wannabenerd78 I tried to setup openvpn to run a client (connecting to some vpn Provider via a TAP interface) and a server (providing connectivity over a TUN) interface on the same machine. Each configuration on it's own works fine. But as soon as I start the client config (connecting to the external Vpn Provider) I do not have any chance to connect to the device via VPN Please find the configuration files below: client -config : To connect to my external VPN Provider client dev tap proto udp local 192.168.2.X ; Cert ca /etc/openvpn/keys/ca.crt ns-cert-type server cipher BF-CBC #Blowfish ;Vpn server remote-random remote host.vpnprovider.com 1194 remote host.vpnprovider.com 1195 ;Auth auth-user-pass /etc/openvpn/credentials.sec persist-key persist-tun ; Logging comp-lzo verb 1 server- config : Allows me to connect to my box while I am on the road dev tun0 proto tcp-server ifconfig 10.9.8.1 10.9.8.2 local 192.168.2.38 port 1193 secret /etc/openvpn/static.key comp-lzo keepalive 10 60 ping-timer-rem persist-tun persist-key push "route 192.168.2.0 255.255.255.0" user nobody group nobody I guess it is kind of a routing problem.

Can anyone helpt me with this? Is it possbile to have such a setup at all? Do I need to setup my server with a TAN interface instead? Any help would be really apreciated.
janjust this is definitely a routing issue, but you may need an openvpn statement to fix it; your routing tables look a bit funny, please post the output of 'ip route show' for all 3 cases in a block.
