Windows Server 2008 R2 VPN connections were working now they are not

When I try to connect to my VPN connection I get error 806. Protocol 47 and port 1723 are being forwarded in the firewall. None of the firewall settings have changed and it worked last week. I have rebooted the server and firewall.
Firewall is a watchdog X20e
Clients are Windows 7

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Can you try to connect while on the LAN, using the private server IP? (Be prepared to optionally loose network connection if doing so, until disconnected from VPN).

If that works, you can be certain that RRAS works, and that leaves the WatchGuard as culprit. Testing from LAN with the public IP might work, but is no reliable test, as it depends on the device (WatchGuard) if it allows such hair-pinning traffic.

Works internal to the network using the server internal IP.  But to throw another wrench in the mix, if I use my phone as a hotspot it works. Yet 3 networks I have tried it has not worked.  2 of those I know are unfiltered.

What is the exact path when using your phone as hotspot? Client => phone (via WLAN) => Internet (via 3G or the like) => router => VPN Server?

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

Client -  phone - 4g - firewall - server

Sounds like being an external issue then. WatchGuard and VPN Server are working.
