https://live.paloaltonetworks.com/t5/general-topics/some-bfd-through-the-firewall-not-forwarding/m-p/165511#M53188 <P>I have multihop BFD session between two zones through a&nbsp;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.&nbsp;</P> Mon, 10 Jul 2017 15:19:03 GMT LCMember2963 2017-07-10T15:19:03Z https://live.paloaltonetworks.com/t5/general-topics/some-bfd-through-the-firewall-not-forwarding/m-p/165511#M53188 <P>I have multihop BFD session between two zones through a&nbsp;7050 firewall.

If yes please attach them here.</P><P>If you have a TAC case please give me the number. I can help take a look.</P><P>&nbsp;</P> Tue, 11 Jul 2017 02:07:30 GMT https://live.paloaltonetworks.com/t5/general-topics/some-bfd-through-the-firewall-not-forwarding/m-p/165713#M53218 abjain 2017-07-11T02:07:30Z
