There are hard-coded rules (anti-spoof check for LAN and OPT interfaces)
in m0n0wall that cannot be disabled. Because of the "quick" keyword,
user-defined rules (which come after the anti-spoof check) have no
effect... Not a bug, a design choice. Sorry :-(

Read the code in filer.inc and you'll see why.
