PPTP (VPN) Connection not loading all web sites?

In question is too high MTU value, this is quite easy to solve with simple single command in command line.

Unfortunately this cannot be set server side, and we will be looking at how to fix this directly server side, but for now a quick workaround is to correct the MTU value to 1250.

Click start button and type in the field "cmd", you will see a black console icon, right click on it and choose "Run as administrator".

You will then see the console and there type in this command:

netsh interface ipv4 set subinterface "VPN Connection" mtu=1250 store=persistent

Replace VPN Connection with what name you used for the VPN connection, you can also view the connection with:

netsh interface ipv4 show subinterfaces
