I swear this worked 2 weeks ago from my old place in the states, of course now in london it doesn't work. Setup is a MacBook running 10.6.8 server in my dad's basement. It has a static IP 192.168.1.40. That IP is in the DMZ of an actiontec router connected to 20/20 FIOS service. I have PPTP enabled (40bit and 128 bit) and using MS-CHAPv2 for authentication. Here are the logs from the server. Possible issues. I am trying to connect via tethering to my mobile phone. I am pretty sure i did this 2 weeks ago and it worked fine. But that was on t-mobile and now i am on Three.
