I am working on configuring an IIS 5.0 FTP server which will exist in a DMZ behind a box running Wingate 5.0.6. Currently, the IIS server is fully functional, but the FTP proxy for it does not seem to be.
The firewall has three NICs in it. One goes to the internal network and two go to the outside. The FTP proxy is set to map port 21 from one of the outside ones to the IIS server on the inside which it seems to do correctly. However, it does not appear to map the ephemeral ports (1024-5000) to that server. Do I need to open that range separately? I was under the impression that the FTP proxy preset would handle that.
