PIX multiple external IP addresses NAT to the same internal Web server

[mattwarren]

Hi,

We're trying to configure a Cisco PIX 515 to NAT multiple external IP addresses to the same internal Web server, but can't seem to get the NAT configuration correct - is this possible on a PIX?

E.g.

External TCP port Internal TCP port

212.123.1.45 80 192.168.1.10 80

212.123.1.47 80 192.168.1.10 80

I know this is an odd configuration, but we are replacing the current firewall with a PIX, so we need to replicate the configuration.

Thanks, Matt

The pix is not a load balancer - it cannot support natting multiple outside IP addresses to one inside, or vice versa. Just assign the inside web server multiple ip addresses, and use 1 to 1 static translations from the outside to the inside.
