I have the following issue with my VPN connectivity, the VPN connects, no issue there. I have made sure my home network IP range is not in the same subnet as the VPN network devices I'm attempting to reach.
Home Network: 172.16.x.x
VPN Network: 10.0.1.x
In order to connect to any of the devices in the VPN network, I have to disable the IPV6 to 4 tunnel ("Teredo Tunneling Pseudo-Interface") and generally have to renew my IP configuration after disabling that service and/or restart the PC altogether. The network works fine after I've taken those steps, but I have to do it every time I attempt to connect.
