I'm curious to know what the LAN side and WRT54GL side of the m0n0 are
configured for filtering, etc.

Also, can you move them to seperate cards in the m0n0 box?  Maybe
you're running into interrupt conflicts/delays, which are slowing
things down?

As a test, I'd disable any and all filtering, maybe set the m0n0 into
bridge mode between the two subnets and see how that works.  

Are you seeing any errors on the interface statistics screens as well
on the m0n0wall?  Maybe you have a duplex mismatch somewhere?  Check
the stats on the Myth backend and the WRT as well, see if they're
seeing interface errors or not.

As always, simplify, change one thing at a time, and test test test.
:]  Oh yeah, write down what you change each time, god knows I've not
followed my own advice and ended up down a rat's hole of confusion
until I backed out to a known working configuration.

Good luck!
