Addres translation on inbound traffic

[hcombee]

We have an external company that wants to connect to a FTP server on our network. Between our networks is a PIX firewall. On this external network are clients using the same addresses as one of our subnets.

Does anyone known if it is it possible to do PAT on the source adresses of this external network? (So it''s not PAT from inside to outside but from outside to inside)

What you need to do is to use the alias command see here for an example

or with 6.2 software use outside nat
