Nov 21, 2017 · Re: ASA SIte to Site VPN with NAT Here you have to think about the order of the NAT processing. If you want to NAT a specific host through the VPN, this statement has to be placed before the NAT-exemption in section 1. The specific NAT to the internet has to be placed before the general PAT to your interface or PAT pool. To create a tunnel without this conflict, both networks must apply 1-to-1 NAT to the VPN. 1-to-1 NAT makes the IP addresses on your computers appear to be different from their true IP addresses when traffic goes through the VPN. 1-to-1 NAT creates a map from one or more IP addresses in one range to a second IP address range of the same size.

A VPN tunnel cannot be established if both the destination network and the local network have the same subnets. The Apply NAT Policies feature or NAT over VPN is configured when both sides of a proposed site to site VPN configuration have identical, and hence overlapping, subnets.

Apr 13, 2020 · Network Address Translation. It is not uncommon to use Network Address Translation (NAT) when configuring Always On VPN.
