Hi all,<br />
<br />
Hope you can help, I have a strange issue here.<br />
<br />
I have an external site on port 8080 that some users on my internal network need access to.<br />
All other sites through our TMG proxy work fine. <br />
<br />
The site URL looks like this <a href="http://x.x.x.x:8080" rel="ugc">http://x.x.x.x:8080</a><br />
When I access this on a connection not protected by a firewall I can access the site without issue.<br />
<br />
<br />
Through TMG I get this error:<br />
•Error Code: 502 Proxy Error. Forefront TMG denied the specified Uniform Resource Locator (URL). (12202) <br />
<br />
I then thought of testing another site running on port 8080 to test and TMG forwarded the request without issue and opened the site.<br />
<br />
Why can I not view the site with address:<br />
<a href="http://x.x.x.x:8080" rel="ugc">http://x.x.x.x:8080</a><br />
<br />
your help is much appreciated.<br />
thanks,
