Has anyone been able to pull any magic off that allows PPTP connectivity over sprint's 3G/4G wireless network?
I assume they're just filtering it flat out, but before I contact them I wanted to see if anyone has found a resolution on their own.
I have several Nexus S 4G devices which are unable to get PPTP connections over 3G/4G but if you enable WIFI it comes up instantly.
I've been researching this off and on all weekend but wondered if anyone else had run into this issue.
I use often use PPTP on my original HTC EVO. Just tested it now and it worked. 3G only, no 4G in my city.
I have seen MTU issues with PPTP on cellular networks before with Android. You might want to try clamping the MTU down on the server side.
I had issues with older versions of Android, but those manifested themselves as the PPTP tunnel would connect but no traffic would pass over it. It was either the last update or the one before last that resolved it for me. ~Seth
