I have always heard that there is no way to leave a port open with Microsoft Proxy Server 2.0 and have it hidden. Does anyone know a way around that limitation of proxy (without the use of additional hardware/software)? Thanks in advance for your help.

Hi,

Errr.... I'm not quite sure what you mean by hidden? My understanding is that if its permanently open, then it can be used to connect through and any "port sniffer" will be able to detect that...

Cheers,
Tim.

Some firewalls will leave the ports open, but hide the port from a port scanner. I wasn't sure if there was a way to do this with proxy.
