I haven't had the opportunity to play with m0n0's VLAN support yet, so 
please be patient if I'm asking any dumb questions.

My understanding is that from a firewall/NAT/ruleset point of view 
m0n0wall treats VLANs as seperate ethernet devices? -- Is that correct?

Do I still need seperate WAN and LAN  NICs, or can they be VLANs on the 
same NIC? -- The goal is simply to free up a few ports on my switch 
(Which has both 802.1q and port-based VLAN support).

Since I'm running 100Mb NICs, and only have 5Mb/1Mb of bandwidth 
available it's impossible for me to even come close to choking a single 
NIC, so I don't see a significant speed problem here.
