L4 NAT from internet to internal

[ohassairi]

is it possible to do the following: people from internet will connect to many internal servers (with different services:web, DNS,ftp,smtp...each server has a unique service) using just one public IP address.

PIX wll then forward IP packet to internal server based on destination TCP port.

the goall is to save public IP addresses

Could do port forwarding, yes, no problem, which is a sort of NAT.

However, given the capabilities of your device, you should see about some sort of VPN to configure, or just forward to an internal VPN server.

[ohassairi]

is it supported by PIX firewall (ver 6.3(3))?

or it is a router feature?

is a there an example in cisco web site?
