Hello, I am trying to configure the RUT240 as wireguard 'server' so other devices like PCs or smartphones can connect to LAN. The router is accessing the internet trought a SIM card.

The problem is that the devices apparently connect to the RUT240 but nothing is received (only transmitted). In the status tab for wireguard no peer connected is listed. I think is a firewall issue.

Can someone provide a backup config from the router with wireguard working? so i can modify it on my purpouse.

Thank you very much.

Hi,

Unfortunately, I can't give you a backup configuration, but I can give you screenshots of the working WireGuard configuration.

Here the main aspects are that we need IP address that is 10.0.0.1 on server side (RUT240).

And peer configuration:

Public Key of client-side (Android). Allowed IP must be the one from the client (Android): 10.0.0.2 and endpoint host WAN IP of Client (Android).

Android:

Address of the client: 10.0.0.2

Public key of the peer must be server-side (RUT240) public key. Allowed IP: 0.0.0.0/0 and endpoint of server-side (RUT240) WAN IP.

Hope this helps.

Thank you Ernestas,

Is necessary to add the Endpoint Host? I guess it is the public IP address, isn't it? My 'clients' don't have fixed ip address.

Do i have to add any config in the firewall?

If you don't have a fixed public IP, you can try dynamic DNS services which will give you a domain, which forwards to your current public IP.

Also, no firewall exceptions are needed, I just tested it and tunnel established on default factory settings.

Hello,

I've restored the RUT to factory. Configured SIM PIN, changed LAN IP, added Dynamic DNS, installed Wireguard from the package manager and configured it as u did but still no success. I attach some screenshots:

RUT240 'Server' config

RUT240 'Client' Config

Could you maybe try a different mobile phone? I can't see that being a problem in RUT240 as I successfully tested it and it works fine.

I changed the RUT240's SIM to other provider one. I tried to connected from a Windows PC with the same config as the Android phone but still no success. The client transmit but doesn't receive, in the RUT I can see that the handshake isn't done.

If you think that could be the firewall issue - you can try executing /etc/init.d/firewall stop in CLI

No way, i disabled de firewall (with several warnings) but there is no handsake. The peer transmits but never receives.

I cannot understand how I am not able to make , such a simple config protocol, work.

Please try factory resetting the router. If after that it still won't establish the connection - send me your troubleshoot file via private message.

Hello ErnestasB, I sent you a private message. I didn't have time to try to establish the wireguard connection for a while.

Recently, i tried reseting to factory as you suggested but still no success. Which files do you need me to send?

Thank you very much.
