I have a PPTP server that I can connect to using its LAN IP, but not using the external IP. My router is set up to forward PPTP to the correct machine and the server can access the internet. However, I cannot use my public IP to connect to the server.
Is there a setting in pptpd that blocks external connections, or is this more likely to be a problem with my router?
I have successfully used a PPTP server on the same network before.
(It was running on the same machine, but the OS has since been reinstalled. Could that have an effect on the current setup? What about assigning it a new local IP?)
Running ubuntu server 14.04
