Hi again,
Just wanted to know if that scenario can be handled by a m0n0 box:

a generic PC with 3 ethernet cards.

Card 1) WAN Link that on which wire there are (to say) a block of
IP's, imagine 192.168.1.0/24 (imagine those are WAN IPs!)
Card 2) Some servers, on which interfaces live the IP's of Card1.
Card 3) The LAN.

Then, is it possible to:

a) Bridge the 192.168.1.0/24 to Card2
b) Allow access from LAN to WAN with one of those IP's
c) make m0n0 not to have really one of those IP's, just a IP on LAN to
be managed

so in brief... make m0n0 be more or less like a bridge but doing nat
for LAN clients.

Thanks for all,
Marc
