I have the following scenario:
Pix version 6.3(3)
DMZ interface with a private network (192.168.250.0/24) with some server configured static NATs to be accessible from the outside.
Outside interface with public IPs
I have to establish a lan-to-lan tunnel with a customer so he can access our DMZ. Our problem, is that the customer has our same private network. I'm trying to solve this problem with policy NAT. However, I can reach the customer DMZ while the customer is unable to reach our DMZ. In the past I solved this problem with route-maps on Cisco routers. Is it possible to solve this scenario with a PIX without modifying our network? How?
Thanks in advance.
