Our users need to connect to a web site publishing https in port 1213: https://marketplace.superbuy.com.br:1213/index.jsp The ISA web proxy log shows error 12204. The only reference I found in Technet is Q184028 - 12204 SSL Port Specified Is Not Allowed. This Q article is about Proxy Server but I assume ISA Server behaves the same way, and connection requests for Web sites containing a port number in the URL for ports other then 443 will fail. This article also describes a registry key for Proxy Server with the allowed SSL Ports. Is there a way to allow 1213 port for SSL in ISA Server? Any other idea? Other than telling my users to forget about this web site? Thanks Alberto Boczar att/PS Informática S.A. Brazil http://www.attps.com.br * aboczar@xxxxxxxxxxxx
