Hi.
I'm trying to merge two "servers", one of them is only a NAT-router for 
the rest of the LAN another one is a host without NAT that needs a 
unique IP. I have 3 network interfaces on the other. I want that to take 
over the NAT-routing, but I need to use one network device to that 
server, and one other to the NAT-routing. All connections from this host 
should go thru ed0 without NAT.


    Server:
     NIC0 (vr0): NAT-network - rest of the network (NET0) - Switch 0
     NIC1 (ed0): Default outgoing interface - Internet (NET1) - Switch 1
     NIC2 (xl0): LAN (NAT'ed thru vr0) - Internet (NET1) - Switch 1

xl0 and vr0 is on the same switch to the same network, but with 
different IP's.  Is this possible?

And another network question: Is it possible to make a virtual network 
interface bridged to another one?
