I installed an OpenVPN service on our server. The default setup worked right out of the box. However, I wanted to use a VPN client to perform offsite backups of the computers in our LAN (using the backuppc software). First I installed OpenVPN clients on all of the LAN computers to be backed up, but OpenVPN on MacOS X seems to be a bit unreliable. Therefore I wanted to setup the VPN server to forward requests to our LAN network. The following changes were necessary:
push "route 192.168.0.0 255.255.255.0"push "route 192.168.0.0 255.255.255.0"
server:/etc/openvpn # echo 1 > /proc/sys/net/ipv4/ip_forwardOne can manually edit the /etc/sysconfig/SuSEfirewall2 file to make it work. I tried with the following changes (but I don't know whether they are all necessary):
server:/etc/openvpn # iptables -A INPUT -i tun+ -j ACCEPT
server:/etc/openvpn # iptables -A FORWARD -i tun+ -j ACCEPT
route add 10.8.0.0/24 192.168.0.2
