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).<br />
<br />
If that works, you can be certain that RRAS works, and that leaves the WatchGuard as culprit. Testing from LAN with the public IP <u>might</u> 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. &nbsp;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. &nbsp;2 of those I know are unfiltered.

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
