Router Security - Turn Off Stuff
PPTP traffic uses TCP port 1723 and IP protocol GRE (Generic Routing Encapsulation, IP protocol ID 47), as assigned by the Internet Assigned Numbers Authority (IANA). PPTP can be used with most firewalls and routers by enabling traffic destined for TCP port 1723 and protocol 47 traffic to be routed through the firewall or router.

If you have followed the above steps and still cannot connect to the VPN, try forwarding the PPTP Port (1723) with TCP protocol to the LAN IP Address of your router (i.e. 192.168.1.1). Although it seems like this is a weird approach since you are using your router to forward to itself, it often times allows the VPN connection to suceed.

What Is PPTP: Point-to-Point Tunneling Protocol Jul 09, 2020 linux - change default PPTP TCP port - Server Fault Is there a way to make pptpd listen for PPTP trafic on a TCP port other than the default 1723 port? I khow that PPTP uses more then just tcp/1723. It also uses GRE. it's not a problem. just how to change default PPTP TCP port. And how to configure pptp client on linux to use port other than the default 1723 port
