PfSense 2.0.1 <-> Fritz!Box Fon WLAN 7270, IPsec

  • Hi!

    I've managed to set up an IPsec tunnel between a Fritz!Box and pfSense.
    After setting it up all was fine. For hours it worked. But now: the tunnel in question is shown as active on both sides: the Fritz!Box and pfSense. Trying to ping a printer on the other side fails. The printer is at sleep, but it answers to icmp echo requests.
    Vice versa the same: from a PC on the remote side I can't ping anything running and up localy. Really bad.

    After restarting pfSense and Fritz!Box it works again. Until the next line interruption by the provider.

    Within the logs I find on Fritz!Box and pfSense the same: only messages stating the connection is established. But no data crosses the wire!

    My setup is:
    PC1 ( <-> ( Fritz!Box (DSL)
      <-> Internet <->
      (fixed address) pfSense ( <-> ( PC2

    Routes on both PC are set to take Fritz!Box or pfSense as router for any subnet A default route is set for the local internet connection router:

    route: gw

    route: gw

    Now trying to ping from PC1 to PC2 or vice versa:

    PC2$ ping
    PING ( 56(84) bytes of data.
    –- ping statistics ---
    588 packets transmitted, 0 received, 100% packet loss, time 587008ms

    Any idea?
