I have a weird situation that I could use some help with.
I have a customer that is using an RFC 1918 range internally. One the remote end of an IPSEC VPN a vendor is using in part some of the same block. I need to be able to NAT two system to new address for bi-directional communication. I also need to be able to let those two original system to be able to access the internet as needed being globally translated to the address already in that pool/interface on the original customer PIX.
