See subnets with OpenVpn/IpTables
 

Hi everyone,

I've just setup an OpenVPN server at my hosting company and I'm trying to tunnel all my LAN traffic through the server but I can't see the computers on the other subnet. OpenVPN is routed (tun)

Server Public IP : 91.121.19.??/255.255.255.0
Server VPN IP : 10.66.67.1/10.66.67.2 255.255.255.0

Lan Setup:

WRT54GL (OpenWRT) Router as OpenVPN Client:
- Public IP (my provider) : 88.163.41.??/255.255.255.0 gw 88.163.41.254
- LAN IP : 10.66.66.1/255.255.255.0
- VPN IP : 10.66.67.6/10.66.67.5 255.255.255.0 (automatically set)

Test computer:
- LAN IP : 10.66.66.11/255.255.255.0 gw 10.66.66.1


I successfully connect my client (the router) and the server with OpenVPN and I succesfully ping each other with their VPN IP addresses (10.66.67.X) but I can't reach the Server from the test computer and I can't ping the router LAN IP from the Server.

I suspect IPTable on the Router blocking some things but I can't see what is the problem

Could you please tell me which routes/gateways I should have on both sides and the IPTables rules on the OpenVPN Client (the router).

I'm completely lost. Thanks a lot for your help.
