Hi

Have configured PPTP in MT 2.9. It works fine from certain IP addresses. But disconnects immediatly from other IP address.

Thanks in advance.

You’ll need to give much more detail if you expect to get a meaningful response.

Many networks will not pass GRE protocol thru NAT. Or 1 at a time. PPTP needs tcp/1723 as well as protocol 47.
