VPN with overlapping IP addresses
Posts: n/a

Since we are not very familiar with Cisco's VPN functionality, we have
the following problem on a PIX 506 (PIX Version 6.2(2))

Company A + B both want to establish a VPN to Company C.

A has the same subnet as B: /24, C has a different one.

A established VPN to C with - works fine, nothing to do.
C told B to use for VPN and to do NAT to avoid conflicts.

I don't know how to realize this on the PIX at B's side (changing the
whole internal subnet of B is not possible!)

Would something like this help:

static (outside, inside) netmask

May this be right for the access-list?

access-list 100 permit ip company_c_net
nat 0 access-list 100

Thanks for your help!
