The situation is as follows
Building 1 (B1) is my main site. I have 1 Windows Server 2012 unit at B1 and B2. B1 is a PPTP server.
At B2, I have many devices. Most of these devices are constantly on a VPN connection to B1 (including the B2 server).
Can I set some devices at B2, such as IP phones that do not have VPN abilities, use the B2 server as a sort of "Default Gateway", and then have the B2 server route these devices over its VPN connection to B1?
I am aware that there are better alternatives, however most of those require more advanced hardware that I could not afford. I already know for sure that the B2 router does not support VPN connections (but it lets them through).
