I too noticed this problem with 1.3 a while back and reverted to 1.2.
Unfortunately I haven't yet had the chance to run up a test firewall and
double-check things.

I had the rules initially on OPT1, as per my 1.2 config, upgraded to 1.3
and everything appeared OK.  I think I then rebooted the machine and
everything on OPT1 stopped working so I migrated all of the rules to the
WAN interface and it started working again!  And then for some reason it
flipped back so I had to migrate the rules back to OPT1!

I also remember severe performance problems certainly on LAN <-> WAN
traffic such that traffic was being limited to about 1Mbps.  Reverting
to 1.2 on the same hardware gave me the full 7Mbps of my ADSL connection.
