      Yes its more or less set up like the pdf describes.
      Everything works excellent when i dont redirect the gateway, i can reach the internet (not through tunnel) and the remote subnet without any problems. Even when i do redirect gateway i can reach the remote subnet but not the internet at all.

        Hum….

        If you do an ipconfig /all does it show that the gateway has been added to your client computer when you are connnected?

        Are you pushing more then just the gateway?
        If so are you adding the ; between items?

        push "dhcp-option DNS 10.0.0.10";push "dhcp-option WINS 10.0.0.10"

        Do the other pushed items show in ipconfig /all (wins or DNS if you are pushing them)

        Are you pushing the dns?
        You may need this to get to the outside world

        Just a few ideas

          The gateway gets pushed to the client correctly so that works ok.
          I don push any other options except the gateway, but im thinking that shouldnt matter cause im not trying to ping a dnsadress just a regular ip.
          Running out of ideas here :/

            what you are trying to do is working for me right now.
            i use TCP since i have to use a proxy.

            here's my config.
            maybe you want to compare it with your own.

            $ less /var/etc/openvpn_server0.conf
            writepid /var/run/openvpn_server0.pid
            #user nobody
            #group nobody
            daemon
            keepalive 10 60
            ping-timer-rem
            persist-tun
            persist-key
            dev tun
            proto tcp-server
            cipher BF-CBC
            client-to-client
            server 172.17.103.0 255.255.255.0
            client-config-dir /var/etc/openvpn_csc
            lport 443
            ca /var/etc/openvpn_server0.ca
            cert /var/etc/openvpn_server0.cert
            key /var/etc/openvpn_server0.key
            dh /var/etc/openvpn_server0.dh
            comp-lzo
            persist-remote-ip
            float
            push "redirect-gateway def1"
            push "dhcp-option DNS 172.17.103.1"

            We do what we must, because we can.

              Thanks, very helpful!
              OK i compared our configs now and its almost identical except subnets, port, cipher and compression. And those shouldnt matter much i guess.
              Did you add any rules to your firewall to get it to work ?

                  If you are connecting with windows xp service pack 2 make sure the firewall is off on the OVPN adapter.
                  You can have the firewall on all connections but the Open VPN.

                  There is a known issue with xp2 and openvpn.

                      I realize this topic is a month old, but a friend and I have been banging our heads again the wall for about 3 hours now trying to figure this out. We finally did. What you need to do is go into Firewall/NAT/Outbound then enable Advanced outbound NAT and add a line for your VPN's network much like your internal LAN. Once that was added it started working.
