Hello -

Here's the scoop (simplified) -

Three sites, A, B and C.  There is an ISA 2004 Standard Edition server at each location and they are currently configured with site-to-site VPN in a hub and spoke configuration (site A is the hub).  A can talk to B, and A can talk to C - no issues and all is well.

However, I want B to talk to C.  This currently does not work as site B has no idea how to get to C - even if it did, the ISA Server at A needs to know to allow and route the traffic.

I do not want to do another site-to-site VPN between B and C.  (As I mentioned, this is 'simplified' - there are actually five locations and setting up a full mesh configuration with VPNs between each site is just too insane to think about.)

So how does one configure A (and the remote sites) to not olnly route but also allow this traffic and communication?

Hope this is clear enough to follow.  If you need more info, please let me know.

Thanks!
