I have a site with no DC and users authenticate across a point-to-point VPN tunnel. I believe the port is being filtered by a piece of hardware and I need to know what port it is that I should be seeing in my packet capture. Any info would be helpful.

The key to successful tunneling using PPTP is the ability of the ISPs involved to support Protocol 47 and Port 1723

I found out that a piece of Hardware - Link Load Balancer from Barracuda was filtering the ports. After a quick reboot I was then able to get through. Thank you for your help.
