Hi. I'm setting up a VPN with openVPN on a debian lenny server. I successfully installed it in the server, then created the certificates and both client (winXP) and server config files. For the client I use openVPN gui. I tested the tunnel and everything went just fine. I even can ping the openVPN server from the XP client. But that´s all. I can't ping any machine behind the openvpn server. Some facts that you may find useful to help me with this issue are:

  • The openVPN server is not the default gateway of the LAN. The dg is a pfsense server
  • I don´t have iptables enabled (policy of all chains are ACCEPT).
  • I have configured ip forwarding (echo "1" >/proc/sys/net/ipv4/ip_forward)
  • I my server.conf I have the line: push route "192.168.1.0 255.255.255.0")
  • My openVPN server has two NIC's. One connected to the LAN, and the other to the WAN. I have checked and all seems to be OK. I think that the problem is connected with routing the traffic from the vpn to my LAN but I don't know how to do that (besides the push route line in the server.conf).

I Hope you can help me! Thanks!

If the gateway is not the default route, then every machine behind the server will need a route back.

On one of the machines to which you are trying to connect, create a route:

route add -net 10.207.40.0 netmask 255.255.255.0 gw 192.168.0.1 up

Where 10.207.40.0 is the OpenVPN subnet allocated by your OpenVPN server and 192.168.0.1 is the LAN address of your openvpn server.
