Hi,

by default ISA only allow the 443 port for SSL connections, if you need to use an specified port to SSL connections, check this article: http://www.isaserver.org/articles/2004tunnelportrange.html

Paulo Oliveira.

Hi,

you can´t edit the default protocols that comes with ISA. In your case, you need to create a new protocol allowing the 8443 port and add to your rule.

Note: The http and https protocols, allow respectivitly the 80 and 443 port.

Regards,
Paulo Oliveira.

try to disable authentication on your ISA server. The logs are telling ISA is requiring authentication and not blocking the 8443 port.

I have a question regarding allowing TCP Port 8443 outbound via running the ISA Tools script.

Once you execute the script I understand that you are now allowing port 8443 to be allowed outbound.

Is 8443 then considered part of the HTTP protocol or part of the HTTPS protocol?

Is it possible to limit access to a website that utilizes port 8443?

Or, is that now impossible once you run the script to allow 8443 outbound?
