Site-to-Site TO Site-to-Site VPN Communication

Have the following configuration where site-to-site VPNs work fine. Cannot communicate from one end to the other directly.

Site A <---- VPN ----> Site B <----> VPN <----> Site C

Communications between Site A to Site B and Site B and Site C work fine. Site B is central facility. However, I cannot communicate directly from Site A to Site C and would prefer not to setup a Site A to Site C VPN. Are there special policies that must be set to accomplish this? All VPN tunnels terminate on the outside interface of the participating devices.

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Perhaps you need to add a route from site A to site C and back on the interface at site B, and also at sites A and C.
Do you get an error? if yes, what is the error?
