Per /usr/src/linux/Documentation/Configure.help
--
  If you turn on IP forwarding, you will also get the rp_filter, which
  automatically rejects incoming packets if the routing table entry
  for their source address doesn't match the network interface they're
  arriving on. This has security advantages because it prevents the
  so-called IP spoofing, however it can pose problems if you use
  asymmetric routing (packets from you to a host take a different path
  than packets from that host to you) or if you operate a non-routing
  host which has several IP addresses on different interfaces. To turn
  rp_filter off use:

        echo 0 > /proc/sys/net/ipv4/conf/<device>/rp_filter
  or
        echo 0 > /proc/sys/net/ipv4/conf/all/rp_filter

  If unsure, say N here.

That sounds like its on by default though TrinityOS forces the
issue.
