ISA 2006 blocking FTP traffic
October 18th, 2009 | 
Author: My clients on my network could access FTP servers behind our ISA 06 firewall but they could not create or delete anything on that FTP. I checked to make sure the permissions on the FTP were setup correctly. I narrowed it down to ISA blocking Incoming FTP traffic coming back from the FTP servers. I did some searching and there are many issues out on this. Others issues vary slightly but I did find something that worked for me. I setup the below rule on ISA.
The target principal name is incorrect.
The Issue:
We requested a new certificate for our website from a CA. We applied the certificate on the Internal IIS6 web server. I then exported the certificate including keys and imported onto our ISA 2006 firewall.
I then went into the publishing rule for our website and updated it with the new certificate.
When external users went to our website using https they got the following error:
Error Code: 500 Internal Server Error. The target principal name is incorrect. (-2146893022)
