PPTP Firewall

Hello!
I have a RB750 that just configured to work directly with internet via FTTH. I connect it directly to my ONT (from Orange, indirect NEBA) using VLAN 20. The internet is working. My RB gets my static IP. But when I try to access my PPTP VPN from the internet I can’t do it. I created 2 rules (1 for tcp 1723, 1 for GRE 47 protocol id) in firewall, but nothing happens. In the log I can not see the connection being made.

Any help? I’m just starting with this.

Hello, you need to enable PPT Server. Go to PPP then PPTP Server or via the terminal past this line : /interface pptp-server server set enabled=yes

Hello! I did it.
Anyway, i found the problem. I was dropping the connections in other rule in the firewall. Thanks!
