Heya --

	Congrats on the separate firewall.  If I were you, I'd also set up your servers behind it to log to it, just so you have logs in separate places in case of evil.

	What are these?  Haven't seen those before... do you remember what syntax of commands you used to enter these routes?  I assume some variant of route add...

	Ah, I'm pretty sure you have to give it -netmask 255.0.0.0 at the least.  You may have to give it the whole rest of the line.  Since the Linux routing kernel uses classless addressing, you pretty much always have to specify the netmask.

	Also, why are you specifically telling it how to get to 64.0.0.0?  It should just follow the default path for that.

Cheers,
