Have patron that needs to connect to VPN outside of campus, want to check if this will go thru our firewall.
To check if PPTP VPN port is open on your PC, use PortQueryUI, a tool used to check the availability of different ports.
1. Download PortQueryUI from Microsoft site: http://download.microsoft.com/download/3/f/4/3f4c6a54-65f0-4164-bdec-a3411ba24d3a/PortQryUI.exe
2. Run it, package will unzip to C:\PortQryUI folder.
3. Go to: C:\PortQryUI and run portqueryui.exe
4. Enter VPN server IP address or hostname, ex. us1.ibvpn.com
5. Select Manually inputquery ports and type 1723 port. Then press Query button.
6. If your result is TCP port 1723 (pptp service): LISTENING then your PPTP VPN port is open and you are able to conenct to our servers.
