Problem with internal routing after 2.3 upgrade

  • Hello,

    I have few LANs connected through MPLS VPN (provided by a WAN operator) to my main site LAN.
    Each VPN have its own router.
    My default gateway is a PFsense 2.2 and all works correctly.
    The PF has a route for each MPLS router.

    –-------------------------------------------------- LAN
      |          |            |            |            |
      PF      MPLS1  MPLS2    MPLS3    MPLS4...

    But since I upgraded to 2.3, all internal routing are unstable (Backup over network crashes, SSH connections crash after few seconds)....
    Even if I check "Bypass firewall rules for traffic on the same interface", I set Firewall optimization to be conservative.
    I have to say I cannot change the MPLS routers config.

    Any help would be appreciated :'(

    I don't know where I'm wrong

    Thanx a lot

    Do you see anything blocked in your firewall log? If so, what does it look like exactly?

    "Bypass firewall rules for traffic on the same interface" can't always determine the full set of rules needed to account for asymmetric routing. You might have to make your own rules.
