add "keep state", e.g.:

pass out quick proto tcp from any to any port = 80 keep state group 151

I'm not a real genius with this stuff--I am just modding what the
prev. admin had set up for our site (I need to read up on how the
groups work--that's the part I don't quite understand).  Anyway, you
can use netblock notation in rules, e.g.:
 pass out quick proto icmp from any to group 250

I would assume you can do blocks on "from" as well.  We don't specify
interfaces except in the default rule to block everything.  In the
"allow" rules, we use IP's.  We, too are using IPMP.
