I am looking to as cheaply and reliably setup home network. I am very novice at this stuff but can follow instructions well. We recently upgraded from crap verizon dsl to Verizon wireless lte home. They sent us a cellular modem/router. It keeps stopping every couple hours and we reboot to work a couple more rinse repeat. We called and are sending new unit. Hopefully that will work. There is also an xfinitywifi hotspot nearby that we can use but it is a weak signal. My laptop and kindle tablet can see it but cellphones don't from inside. I am looking for best solution to have an independent home router that is ethernet to verizon modem/router and wirelessly to xfinitywifi hotspot as either bond or failover as well as hopefully also have usb to connect external drive with plex media server to share video and music over home network. If I need more than one device to accomplish this that is fine but biggest issue is cost and second issue being cumbersome. But cumbersome is just inconvenient where cost is a big factor. Ps. I have more than one external drive so if I could use a USB hub to connect and share them all or a better solution would be great.

Good day LTT forum, I have a home network reliability problem and am trying to add some redundancy, and would like your advice on how good this plan seems (including input from those who have done something similar). Problem: My ISP, the only broadband provider to my house, is unreliable and has no incentive to improve their service. Due to my semi-remote location, LTE signal for at least cell phones (Verizon and T-Mobile towers tested) is weak. This impacts me because I work remotely and downtime is costly. I have asked every local ISP for wired and wireless options, and they either don't provide service, it's dialup-only, or they didn't even understand what I was looking for. Current Setup: I have an all-Ubiquiti network layout in my house (USG for the router, notable for having 2 WAN ports, an 8 port switch, and 2 wireless APs). Critical gear (work laptop, main desktop) is wired directly to the switch. All home users' cell phones are enabled to use wifi calling and can communicate effectively even if they get no signal. I have many reasons for not wanting to use a phone or a 'hotspot', both for performance reasons and the task of manually failing over each device to that new 'network' during an outage, along with pricing concerns (I am trying to keep monthly fees low and flexible). Proposed Solution: While searching for any possible way to essentially "add an antenna and a second connection" to my router, I came across this: https://unifi-lte.ui.com/ It's essentially exactly what I am looking for, an antenna that plugs into my network and acts as a secondary WAN. The pricing seems very reasonable for how much data I would use during an outage state (given numerous prior 'tests'). This solution uses AT&T LTE in the US, which claims to have 4G coverage for my location (not tested) Concerns: Location. My network closet is currently in the basement where LTE signal is the weakest. I'm guessing I would need to install a high-gain antenna or hope that AT&T LTE is coverage is solid. Connection: This wasn't clear from the instructions; would I plug this device into the second WAN port on my USG Router, or any available PoE port of the switch? Routing: If the answer to question 2 is "PoE port on switch", would I be correct in assuming that this device would do normal "router" tasks or work with the existing USG? Failover time: to anyone who has used this solution, how long does this failover time take? Do I have to take any manual actions? Questions: Do you all think that this is a good option? Has anyone else facing a similar concern used any alternatives as redundancy? Am I missing anything here? Thank you in advance!

I recently acquired a 5G mobile modem/router from my mobile phone provider, since my primary ISP has unreliable connectivity, wired both modems to an Ubiquiti Edgerouter-X 5, configured failover from primary to 5G, and wired that to my existing network. It works fine right now, but I wanted to know is it feasible to pair down the amount of NATing on my network? I know that mutli-NATed network *may* be susceptible to some connectivity issues when there is more than one router at play. So let me break down the different configured subnets: Primary Modem: 98.XXX.XXX.XXX/22 (modem only) 5G Modem/Router: 192.168.XXX.XXX/24 (different from below subnets) EdgeRouter-X: 192.168.100.1/24 (switch0 interface) Gryphon Router/AP: 192.168.1.1 (/24?), with device DHCP range: 192.168.1.100-249 I think this results in routes to/from the Primary modem being double NAT: Primary Modem (No NAT) -> ER-X (NAT) -> Gryphon (NAT) Is it advisable to remove the ER-X's Source NAT rule to Masquerade for the Primary Modem if my ER-X is only connected to the one Gryphon Router? Would this interfere with when a failover occurs that changes routes from Primary Modem to 5G? Then there's the routes to/from 5G modem/router that might be a triple NAT: 5G modem/router (NAT) -> ER-X (NAT) -> Gryphon (NAT) I know that there is no way to remove NAT from the 5G modem/router, but what about removing it from the ER-X? Would that work alright in a failover scenario? As for the Gryphon Router: It seems NAT is built-in and cannot be disabled. All I can configure is LAN IP, static & DHCP Ranges for devices, and configure WAN for DHCP, Static IP, or PPPoE. I know that the ideal solution would be to ditch Gryphon router+mesh alltogether, but I can't afford to replace it with an AP-only hardware, like a Ubiquiti AP. I would also like to avoid setting any additional manual IP addresses if possible, aside from switch0 interface. Lastly, is it possible for my ER-X to do traffic analysis of my Gryphon's subnet by changing ER-X or Gryphon config such as changing & broadening the ER-X's "switch0" interface's subnet, or does each router need to continue to have separate subnets? I think my ER-X config is relatively simple, but here it is sanitized below, and also my network diagram below that if you are curious what's downstream from the routers: Thanks for reading.

Hi, asking on the LTT forums because I couldn't find the answer on the Ubiquiti forums. This is in regards to their U-LTE technology, which is an LTE-failover modem, because Charter is extremely unreliable in my area. I am running an all-ubiquiti deployment, and have a U-LTE set up as a failover-solution. I have been experiencing brief but frequent ISP disconnects (or significant performance drops) over the past few months, which actually prompted me to purchase the U-LTE. This immediately resolved my problem, so well that the only way I know the problem is still going on is by seeing the data use going up in the U-LTE, or by calling my ISP and asking them if they see the issue on their side. What I don't see is the failover events in the unifi dashboard The weird thing is that I used to, or when it's a longer failover event, all the logs show up. I've double-checked the alerting settings and they should all be on. Does anyone know if there any way to get more verbose logging on the U-LTE? I want to know how often these events are happening and for what duration, so I can better contest with my ISP. Please let me know if there is other data I need to provide or other settings I should check. Thanks in advance

So My primary server went down recently and I've decided to just start from scratch with it after removing it from AD etc (it was the PDC) I have another server which is now functioning as the PDC and was a DNS/DHCP backup server using DHCP failover on the IPv4 scope. Is there anyway of now converting the failover scope on server2 to be a main scope? I can't go back to server1 to recover or transfer it or anything as the drive has been wiped, is there a way of just telling the DHCP service to turn the failover into a scope and take over?

Hi all, I am in the process of setting up 2x pfsense boxes for 2 sites. The sites both have there own internet connection and are currently connected via a VPN. My aim is to have the vpn link setup via the wan but also want to use the wifi link as a failover or another way for the sites to communicate. I had the wifi backbone setup as a static network and created a gateway so we could set it to do this but obviously i didn't think about how the networks either side would see each over. So really what im asking is how would be go about having a wifi link between the sites setup to where i can either route lan traffic across or have it go via the VPN setup via the wan interface or how i would set this up to failover if the internet at either site went off. Thanks in advanced and please note that im somewhat of a newbie pfsense. Kind Regards David

Hi everyone I'm an IT apprentice and got the task to find a solution for DNS failover. I know, that for windows at least, it's possible to set two DNS servers. One primary and one secondary and if the primary doesn't respond, it will switch automatically to the second one. Sadly not all clients in the company I'm working for are able to do that. So I'm searching for a solution on the DNS side. We have three Domain Controllers running DNS and Active Directory. The solution must be able to function internally without internet access, so external health checks are not an option. Please consider, that a possible solution must be higly available and reliable. Cost doesn't really matter in this case, so if additional hardware is needed, it's no problem as long as that is redundant. And again, it must be a server side solution. The Pictures included should visualize the infrastructure and the searched solution a bit. Is there a HSRP like solution, which uses a Virtual IP to which clients refer, and in the background health checks (like heartbeats) are checking the three DC's for connectivity and in an event of failure automatically switches the traffic? Or is there a way to do health checks within the Servers, so that the secondary monitors the connectivity of the primary and automatically "simulates" to be the primary in the event of a failure? EDIT If there is a solution without having to place some hardware in front of the DC's, but to handle the problem amogst the DNS servers themselves, such solutions would be preferred. EDIT END I know my text may be difficult to understand, but I'm open for questions. Thanks for the help in advance Johnny

What I am mainly looking to do is to share two different IP's (50ish Mbps Mediacom "Cable" and 12ish Mbps USA Communication "DSL") between two Businesses in an Internet Failover/Load Balancing system. One Business uses the 12mbps (minimum of 2 users on network, Max of 5ish on Network) and the other uses the 50mbps (Minimum of 2 users on network, Max of 4 on Network), but looking to have both will have the power to failover if the network goes down for one or for the other. I am not looking into internet Bonding in no shape or way, speed doesn't really matter, we could get by with 1mbps if needed. Internet is mainly used for POS, and Lookup of Products Secondly, the businesses are just right across the street from one another, so a PowerBeam like product will work to get internet to both side. (less than 300ft away) Lastly Possibly Voip for secondary line at 50Mbp recommendation? Here is what I think i need. 2 - Load Balancing Routers TP-Link Safestream 2 - Wireless senders and Receivers Ubiquiti PowerBeam I am not sure if Ubiquiti or anyone else has a product that can send 2 internet signals via one product TL;DR 2 IPS, 2 Different Locations, Failover internet, big antenna to shoot the signal over to one another hopefully I am on the right track

Hey guys! I've build a pfSense router about half a year ago. It worked fine... I mean it worked great. Never had an awesome experience like this before. Fast and secure with optional security features and packages. It left me down with a headache though since I've stepped up my game and implemented IPv6. My ISP assigns an 56 bit IPv6 prefix range upon request, I can chose between 56-64, they don't care :Þ Well, that didn't work out quite well since my ISP told me my router was receiving 64 bit prefixes, so I turned on IPv6 prefix size hint which solved that problem. I turned off "Block bogon networks" just to make sure. My problem now is: My router receives the correct 56 bit prefix and adds my own delegated 8 bit prefix to it to make it a valid 64 bit prefix. The LAN device has the correct prefix and it's own suffix but the wan doesn't It's getting even more weird though, the WAN gateway is a link-local address and does not have any connection at all. My ISP tells me their reservations system for IPv6 isn't on point yet because they're waiting for a firmware update from their hardware provider to fully support static/reserved IPv6 prefixes but that that's not causing the problem here since everything went OK in the transaction between the ISP's DHCP(v6) server and my router. Where did I go wrong? Second question: I've been thinking about purchasing parts to build a second router to use in a HA (High availability SYNC) and CARP (Failover) configuration. Both systems will have 3 NIC's (LAN, WAN and a dedicated syncronization NIC) but the problem is is that my ISP reserves my (static) IP to my WAN's MAC adress. For CARP I will have to use a Virtual IP to make both routers work on the same track take over when required. But that still doesn't solve the MAC bound situation. Even if I setup everything correctly my modem won't assign the static IP to my second router since the MAC isn't correct. Is there any way to spoof this MAC adress within CARP to fix this solution? Or is there another way around? Sorry for the long question, I've been slamming my head into the table for 3 months now (The time my ISP took to respond xD)
