I'm having major difficulties with getting some SSL sites to work through ISA 2004. For example, if I attempt to log on using the CEO portal at Wells Fargo (http://www.wellsfargo.com/com/ceo/ceoservices.jhtml), I get a 502 error. The firewall logs just show an SSL-Tunnel protocol attempt being rejected by the Default Policy. Other SSL sites work fine, so I'm theorizing that they are attempting to use an alternate port for SSL. Anyone else having troubles like this?
