Help - Bi-Directional VPN using two Asus Routers in TUN mode
Posted: Sun Nov 10, 2019 7:44 pm
Problem - I can't access resources from the client to server or server to client. It says connected on the server but I am getting no access. I can confirm that a pihole device that I have works from the server network to the client network but I can't access the web interface or ping any devices from any location.
Information -
Server router - RT-N66W
Stock firmware
192.168.3.x
Client router RT-AC68U
Asus Merlin
192.168.2.x
What I have tried -
1. server router> vpn>advanced settings for OpenVPN>Manage Client-Specific Options (enabled) & client-client traffice (enabled) - Failed - It allowed me to ping the server network from the client router but only from the Network tools in the client router. I still can't ping any devices from the computer that is connected to the client network.
2. server router> vpn>advanced settings for OpenVPN>Custom Configuration>added a line of code [oconf=]route "192.168.2.0 255.255.255.0"[/oconf] and added [oconf=]push "route 192.168.2.0 255.255.255.0"[/oconf] - failed - still couldn't ping out from the computer on the client network.
3. Tried using the openvpn file that I got from the server router and using that on my android phone. - It works and I am able to access files from the server router network. (I am able to access the files from the computers that are connected to the server router through my android phone is I use the same openvpn file)
4. Tried using the open file that I got from the server router and used that on a laptop that was on the client network directly instead of the client router. - It works, I am able to ping and use RDP.
5. Ensured that both router's firewalls are down (atleast till I get this working)
More picture information that could help with context:
Logs from client router
What I have learned from testing - I can't specifically get any client computers on the client network to ping or access any client computers on the server network. However if I use the openvpn file directly on a device (client to server instead of server to server Tun type) like a phone or computer it will work.
Links I have looked at to try and help me but nothing has worked:

Any ideas or testing I can do to get this up?
