Well, I did some installing and installed ufw and added 1723 and 22 to the allowed list.
Also strange: when I use the command
I get no response.
service pptpd status
I enabled logging on the firewall and I can see that I'm getting blocked.
I can't add the port 1723 to the allowed list, as it's already on there. I obviously restarted the service too.
