Hello - I am trying to bring up a second site to site vpn tunnel to a site where I have an existing one, and I am having issues. Here is the lay out: Right now I have site A and site B, both sites have an ASA 5520. In site A I have a link out to the internet on gi0/3 and a link to the internet via a different ISP on gi0/2. In site B I have the same setup, gi0/3 to one ISP and gi0/2 to another. Currently I have a site to site VPN tunnel that is working from A -> B via the connections on ports gi0/3. Now, I try to add a second site to site tunnel via the wizard in ASDM for site A -> B on the ports gi0/2, and as soon as I apply it, I lose the first tunnel, and the new one does not come up. As soon as I remove the second one, the original tunnel is restored. A little confusing I know, but any help would be great.
I have this problem too.
