Why is my PPTP connection failing with “VPN Gateway Not Responding (GRE)”?
The PPTP protocol consists of two components: one using TCP transport (also used for websites) and another using GRE transport. The latter often causes issues.
If your internet provider or router does not fully support GRE, VPN Tracker can initiate the TCP part but fails to receive a response when the GRE connection starts.
To check if your network supports PPTP connections, use the VPN Tracker Connection Checker. If the result does not indicate a successful connection, verify your internet setup.
Some routers require “PPTP Passthrough” to be enabled for GRE to function correctly. Check your router’s manual for instructions.
