I have a scenario whereby I'm using a router based VPN to terminate my site-to-site tunnels and my T1 connection.
I have a 3rd party partnernet that I need to connect to, and they have provided me with their own hardware to connect. I would like to continue to use my current T1 circuit, but I have a problem conceptualizing how this would work.
Essentially, I need to have a VPN router pass-through other VPN traffic that it was not intended to receive. I don't want to have an access-list or lack thereof block my traffic that was intended to be 'passed through' to my other VPN device.
