I have three sites which are connected together using a firewall based IPSEC site to site VPN. I also have several machines which connect to a server using SSTP VPN for remote access. The issue is that the machines which are connecting using the SSTP VPN are only able to connect to machines on the local subnet of the server which they are connecting and not the other sites. I found a work around in adding a static route manually on machines; however these machines are out of my control and the users aren't exactly "tech savvy". If I try adding a route using the routing and remote access console I loose access to the network which the route relates to.
How can I overcome this?
Any help is greatly appreciated
