Hi,
I’m connecting to the internet through a “RouterOS v6.37.1” Mikrotik
whenever I try to login to my PPTP VPN service, I simply can’t.. I just get this message in progress :

and then, this message:

I’ve contacted the network administrator, he doesn’t know what to do.
I’m looking for a method to allow such connections in order to forward it to him..
what should we do ?
Without seeing the configuration of the VPN Terminator, no one can tell you.
The PPTP server should have two firewall filter rules.
Chain=Input, in-interface=wan1, proto=tcp, port=1723, action=accept
Chain=Input, in-interface=wan1, proto=gre, action=accept
Since PPTP works with the GRE protocol, it’s easy for hotspots like airports to block PPTP connections. Some home based cheap routers (or ISP provided routers) may not support the GRE protocol. Although I think most will.
