1 through a switch the ping request failed. i think i havent configure R1 and its interfaces properly. this is what i have typed in the cli: Router> Router>enable Router#configure terminal Router(config)#hostname Router0 Router0(config)#interface gigabitEthernet 0/1 Router0(config-if)#ip address 192.168.0.40 255.255.255.192 Router0(config-if)#no shutdown Router0(config-if)#exit Router0(config)#interface gigabitEthernet 0/0 Router0(config-if)#ip address 192.168.1.41 255.255.255.192 Router0(config-if)#no shutdown Router0(config-if)#exit Router0(config)#exit Router0# note: im using cisco packet tracer any suggestions to fix this would be greatly helpful thank you. -
Hey guys, I'm trying to do a class assignment, where we're given a network address with a prefix, and we need to create a certain amount of subnets. The address I was given was 192.168.10.0/25, and I need to create 6 subnets. We're ignoring the "usable" subnet number for now (we don't subtract 2). I'm having trouble borrowing bits from the host portion for this, because if I wanted to create 8 subnets, I'd borrow 3 bits, making it 192.168.10.0/28. However, I only need 6 subnets. Would I just create 8 subnets and call for two to be unused, or is there something I'm missing, and I actually can make exactly 6 subnets? Thanks in advance.

Hey guys, as the title says I am running out of IP addresses on my network. Our DCHP server is ran by a windows 2012 R2 server, and we have a single domain and right now our subnet mask is 255.255.255.0 and our ip range on the scope we currently have set up is 192.168.0.30-245 (with 1-29 being static devices [like printers, sonic walls, etc], same with the numbers above 245). What would be the best way to increase the number of IP addresses we have? I've been trying to learn about changing the subnet masking and all that but I seem to be falling short on how it all....connects.

I'm new to this site and I've been having trouble finding the solution to my problem anywhere else. I live in an apartment that provides its resident free WiFi. In order to access the WiFi, you need a device's MAC address. This isn't a huge issue except with all my smart home devices. My other issue is that even with both my chromecast and Stadia controller connected to the WiFi, they aren't linked to each other. I figured that my own private network piggybacking off of the apartment's network would be the fix, and I do have ethernet access to connect a router, but I do not know what I'm supposed to do to create it. Any help would be much appreciated.

My wife has a small shop that she runs, and she will be adding a POS (Point of Sale) that requires it to be on a separate network. I realize there are probably a few different ways to do this, some being very expensive. Since it's just a small store with only the POS and one other PC, and maybe some cameras later, what's the more practical and affordable way to go about this? I thought about the Sonicwall TZ500, but $1300 to just separate the network seems a bit much. There has to be a more cost effective solution for a basic setup like hers that still complies with required polices. Any suggestions?

So my ISP is Spectrum and they have provided me with an Arris TG1682G as my router. I am a learning student and like to explore with networking and such so I decided to subnet my network and divide the wired and wireless. I purchased a TP-Link TL-ER5120 V2, Netgear GS724T, and a Netgear GS748TPS. The network is addressed as so: Arris TG1682G - 192.168.1.1, TP-Link - 192.168.0.1. I have a physical connection going from LAN1 on the Arris to the WAN port on the TP-Link. I then have a physical connection on LAN1 on the TP-Link connecting to the Netgear GS724T switch, from there I connect the two switches with another physical connection. So the TP-Link Router has a static IP route going to the 192.168.1.1 subnet so the wired clients can see the wireless. But now my issue is getting a static route to my TP-Link from the Arris. I cannot find out a way to do so on the GUI of the Arris Router and I've looked on other forums. No luck. Any suggestions will help! and yes I want to keep the network subnetted to that's not an option to get rid of.

I have a Huawei HG8245H Wireless Router, Optical Network Terminal. When i connect a computer to port one or two, it gives me a subnet mask of 255.255.255.0 and a local IP of 192.168.100.x but when i connect my computer to port three or four, it gives me a subnet mask of 255.255.254.0 and a local IP of 10.122.135.x I need help to configure my router to remove the barrier between ports 1 and 2 with ports 3 and 4, maybe due to VLAN.

Firstly, I'm not a networking expert. I'm trying to setup a radio connection between (2) PCs with directional data flow (see diagram). The PCs and radio modules have static IPs Is there a way to utilize an Ethernet switch to direct the flow of data to/from the radio modules? Any help here would be appreciated. Thanks

Could you theoretically connect 65.535 (255.255) devices on your home subnet network if you configured your router to have a subnet mask of /16 (255.255.0.0) and if not, why is this not possible? And if it is possible, to where could you stretch this limit. Thanks for your answers.

I am TERRIBLE with networking, please excuse my stupidity in advance. I have a router, PC and a phone. If my PC is connected to the router via ethernet, the PC's ip is 192.168.1.X If my PC is connected to the router via wifi, the PC's ip is 192.168.2.X My phone is always connected to the PC via wifi, so the ip is 192.168.2.X Now here is my issue, when my PC is connected via ethernet, my phone is not able to "talk" to my computer. How do I know this? I have a web server on my PC, set up on port 3000. When the pc and phone are on the same subnet (i am really not sure what to call it tbh, but im basically talking about the third digit in the ip), they can talk to each other normally, I can access the webpage on 192.168.2.66:3000 and I can even ping my pc. When pc and phone are on another subnet, I cannot access the webpage. What the hell am i trying to do? Basically I am a devlopper and I have an android mobile app that should be talking to the server that is obviously hosted on my pc. Can I force my computer to connect to the router via 192.168.2.X on ethernet? Or even better yet make my phone and ALL other devices connect via 192.168.1.X? I would prefer to the second option so that I can access my router login page that is on 192.168.1.1 and I cannot access that when my pc is connected via wifi and is on the 192.168.2.X subnet. Ask as many question as you want, I will happily answer. Please help? And thanks in advance P.S. I posted this on reddit and we had a huge discussion and could not find an answer to this problem Im not sure if it's against the rules to post a link to a reddit thread but I am going to cause there is a huge amount of data there (check the comments) that could help you help me with my problem, there are screenshots of my router's configurations and stuff

Hey everyone, So I'm trying to configure my network and wanted to change to a Class B Subnet (255.255.0.0). I've changed my subnet in the LAN section of my router but when I go into DHCP to change the start and end IP addresses from 192.168.0.1 to 192.168.255.255, it tells me that they are out of range. Correct me if I'm wrong, but aren't those IP's the range of a Class B subnet? My default gateway is 192.168.1.1 if that matters. Thanks for the help!

I have a TP-Link archer c2 wifi router behind an 8-Port auto configuring network switch. All devices on the 2 network switches and the modem/router are on the 192.168.0.1 subnet but the TP-Link router can only be on a subnet that is different so in this case 192.168.1.1. From my Desktop connected to the 8 Port switch I can ping the routers static IP on my main network as it has a static IP, but when I ping anything on the routers subnet e.g 192.168.1.2 some of the packets time out and the rest are >100ms. The only possible setting I could see that affects this is the routers NAT feature but enabling or disabling it hasn't helped. I tried to run tracert in CMD on my desktop to trace a device on the router but it timed out, devices on the router cannot detect network devices that aren't on the router and vice versa. Has anyone had this issue or does anyone know a solution to this issue? Diagram

Hello there, to make it short, I have a problem by setting up my new network correctly. First of all I tell you what I have, then what I want to do with it and then what is not working I attached a picture where you can see how my setup looks at the moment. What I want to do is to separate the two networks. So that all the systems which are connected to the router can not access the systems, which are connected to the switch. The switch itself is capable of clan, the router isn't. I already had the two networks separated with the help of the access point by just giving the AP a mixed IP in a different range than the DHCP on the router. But with the firmware update the capability of the AP where cut down so I just can use the DHCP-adress given from the router. Now my question. How do I need to configure the managed switch that I can share the internet connection From port "1" but have a separated network which isn't accessible from any other than the systems connected to the switch or the access point. If I just change all IP addresses to a different range I have the problem that I receive no internet connection. Any suggestions for this one? Thank you already for your help. Greetings from Germany, Insider47

Hi guys, What I mean by the title is that within a single IP range subset, i.e. 192.168.1.X, there are a certain number of IP addresses. 0-255. How would I then add something like 192.168.2.X to the same network, to where ALL the machines could see each other, so I have more IP addresses? I assume it involves subnet masks, but I don't know how to actually do this so it will work. Basically, say I have IP 192.168.1.67 and another machine on our network has IP 192.168.2.44. How can I make it so they see each other and I can utilize both ranges? Any help is appreciated. Thanks, Vitalius. -
I setup a very simple network using the internet from main router (10.10.96.1/19) connecting to WAN port on my own router (10.10.104.135/19). Inside my network, the router has IP 192.168.0.1/24 and my laptop has IP 192.168.0.2/24 (default gateway 192.168.0.1). What makes me confused is that I can ping from my laptop to an IP (let's say) 10.10.98.20/19(same subnet with the router). But I cannot ping from 10.10.98.20/19 to my laptop. I understand that I have to create a static route on big router (10.10.96.1/19) to make that host communicate with my laptop. But why can it reply the ping request from my laptop if it does not know the route?
