We have a slight problem that hopefully someone has an easy answer to.
We have an SBS server (2003) that we are using for various things including using the ISA functionality.
The problem we have is with an application that needs to communicate with an external server using SSL.
The application is configured to connect to a certain IP on port 443 every day - but we are having difficulty getting this to work.
The only way we can get it to work is to configure the software to connect using the Proxy with a name and password AND we have to configure ISA to allow basic authentication - it appears the application does not support any of the other forms.
This is not an acceptable solution as our client does not want Basic Authentication enabled.
We have tried to get the software to work without using the proxy - i.e. to go straight to port 443 on the remote machine but the firewall is blocking us and we can't seem to get around it. We have tried creating an IP packet filter for the port - does not seem to work (refer
http://www.microsoft.com/resources/documentation/isa/2000/enterprise/proddocs/en-us/isadocs/cmt_othersvc.mspx).
We can access HTTPS sites through a browser we just cannot access them directly i.e. on a workstation connected directly to the internet (no ISA) we can telnet to the remote IP on port 443 i.e.
telnet x.x.x.x 443
We get a connection. When we try this on the SBS server the connection times out.
Can anyone provide insight as to what configuration changes we can make to allow the application (which runs local on the SBS server) to connect to the remote server on port 443 without enabling Basic Authentication for a proxy connect?
