I understand that port 443 is for https traffic, but this is as much 
information as I have been able to get from EllieMae's tech people.  It's 
almost sounding as if setting up 3-4 machines to bypass ISA would be the best 
option.  Is removing the client from those 3-4 machines the best way to 
accomplish bypassing the ISA Server?

  Port 443 is for SSL.  Perhaps the applications communication is encrypted and 
that's why it showed up as 443!

  Hello



  My 1st post.  I have a customer who is running SBS2000, and has ISA enabled.  
They have a custom application that looks like a printer to their local 
computer, but it is actually sending a form via email.  The local ports are 
1214 and 1215, and the remote port is 443 (according to one of the app's tech 
support people, who got this information by running it on his home computer, 
and Norton Internet Security reported it as such).



  I've set up two Protocol Filters allowing 1214 and 1215 to redirect to 443, 
but the error is as follows: "Access Denied.  The proxy server needs 
authentication.  The handle is in the wrong state for the requested operation."



  The application is called MortgageMail by EllieMae, and works with their "The 
Loan Handler" and "The Loan Closer" applications.



  Any help would be greatly appreciated.



  Sean
