OpenVPN routing issues

[eduroca]

Hi, I'm running an N66U with 378.55.

I have an OpenVPN server set up, but I'm having problem reaching a few clients withing the local network, when connecting via VPN.

In particular, I'm having problems reaching an Ubuntu server with the LAN. All connections to the server fail, and I can't even ping the server.

LAN connections made directly (ie: not through OpenVPN) work perfectly fine, as do connections made via WAN.

Most other devices work (Windows computers or iPhones/Android phones) seem to work fine, as far as I can tell the only devices that fail are UNIX based devices (Ubuntu server, a second router and network printer).

My guess is that there's some sort of routing issue. OpenVPN clients get a 10.8.0.0 subnet while the LAN is 192.168.x.x).

I was wondering if anyone had any ideas on how to fix this.

Check the firewall of those clients, make sure they accept connections with an IP of 10.8.0.0/24

These are the firewall rules on the server. As far as I can tell, packets should be passing through transparently.

Here's the firewall rules on Webmin (server is behind N66U).

Just to be sure, disable the firewall entirely on that ubuntu target. and run iptables-save to verify all rules are gone.

I did, no dice :/
