Software firewall and static nat

[csteinsv]

I am looking for a software router/firewall Linux or WIn 2000 that is able to do static and dynamic nat.

I have 4 ip's would like to nat. two static nat for two serveres and one dynamic for providing internett access to the rest of the network. The last one static to a DMZ server
Also if the software is bale to do firewall services that would be exelent.

Does anyone know of a software that does this? Besides Checkpoint FW-1 (kinda out of my price range)

Well, one option is IPTABLES on a linux or unix box. That can almost do what you want.

http://www.netfilter.org/

You would need to put 2 NICs into a linux box, and configure the one NIC for your 4 static external IPs, and one for your internal network.

You would then create the nat rules based on the input destination IP address. All of the hosts would reside on a single internal network with seperate IPs.
