I am working on a test TMG server. I have included allowed domains by wildcard (*.*. and *.) as well as specific domain as it was configured in our ISA 06 setup (which works flawlessly). All the rules are the same from ISA to TMG, however the strangest thing happens.
When I make a change and apply, a particular website is now blocked (that is in my allowed domains list). The error code 502 (12202) comes up. Blocking the URL. When I read into this I see that this is caused by content being blocked. Looking through I don't see any reason why content would be blocked. For example, if I add youtube and cnet, I can view and download anything I want. So executables are not being blocked, nor are embedded elements.
The site in question is yorkcountypa.gov.
Some background. This is a VM with a single interface acting as a proxy ONLY.
I can provide specific screen shots and configs if needed, but don't want to spam them yet. So just let me know what you want to look at.
