I have a VPN lab setup between 2 routers into a vlan to act like a VPN:
Router 1 FE > Switch with Internet VLAN < Router 2 FE
The routers only have 1 FE port each, so these act as their external interface, each router has a loopback interface to act as their local LAN.
Now I want to assume that both LAN's (loopbacks) use the same IP range, I would like one of the routers to NAT so each LAN can communicate so one of the LAN's uses a completely different IP range. How can I do this? I assume I will need another device to provide the NATing?
As mention "I have a VPN lab setup between 2 routers" sorry if this wasn't clear.
Anyway I have a VPN lab setup and now want to assume that one of the sites IP ranges (on the loopback) is now the same range as the other site (also on the loopback), I want to NAT one site so they can ping each other.
I've created VPN's before between companies but have yet to have it where my LAN's IP clashes with a remote site/company but it will happen, so I need to practice this.
My 2 routers only have 1 FE each which go into the "internet" vlan on the switch, I have created a loopback on each for the LAN of each site.

interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
