  1. Remote Connection without Router Based DNS

    All “dynamic DNS” means is that you have a DNS record that is updated whenever your public IP changes. When it is built in to your router, it can notify the DNS provider every time it gets a new IP lease - but that is not the only way to make it work. Nearly all dynamic DNS providers provide software you can run on a computer that checks the public IP on an interval, say every 5 minutes, and updates the DNS record if it has changed. Some providers have an alternative - they make a special URL unique to your domain name that updates the IP to whatever host requests it every time it receives a request - this allows you to do something like make a cron job to wget the URL every 5 minutes.
  2. It sounds to me like you want a proper router, not an AP. The way you are using the Windows Hotspot is acting like a router. Try reseting the Totolink to default and use it in “Gateway” mode.
  3. Hotel Wifi

    What you are trying to do is most likely against the terms of service of the hotel’s network, which therefore isn’t encouraged by this forum.
  4. DIY modem/router/wifi

    When trying to do DIY networking you have to think about each piece separately - modem, router, and switching/wireless. You didn’t say what type of internet you have so I’ll answer the modem part of it for everything. There are no PCI/PCIe Coax modems. There are some for DSL (mostly the older types that don’t get above 15Mb/s). There are plenty of solutions for cellular modem connectivity. Assuming you have coax (DOCSIS) internet, your only option is an independant modem like a Motorola SurfBoard. For DIY routing you can use any old computer with at least two ethernet ports, or buy dedicated router computers (x86 embedded systems with often 4-6 ethernet ports), or buy dedicated routing hardware. For the first two options you would generally use an open source router operating system like PFSense, OPNSense, any many others, or you can start with almost any operating system and build up the router from scratch. A basic router only needs 3 things - the inside and outside interfaces, NAT to allow all your inside devices to use the single public IP (often implemented as a firewall rule in an SPI firewall), and a DHCP server. If using dedicated router hardware, from companies like Ubiquiti, Mikrotik, Cisco, and many others, then you will use whatever software it comes with. For switching, you can do it truly DIY by bridging multiple ports together, especially on the embedded router systems that have 4+ ethernet ports, but you will have higher latency (less than 1ms but still higher) than using dedicated switches that are designed for this purpose. For wireless you generally should expect to use separate APs rather than PCIe or USB wireless adaptors directly on your router, because the DIY operating systems like PFSense generally don’t have the best wireless support and features - but that doesn’t mean you can’t do it. An option for APs that doesn’t involve dedicated AP units is to take a regular wireless router and just turn off the DHCP server in it, and ignore the WAN port. Congratulations you now have an AP/switch. If you were looking to have an all-in-one unit, I recommend buying a premade wireless router from any number of vendors, and flashing it with an open source firmware like Tomato or LEDE (OpenWRT). This is an overall better value than putting together all the bits separately. But you’ll still need a separate modem.
  5. Hotel Wifi

    its not allowed on this forum to discuss circumventing systems, but I will clue you in to one thing - on nearly all systems, the bandwidth limiting is done based on the MAC address, so yes a second wireless adapter would have a separate bandwidth limit. The hard part is using both of those effectively, you won't be able to directly bond or team the two together.
  6. looking for a *very* specific vpn/proxy setup.

    you can control almost everything from the server side when a client connects, especially if you can run something like PFSense or OPNSense as your OpenVPN server, because they have easy client configuration exports that let you roll all your settings and the certificates into a single file. Unless you find something that is able to restrict endpoint's access to a particular process/port, you're going to have this issue no matter what. The proper way to handle this is to have a "DMZ" subnet where the OpenVPN server and the game servers exist, and with no access from that subnet out to your regular network. OpenVPN, like any good tool, doesn't have a target application. What you're thinking about is just the default server config that most installers include, as I said before. How? Where? You don't need to know anything about the client's home network - just choose an unlikely-to-conflict subnet like (I just randomly picked numbers for the second and third octet) for your VPN and Game Server subnet, and then the only possible conflict is if one of the clients also happens to use that same subnet for something in their local network. This is good advice even if you use something other than OpenVPN.
  7. looking for a *very* specific vpn/proxy setup.

    I actually would suggest OpenVPN - you say you tried it, but clearly you didn't find the setting that controls what gets routed over the connection. Normally the OpenVPN server will have a setting that it pushes to the clients called "RedirectGateway" - this means that the client changes its default gateway to go through the tunnel. You can either remove this setting on the server side, or on the client side you can use the command "Ignore RedirectGateway" https://community.openvpn.net/openvpn/wiki/IgnoreRedirectGateway After you've done this, you'll want to push a route to the clients that specifically sends traffic to your game server over the tunnel - if you want to route only a specific IP, then you use a /32 subnet. example: push "route" assuming that your game server is on The only conflict with their local network this will have is if they also have something on the network with the exact same IP address - in that case while they have the VPN connected, they won't be able to communicate with their local device using that IP because all traffic to that IP from their computer is going to go over the tunnel. TL;DR: OpenVPN on its own doesn't automatically forward all traffic over the connection, but the default server config for most installers does - you just have to edit the server config.
  8. Static IP or External Port Forwarding

    Can you put in or as the source IP? That normally means any IP
  9. The “Time Warner” that AT&T bought is not the same as the cable company that used to be called Time Warner. Time Warner Cable was bought in 2016 by Charter/Spectrum. What AT&T bought was purely the entertainment parts like HBO, CBS, the WB, etc. This doesn’t create a monopoly in the entertainment space, but when you look at what entertainment properties AT&T already owned it becomes clear they are trying to become a larger company in this area like Disney. The main issue or complaint with the AT&T/Time Warner merger is that they become both a content creation company and a content distribution company, and some fear they may do things like slow down content from other companies and other tricks to take advantage of their new position. By the way they also own Dish Networks.
  10. Time Warner entertainment and Time Warner Cable are separate entities. Time Warner Cable was purchased by Charter/Spectrum in 2016. What AT&T bought was just the entertainment, like CBS, WB, and others (as shown in the image you included)
  11. Router speed confusion (433 or 100 Mbps??)

    For routers up to 450Mbps per wireless radio it is common to see only 100Mbps ports. This is because unless you are right next to the router with a device with a good antenna (a laptop, not a phone) you won’t get a wireless link speed that is anywhere near the maximum - and even if you were right on top of it I wouldn’t expect the link speed to be greater than 300Mbps. So for most situations the wireless speed available will be less than the 100Mbps ethernet anyway. The second reason is that wireless is half duplex, meaning that if the link speed is 200Mbps, the max bandwidth in either direction is 100Mbps (this isn’t exactly true, the wifi protocol doesn’t force the speed to be cut in half, but in practice its hard to get much more than half the link rate in a transfer). The third reason is that low end routers with 100Mbps ports normally have a weak CPU in them that can’t handle more than 100-200Mbps anyway. Now technically this only affects the internet traffic, not any of your LAN transfers (except that anything going between the wired and wireless will go though the CPU).
  12. Amazon Alexas using bandwidth?

    For most people I would say that adding some extra smart home devices isn’t going to have a noticable impact on their internet connection, but with your upload being only 0.4Mbps then every device can have an impact - as well as any new software you install on your computer that may run in the background and do something. When you download, your computer has to send acknowledgement packets back to the source to confirm that packets are receieved correctly. If your upload is being heavily utilized (>90%) then it will start to affect the possible download speeds because the acknowledgements can’t be sent fast enough and cause delays in the next packets.
  13. Free or cheap DDNS service with own domain?

    So what company is the domain registered with now? In other words where do you have to go in order to add manual dns entries now?
  14. Free or cheap DDNS service with own domain?

    Who have you bought the domain from? Many like NameCheap have their own DDNS service builtin.
  15. Which wires are for 48v POE

    you should NOT directly inject 48V onto a line without the proper controller for Active POE. Passive POE should only be used up to 24V. The answer to your question is in the "Standards Implementation" (especially Power Devices) section of this page https://en.wikipedia.org/wiki/Power_over_Ethernet EDIT: Also the "Pinouts" section.
