    Does Sveasoft support port forwarding of multiple WAN IP addresses to internal machines?

    Do you mean assign multiple WAN IP address to the router then forward to internal addresses? The answer would be yes, but not an easy thing to get working nor would it be likely to get it running well using Alchemy. I would suggest you have a look at dd-wrt to see if it could do it for you. Main idea would be to remove one of the ports out of the primary VLAN and move it to its own VLAN and use iptables to handle the routing. I have yet to see anyone post sucess doing this.

    BTW, for the record I don't have enough knowledge to get it working so I won't be much help to ya if you still want to try it.

    What you are trying to do is most easily accomplished by installing IPCOP on an old tower. IPCOP is a linux build that has just enough code to build the firewall. It supports multiple WAN addresses using nic aliases. You can do port forwarding from the external nics to servers on your lan or you can do 1-to-1 Nat, the choice is yours.
    If you dont like IPCOP you can also build a linux tower and run shorewall or smoothwall or FWBuilder and get similar results.

    Again, you can install any of these of a Pentium III tower with 128 RAM and a small hard drive. Once it's setup just enable SSH to maintain it and unplug the monitor/mouse/keyboard and place the tower by your ISP modem and you are good to go.

    note: you will need at least 2 nics in the tower for routing. try to get nics that are linux friendly to minimize installation stress.
