Question : PIX routing inside to inside

Hi!

I'd like to configer my cisco pix 515e version 6.3(4) to do routing between two interna IPs.

If someone on the inside connects to 12.34.56.78 I'd like the request to go to 21.43.65.87. Something like

static (inside, inside) 12.34.56.78 21.43.65.87 255.255.255.255 0 0 (wich doen't work :) )

Thanks

Answer : PIX routing inside to inside

Cannot do with PIX.
Problem is one of design. By design, a packet will not be redirected back out the same interface it came in on. Also, nat process of operation requires that packets actually pass through two interfaces . .

A PIX is not designed to be a router, it is designed to be a firewall. Not even with Cisco IOS router can you do what you're looking at unless you want to try using a router and  "nat on a stick" concept which Cisco does not support and I have never been able to make it work:
