      Hello,

      I'm trying to connect my Shrew Soft VPN client (v2.1.5 on Ubuntu Linux) to a pfsense firewall (v1.2.3). The client seems to make a tunnel, but there is no traffic passed. On the pfsense I 've got this errors:

      I can't find any solution on the internet for this error messages. Does somebody have a fix for this please?

      Kind regards,

      Burnout

        Ok, it seems that there is a VPN connection. (even with the errors in the log)

        But, I only can ping the pfsense box and my own assigned VPN ip. No other IP in the subnet behind the pfsense box is reachable. That sounds like a routing problem to me. Weird, because the routes seem ok.

        Has anybody an idea?

        (this problem is happening both on Linux and Windows)

          Is this pfSense box the gateway for things inside of the network? Did you add firewall rules to allow the traffic you want under Firewall > Rules on the IPsec tab?

          You can probably confirm via packet capture where the traffic is or is not going.

            Yeah, the pfsense is the gateway. Rules are set. :)

            I'll check out the traffic capture feature.

              My problem : tunnel is not mount.
              i don't understand why, cause have follow this tuto :
              http://doc.pfsense.org/index.php/IPsec_Road_Warrior/Mobile_Client_How-To
              What's your config ?

                Hello Neferites,

                I figured out the configuration isn't too hard. You can change multiple parameters (to "auto" for example) and it still will work. Can this be a firewall problem?

                My problem is that nothing 's routed to my VPN client from the network I'm connecting to. Altough the route tables are (or should be) correct.

                Kind regards,

                Burn

                  Hi,

                  I think my routes are correct cause ssh, and ping are ok.

                  But can't establish a tunnel between pfsense and my laptop.

                  Work on virtualbox, with this network :

                  192.168.1.2 <–----->192.168.1.1 eth1| 172.16.0.1 eth2 <---------->172.1.0.2 eth1 | 10.0.0.2 eth0 <-------> 10.0.0.1 WAN | 192.168.0.1 LAN <-------> 192.168.0.2
                  laptop                                  gateway                                                                gateway                                                      pfsense                                      computer on lan

                  i can ping laptop with computer on lan, connect with ssh on pfsense who use port forwarding to redirect on computer.

                  I try ipsec connection in agressive mode, with preshared key, using 3des and sha1.

                  But can't connect with ipsec...

                  An idea ?

                  Nef
