Add different HTTPS port on ISA 2004

Posted on 2006-04-11

I am using MS ISA 2004.

We need to access an external website using https on port 444. I have changed the msFPCTunnelHighPort reg entry that is located under the following reg key to port 444:


However when I try to access the website I now get this error:

Error Code: 502 Proxy Error. The connection was reset by a peer. For more information about this event, see ISA Server Help. (10054)

I am not getting prompted to install the security certificate as I would if I was accessing the site from my home PC so I think the connection isn't even getting through the ISA server.

If I look at the HTTPS protocol propeties in ISA port 444 still doesn't show.

Any help provided will be greatly appreciated.
