IPSEC connected but cannot ping remote network.



  • Hi all, I have 2 pfsense boxes both running the latest version. I have configured IPSEC on both boxes and they seem to connect OK:

    INFO: IPsec-SA established: ESP/Tunnel…

    The problem is once connected I try to ping (or open a RDP connection) to the remote network and the connection fails (fails in both directions). Subnet at one end is 192.168.0.0/24 and the other end is 192.168.4.0/24. At one stage ping was working for a few minutes but then stopped again. In my logs I am not getting any errors only a warning:

    WARNING: setsockopt(UDP_ENCAP_ESPINUDP_NON_IKE): Invalid argument

    any ideas on resolving this issue?

    Thanks.

    Scott.



  • Known issue with Racoon.  We are waiting for the new version to be released.

    Not sure of their release timeframe.



  • Is Racoon to blame for the warning as well as me not being able to communicate between the two subnets connected by the IPSEC? I have seen some people in the forums which have IPsec working OK?

    Thanks.



  • Not sure of the specifics.  IPSEC works fine for me as well, but there is something that triggers the bug.



  • OK, thanks for your help Sullrich. Guess I will just use PPTP for now.

    Regards,
    Scott.



  • Personally I would give OpenVPN a try over PPTP.
