Hi. I cannot get a wireguard tunnel working on my dd-wrt router.

My setup is a DSL-632 with the WAN port connected to an ethernet port on my ADSL router (ASUS).

DSL-632 is set to autoconfigure DHCP. Without the wireguard tunnel enabled when I connect to the DSL-632 via WiFi I can see the internet fine.

When I enable the tunnel wireguard it connects - I can see from the log that I get bytes sent and recieved, but connected devices can't access the internet.

I can connect to the remote wireguard server from a client on a PC connected to the DSL-632 when the tunnel is disabled.

Obviously my end goal is to have any device connected to the DSL-632 be routed via the wireguard tunnel for anti-geoblocking reasons!

I'm assuming this is a routing issue? Any suggestions for a setting that might fix the issue?

Main LAN is on 192.168.20.X
ASUS gateway is 192.168.20.1
DSL-632 is taking 192.168.20.34 from DHCP via the WAN port
DSL-632 itself is currently 'stock' aside from the wireguard tunnel config - 192.168.1.1

Thanks for any hints.

Do you mean D-Link DIR-632?

I make no assumptions that you are on the current release for your router (currently 49392).

I presume you have read the applicable documentation.

WireGuard guides and documentation

Please post your applicable configuration information so that we can deduce what the problem could be. Thanks.

Yes, and latest firmware and setup PDF read.

I have it working now. In the end I deleted the configuration from the router and started again - and it worked second time around.

I had done the first setup by importing a wireguard config file. I think that had fouled it up.

Thank you for the reply.
