>Description:
This is a multihomed machine. I expect replies to requests that came on one interface to leave the machine on the same interface. This doesn't happen.
>How-To-Repeat:
Assuming you have packets coming in through $local_if, and the following ruleset:

pass in quick on $local_if reply-to ($local_if $local_gw) \
        inet proto tcp from any to ($local_if) \
        port = 80 flags S/SA keep state

This rule does create state, but the packets leave the machine through the interface the default route is connected to, which is not $local_if.
