--> vmbr1 (10.0.2.1) --> VM pptp server (10.0.2.2), and other win10
--> vmbr2 (10.0.3.1) --> VM pptp server (10.0.3.1), and other win10

Specify exactly source and destination (IP, port, where they are located) about working respectively not working connections.

If you post a pvereport some of the questions above would be answered implicitly.
 
Hi, yes it still open.

The pptp connect from internet to subnet on vmbrX.

I don't understand your question, the eth0 is the interface with external IP connect to internet but its no under any vmbrX.

The expect network its:

from any IP from internet we expect connect to the ip:port - 91.121.210.82:1723, and then the nat translator connect to 10.0.1.2:1723. When connection is established the pptp server give a IP on the networks 10.0.x.x/24.

How can i do a pvereport?

Kind Regards.
