My ISP says I could have up to 4 IP's for one connection. It also says
that this is usually used, when connecting the modem to a switch using
crossover cable. The clients then get a public IP address via DHCP.
Is it possible to set up the WAN interface to get 2 or more IP's? For
First IP used as a 1:1 NAT to my Server (as it would be connected to the
switch directly) and
the second IP for my LAN (6 or 7 clients).
