We have an internal web server and Web page, that has links to forms
located on an FTP server , run by the State. Users are reporting from
inside the firewall, that when attempting to access the forms they recieve:


################################################## #########################

HTTP ERROR
Status : 504 Gateway Time-Out


Description : Unable to connect to origin Web server.


Note : If necessary, please contact your Systems Administrator for
resolution.

Users outside the firewall, report no problems.
These are just hyperlinks to PDF files that reside on The states FTP
server.When I unload ipflt, internal users can access the docs no problem.
The stateful exceptions for http traffic 80/443 are in place, as are the
execeptions for stateful FTP. We are using Http proxy and Http
acceleration. Its defintely a filtering issue however. Any Idea what I may
be missing here?
