Description

IPv6 TCP traffic passed in by a rule specifying route-to on the ingress interface doesn't get a state created on the egress interface.

To replicate, just edit the default LAN rule for IPv6 and specify a gateway. All TCP traffic from LAN will stop working. The SYN leaves correctly, SYN ACK comes back and gets blocked because of the missing state.

Fixed. There was a bug in FreeBSD that makes pf_test_rule() skip the state creation in this situation.

Yep, definitely fixed. I upgraded my edge firewall and put my v6 policy routing back and it's all working again.
