How do I find ports used by an host in DMZ?
Posted: Thu Sep 24, 2020 12:47 pm
Hello,
I have a Raspberry in my LAN, acting as VPN server, behind Gargoyle.
As per documentation, the VPN should be using port 1723 only.
Anyway, when I set-up port forwarding for 1723, both protocols, the VPN client does not connect.
If I set-up DMZ to Raspberry IP, the VPN client connects.
Now... obviously I don't want the DMZ to be set-up there, so I'd like to check what ports are in use when VPN client is connected.
How can I "sniff" the ports?
