 Posted: Tue Jun 16, 2015 1:00 pm Post subject: PPTP VPN suddenly not working... |
 |
|
I updated last week and suddenly I am having major issues with a few PPTP VPN servers. My Galaxy S4 can connect to the VPN in question every single time, no issues. However, my Gentoo system is now doing this, every single time.

I am not sure what is wrong here. The server uses MPPE encryption (128bit) and I have the correct options in the VPN configuration. It worked prior to the update.

I figured this out. It is related to my firewall. I am not sure what though. I will continue this on my firewall thread here.

Solved! You can find the entire post here, but the solution was to allow the GRE protocol into the system. Apparently it does not work with the related/established rule.
