unless you have added your ip address to your cert & to the isa pub rule this is as expected.

Now I an getting * Error Code: 403 Forbidden. The server denied the specified Uniform Resource Locator (URL). Contact the server administrator. (12202) There are suggestions that you will get this error message if you do not use the exact url which was specified in the rule. I am trying to bypass the FQDN until this has been chnaged by our isp. I need to test that the rule will work ok ________________________________ From: Patrick <london31uk@xxxxxxxxx> To: exchangelist@xxxxxxxxxxxxx; exchangelist@xxxxxxxxxxxxx; msexchange@xxxxxxxxxxxxx Sent: Monday, January 12, 2009 1:34:58 PM Subject: [ExchangeList] owa 2007 connection error Hi Guys, I have managed to install the new cert on our exchange 2007 server and isa 2006. However when we try to login we get the following error. * Error Code: 502 Proxy Error. Connection refused(10061) * IP Address: xxx.xx.xxx.x * Date: 12/01/2009 13:29:31 [GMT] * Server: Main-isa01 * Source: proxy Not quite sure what we are doing wrong. The thing is we are using the external ip address of the isa server to redirect to our exchange site until our isp makes the necessary dns change. so it is https://123.23.19.45/owa and then we get the above error. Thanks Patrick
