Server sitting in DMZ off Firewall on a different network. When one FTPs to it from a machine inside the Firewall, the connection is made and one can upload, download and modify files. When one FTPs from a source on an external network the log in proceeds as it should, but the proper directories are never found, and eventually the connection will time out. The server is Windows 2003 with IIS. The firewall is a WatchGuard Firebox.
I've gone through the server settings and nothing seems amiss there. The FTP rules on the firewall allow both connections from the internal network and any external network.
There are no entries in the log or the Event Viewer to indicate a problem.
Does anyone have an idea how I might go about resolving this issue?
