Connect to a VPN server through a router?

Question

VPN

Hello.
There is a VPN server on the Internet on Windows 2008 R2.
At home there is a computer with the Internet from a certain provider.
When you create a VPN network on your home computer, a connection to the VPN server is successfully created through the "Network and Sharing Center", having a login, password and website address.
How to make a home router already configured for this VPN server and distribute the Internet while already connected to it?
ps router model D-LINK DIR-300 (yes, cheap, but there is no other)
pps there is no direct access to the VPN server, only the data that I described above.
