Re, - Brian -----Original Message----- From: Pearson, Andrew [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 10, 2002 12:38 PM To: '[EMAIL PROTECTED]' Subject: IIS 5 - FTP and smoothie Hi all, I have a small problem with my network, i wondered if anyone has any suggestions. The problem lies with my IIS 5.0 server which is sitting behind a SmoothWall Firewall box. When I FTP to the server while on the inside of the network, I get a connection. And when I do a GET or a DIR then I recieve the proper response with a file or directory listing... Now, when I access the server from the outside of the network through smoothwall, I still get a connection to the server, but this time, whenever I try a DIR or GET, the session freezes and I have to kill it. My initial guess is that Smoothwall is allowing a connection through port 21 (which I've allowed access), and I recieve the connection response. But the FTP server is then switching ports to 2500 or something similar for data transfer... which I cannot open on smoothwall because the port number changes... Has anyone dealt with this before? I've searched on Google to no avail, and also posted on the Smoothwall IRC channel with no success either... Thanks. Andy. Andrew Pearson Consultant ADC Software Systems Division
