      I have openvpn running on release 1.0 with no issues.

      Maybe try retyping the pool address and saving.
      Or
      Deleting the openvpn server and creating it again.

        OK I use 1.0 too. I noticed that I can't delete the default VPN tunnel, and when I edit it, enter details and save it creates a second VPN tunnel while leaving the default one (with empty fields, empty certificates, etc). Don't know if it's an issue, I remember having this same "bug" in RC2-3

        I changed the pool to another network then used 192.168.192.0/24 again but it didn't solve the problem.

        I deleted my VPN tunnel then recreated it. When I reconnected my client the logs showed that it was still getting the old VPN tunnel details (push, etc). I then rebooted pfsense and my new VPN tunnel didn't appear. I recreated the tunnel and rebooted pfsense again, and then the tunnel appeared. This is probably normal behavior though, maybe mentionning it here will help another newbie ;)

        I got the same result though, I can ping 192.168.192.1 and 192.168.1.253 (LAN interface) but no other IP.

        I see in the logs a route is added (route ADD 192.168.1.0 MASK 255.255.255.0 192.168.192.5) but I can't ping the 192.168.192.5 IP which, I take it, is a kind of virtual gateway attributed by pfsense (it also acts as DHCP server)?

        SFM > did you have to add any firewall rule that I didn't add (cf my original post) or anything else on pfsense?

          Peterclo,

          Did you get a chance to look at this …
          http://www.uplinksecurity.de/data/pfsense-ovpn.pdf

          It is very well written.

          I only have one rules in my firewall to opne 1194 to vpn clients.

          WAN RULE
          UDP  *  *  *  1194  *  OPEN VPN

            Absolutely, that's the tutorial I followed to set up my VPN, it's indeed very nice.

            Thank you for your answer regarding the firewall rules, I was wondering if I had forgotten something there.

            Do your clients also get a 255.255.255.252 netmask?

              Peterclo,

              Ok I just went and tryed my openVPN and I am having the same issues you are.

              I upgraded yesterday and I guess hadn't tryed it since then.

              It worked without any issues with RC3 and now that I am at 1.0 it does not work.

              I get connected but can't get anywhere, I also get the 255.255.255.252 mask.

              Either something needs to be changed when going from RC3 to 1.0 or there is an issue with 1.0.

              SFM

                You can't imagine how relieved I am. Well, no, not really, I'd prefer it if it worked :p I hope the issue can be resolved now that we're both having problems here.

                      cheers,

                      first off, i have 1.0 running for road warriors & site-to-site and both tunnels
                      work as supposed, so i don't think it's a pfsense problem.

                      Question, the LAN servers you want to ping, do they have the
                      pfsense as gateway? If you are testing and a second gateway
                      is available this could be the problem (i encountered that, because
                      i forgot to change the gateway of one of my LAN boxes).

                      On one of your LAN servers and road warrior please show me "netstat -r".

                      Also, please install a "any, any, any, …" testing-rule for both WAN and LAN
                      to ensure it is not the firewall.

                      Reboot the box once after that and try again.

                      Do your clients also get a 255.255.255.252 netmask?

                      yep, that's ok.

                        Hey dairaen!

                        He he, that was it, and as I thought it was just me being stupid: the computer I was trying to ping was using our current router as a gateway and not my precious new pfsense box :) No wonder the poor packets didn't know how to find things :)

                        Thanks a lot for your help and the great tutorial you wrote! Maybe you could add a "Beware of your gateway" line in the section where you're supposed to test your new VPN tunnel?

                        I hope SFM has the same happy ending :)

                          Dairaen,
                          thanks for helping me figure this out.

                          I was using the pfsense as gateway on lan server to answer that question.

                          What I was doing in previous versions is pushing the local network with Wins and Dns servers.
                          This worked without any issues.

                          When I upgraded to 1.0 this no longer worked…......

                          After putting the local network in the proper location in the vpn server config and deleting it as a push everything works.

                          It also worked if I added (push "redirect-gateway def1") and left my config as it was. Only proplem with this is I do not want clients using it as there default gateway.
