I= had set this to 1 to make sure the NAT64 traffic wasn't re-evaluated by ipfw so that I could still use the host IPv4 address locally (using a keep-state outgoing rule to avoid all the traffic being grabbed by the nat64 rule) how= ever with a bit of fiddling with the ruleset I can do this using tags with 'net.inet.ip.fw.nat64_direct_output=3D0'. It does look like there is still a regression (this worked on 12.2) but cou= ld be a pretty unusual case. --=20 You are receiving this mail because: You are the assignee for the bug.=
