SBS2003/ISA Proxy 502 Error for SSL

Asked by: TimPeer

Getting the following error when I try to access any secure web site through the ISA/SBS proxy. How do I fix this? ICW was ran already and I did not see a property checkbox for SSL.

Thanks!

Tim

What ssl port are you trying to use - because it is not 443

 

by: TimPeerPosted on 2009-02-24 at 23:18:25ID: 23730991

I am not sure. How do I check?

In ISA? I ran CEICW and selected the defaults with FTP and Terminal Services.

Thanks Kieth

open the ISA gui - select monitoring - logging - start query
try the connection - watch the log
ISA only supports outbound ssl on 443 by default.
Get the ISA tunnel port range extender by jim harrison from www.isatools.org
download the isa_tpr.js file from the isa2004 section and save it to the c:\ of the SBS box

drop out to a cmd prompt on the sbs box
type in
isa_tpr.js /add portxxxx xxxx   where xxxx is the ssl port that you are trying to access (seen in the gui log)
