Hi guys, This should be an easy one for you all, but it is eluding me. Internal client tries to access a non standard Secure web site (port 9443). It crashes with this error, Network Access Message: The page cannot be displayed Technical Information (for Support personnel) a.. Error Code: 502 Proxy Error. The specified Secure Sockets Layer (SSL) port is not allowed. ISA Server is not configured to allow SSL requests from this port. Most Web browsers use port 443 for SSL requests. (12204) b.. IP Address: 10.0.0.1 c.. Date: 12/13/2006 1:18:16 AM <LI If we disable all proxy info in IE connections, and just use the NAT it will go thru. I have tried a bunch of stuff and not getting anywhere. I have been out of this field for sometime now and am certainly rusty and doing something wrong. Please tell me what I am doing wrong and what I need to do to all it to go thru using proxy server. ISA server 2004 on a Windows 2003 standard Machine. XP clients. Thanks Mark
