    I have a site-to-site VPN tunnel up with overlapping networks between two PIX firewalls.

    Each side considers 192.168.x.x to be their own and nothing addressed for 192.168.0.0/16 is routed to the PIX for the internet.

    I accomplished this using static NAT. If you'd like to see the configurations for each PIX (works on 501 and 515 and I presume, the 505), see each line explained, and also have a decent template for the required documentation, check out this Word document:

    Tested and in production.

    This document was the template for a tunnel which is now up and being used for production communication. Consider the configuration verified.
