I'm trying to set up multiple site to site vpns with an ASA 5510 at the main site and 5505's at the remotes. I'd like to use the 5505's behind the existing internet routers at the remote sites, typically linksys or similar dsl routers.
At the main site there is a host with the private address of 10.1.X.Y which I need to have bidirectional connectivity with PC's at each remote site. The remote sites all have private IP's of 172.16.A.X, 172.16.B.X etc...
The 5510 has a public IP on the outside and the inside interface is in the same subnet as the 10.1.X.Y host that I need access to/from.
Assuming that I have a 5505 with 10 user license, is it possible to locate the 5505 BEHIND a linksys dsl router to allow 10 users on that private net to access the remote host over a tunnel?
What I was hoping I could do is configure 172.16.X.1 (the dsl router) as the default gateway, and have a static route on that router that points any traffic bound for 10.1.X.Y to 172.16.X.254 (the inside address of the asa 5505) which would then get to the host over the point to point VPN.
Is this possible? Any and all help GREATLY appreciated.
