12202 Forefront TMG denied the specified Uniform Resource Locator (URL) when accessing website with port (p.e. Link:80)

Hi,

I have a rule that accepts all inbound and outbound traffic, but sometimes, some links (external web pages) don't open with the error above.

I can't understand why is this happening, and also, this can happen for some time and suddendly starts to work normally (until the next time).

What is missing in the config of the TMG?

  • Error Code: 403 Forbidden. Forefront TMG denied the specified Uniform Resource Locator (URL). (12202)

I don't have for sure, but I don't know if this is regarding the port on the end of the link (www.link.com:80).

I can't understand why this is happening.

Can anybody help?

Thanks!
