block drop in log quick on bge0 from <AUTOBLOCK> to any
block drop out log quick on bge0 from any to <AUTOBLOCK>

Am I misunderstanding pf?  I thought that that would block TCP, UDP,
ICMP and anything else trying to get through.

Since I started looking at this closer I did find that only some
connections have this problem.  Most get blocked as soon as the IP is
passed to the AUTOBLOCK table.
