      Hi All,

      I have OpenVPN server configured on a PFsense 2.0
      My RoadWarriors could connect and all is fine.. for a while…

      After a couple days/weeks (maybe a power outage?) things stop working.
      I can still connect ...
      (from todays log)
      trmVPN UDP:1194 Client connections
      Common Name Real Address Virtual Address Connected Since Bytes Sent Bytes Received
      peter 1xxxx:10089 10.20.20.6 Mon Dec 12 10:35:13 2011 18419 18454

      But that's it, I am not seeing anything beyond this point.
      Not able to connect to the fileserver that sits behind the pfSense...

      Cannot ping the pfSense box - or any other server behind the firewall... from the client

      The firewall rule " allow all " inserted by the OpenVPN wizard is still there ...

      A pfSense reboot does not help.
      Turning the OpenVPN server off/on does not help.
      dis/enable the "allow all" rule does not help.

      I can connect - so it is not a certificate expiry issue...

      On the client I see
      Destination    Gateway        Genmask        Flags Metric Ref    Use Iface
      10.20.20.1      10.20.20.5      255.255.255.255 UGH  0      0        0 tun0
      10.20.20.5      *              255.255.255.255 UH    0      0        0 tun0
      192.168.20.0    10.20.20.5      255.255.255.0  UG    0      0        0 tun0

      But again I cannot pint anything in 192.168.20.0/24 were I could ping everything couple days ago.

      So something is tampering this OpenVPN setup. (A reboot?)
      Last time I deleted everything from the pfSense - re-did certificates, OpenVPN server, redistributed keys to clients and all was good... for couple weeks...

      What the heck is going on?
      Where do I start looking for things?

      Thanks

      Peter

        How stupid is this one…

        One of the unused NICs had the same CIDR/24 as the tunnel network...

        Changed the tunnel network and all is fine...

        Still weird that this worked for a few days/weeks ...

        Anyway solved it leave it here for others to find...

        Damn'it

        Peter
