Port Address Translation w/ PIX 515E

Unanswered Question
May 21st, 2007

Does anyone know if it is possible for a PIX 515E to do simple Port Address Translation (PAT)? Also, how many concurrent connections that would sustain?

Thanks,

Johnny

I have this problem too.

Yes its possible to do PAT on PIX. Here is an example-

nat (inside) 1 0 0

global (outside) 1 interface

Above commands will simply PAT all the inside network when going outbound to the IP address on the outside interface of PIX.

Here is a link which will help you understand hot NAT/PAT is configured and works on PIX-

Hope this helps.

Is this what you're talking about?

Translate a.a.a.a TCP/80 to b.b.b.b TCP/8080

If so, you would accomplish it as follows:

static (, ) tcp a.a.a.a 80 b.b.b.b 8080 netmask 255.255.255.255
