Softether VPN Setup Help!?!?

[ServerMonkey]

Hi there! I'm currently trying to setup a VPN using a VDS and softether on Windows Server 2012 R2. I'm using a laptop to connect to the server via Wifi, then bridging the VPN connection with my ethernet connection linking to my XBOX360 for a xbox live connection.
This setup does work, but I keep having having connection issues. Disconnecting from parties and lobbies etc... Anyway, when running a network test on the XBOX it keeps bringing up a NAT Type is Strict Error. I have all my firewalls turned off, both on the VDS and the laptop.

I've been trying to fix this for DAYS now and its driving me insane. So, if anyone could shed a little bit of light on this and give me some help, i'd really appreciate it!!

Thank You!!
