To add a PPTP server on the RouterBoard? In Winbox you add it in the PPP menu.

Thanks for reply but i mean the services ports

Activate the PPTP server and the service port 1723 is automatically opened. No need to add anything in services.

The ports are preset in the PPTP server. Were you looking for a way to move the PPTP server from the standard ports?

Yes i will use other port.

I don’t think that the RouterOS PPTP implementation lets you change the ports on the PPTP service itself. Sometimes the ports are complied into the PPTP module. You could consider a NAT arrangement but I would check that the clients support different ports first - not all do.

Thanks for reply and effort
