Hi Guys:)/
I Want to Connect With VPN PPTP to Mikrotik that it is installed on VPS and have Static IP.
I Can Connect with my Mobile without any problem but my pc dosen’t Connect.
See Picture :

I think something wrong with GRE(47) and TCP(6) I Saw them in Connections Tab in Firewall . My Mobile Connect with TCP But My PC can’t Connect with GRE.
I Could Connect my PC with L2TP But I want Use PPTP because it is faster and that is important for me.
Please Help me. Tkanks
PPTP uses TCP 1723 and GRE. The TCP port is used for control and establishing the VPN and the GRE tunnel is for actually passing data. This behavior is key in understanding why it doesn’t traverse NAT without non-standard helpers on the NAT device.
Please clarify whether you are trying to setup PPTP client on the MikroTik router and that it has a public IP or a PC behind the MikroTik router. You state both in your post.
Also, PPTP is not considered secure. You may want to consider using a different protocol.
