Hi,
I developed a MFC-Based TCP applicatoin,which client part runs in LAN PC and
need to across MS ISA Server via HTTP proxy to connect to the server part in
Internet . Our HTTP proxy port is 8080. I have created Protocol Rule and
Site & Content Rule to enable the TCP port for my application. But I got a
502 error in received buffer after I sent 'CONNECT' command.

The total message in buffer is as belowed:
'HTTP/1.1 502 Proxy Error (The specified Secure Sockets Layer(SSL) port is
not allowed. ISA Server' is not configured to allow SSL request from this
port. Most Web browsers use port 443 for SSL requests.) Via:1.1 XXXPROXYSVR
Connection:'.

I looked up this error message in document of ISA Server. But I am not sure
if the error resulted from ISA Server configuration or my application. What
should I do to get rid of this error? Any advice or samples?

By the way,we know MS ISA Server support SOCKS V4,which enables LAN applications to
across firewall. I want to know if it supports SOCKS V5,too.

Thank you.

Try to enable SSL Tunneling in ISA server properties. Must work.

And then, should I use that SSL port as HTTP Proxy port for my application to connect to Proxy Server?
Thank you.
