Simple was the key word in my question, like kindergarten simple. I was curious if it would work in principle. It wouldnt help me anyway because it would be no faster than the present setup, A to B using the same T1. I already have the VPN set up so I can admin location A's ASA. (I can ping the ASA at location A (172.16.0.1) from location B's LAN. I cannot ping the ASA at location B (192.168.0.1) from location A's LAN)
I was thinking it would work something like this: The location B ASA already uses NAT for the TS behind it on the (T1). The present L2L VPN is also using that same outside interface. This scheme would require a different provider than the provider of the T1, using a different block of IPs. The tunnel would be established between location A's ASA and the new ISP's router at location B. That traffic would be handed off to the ASA which would NAT it through to the TS. Yes, no, lame?
Pushing the boundaries of disorganization.
