[c-nsp] PIX IP Aliasing

[rwcrowe at comcast.net]

Unless I'm unclear on your requirements, you don't really need a secondary interface, just a free public IP address from your external pool.

To translate tcp port 80:

static (inside,outside) tcp x.x.x.x 80 y.y.y.y 80

To translate udp port 53:

static (inside,outside) udp x.x.x.x 53 y.y.y.y 53

You can translate either tcp or udp and any port.
Where x.x.x.x is a free public IP address and y.y.y.y is the IP address of the internal host.
