Some BFD through the firewall not forwarding

L1 Bithead

I have multihop BFD session between two zones through a 7050 firewall. Sessions originating from zone A to zone B work fine. Sessions originating from zone B to zone A do not work. Policies exist. There is a valid session in the session table with one way traffic. Log shows the traffic was allowed. This affects both IPv4 and IPv6 BFD peerings in the same way. I am running 8.0.3 code. This issue is not present if I downgrade to 7.1.X, but I have failover issues on that code so I'm not able to use it.

Are you able to perform a capture and packet-diag for the BFD packets from Zone B to Zone A? If yes please attach them here.

If you have a TAC case please give me the number. I can help take a look.
