We have setup a triangle of LAN to LAN VPN's using IPsec. In the offices it all works fine, databases can be retrieved etc. However it appears not functional when you remote in from out of these sites into the matrix.
I have a user or two that like to work from home sometimes and need to access documents and databases from all 3 of these sites. When they client server VPN into one of the sites, they don't have network and file access to the others. One of the sites is set on a 192.168.1.xxx which is usually what most home networks are set on. However the other site should have no problem.
The site they VPN into we'll call site 1. Site 2 for the site that should have no problem and site 3 for the 192.168.1.xxx.
Home user connects to site 1 from home and can access site 1 resources. However cannot access site 2 or 3 (like I said I think I know the reasoning behind site 3). In the office it is all fine. The remote dial in user is set on the router. I assume that the user is smart enough to enter his windows credentials without getting scared of a username and password box, however this might just be the case.
Any other ideas would be appreciated.
