Hello everybody,

I need to connect two networks together.
Those networks have total different IP ranges.
Each machine in network A needs to connect with a unique "nat'ed" ip 
address to the network B, but it needs to keep its own MAC address (or, 
if this is not possible, a fake one).
I try to use FREEBSD 5.2.1 with  NAT to do the job but this sends as 
espected the mac address from the router to de destination host, in my 
case this is not allowed.

PS A little bit firewall is welcome to.

Can this be done?
Perhaps with netgraph?
