I'm racking my brain, I've done this before but I'm doing this in another lab environment . Non-Domain computers (Outside) trying to RDP in via the Gateway (Domain-Internal is working). Certs aren't an issue as they're installed, I've tried it multiple ways, but for now I'm using the self signed generated via the RD Gateway manager. I can go to https://rdgatewayurl/rpc and authenticate and get a blank page (external and internal).
New Domain, 2k8R2 Functional Level, no real GP customization at all, except not requiring NLA and enabling RDP on the internal "servers" in a specific OU. My Account has Admin privileges on all the servers in question.
Another stupid question: This should also work with just the RD Gateway role installed, right? I've tried it both ways with no luck.
RD Gateway is logging Event 4625 in the Security Log. I feel like this should be obvious but my brain is fried.

It is generated on the computer where access was attempted. The Subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe. The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network). The Process Information fields indicate which account and process on the system requested the logon. The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases. The authentication information fields provide detailed information about this specific logon request. - Transited services indicate which intermediate services have participated in this logon request. - Package name indicates which sub-protocol was used among the NTLM protocols. - Key length indicates the length of the generated session key. This will be 0 if no session key was requested.
