FTP behind a router with Windows XP Professional FTP Server
I have been using a the FTP server running on Windows XP Professional with a
static IP for years with no trouble. I have recently added a router as a firewall and port forwarded port 80 for the web server no problem there and port 20 & 21 for the FTP server. I don't think I have all of the necessary ports open to allow file transfers. I keep getting permission errors. You can get a connection but transfers fail. Has anyone set this up before without opening so many ports that the firewall is useless. Is the version of IIS released with Windows XP Professional capable of assigning ports for these transfers I understand you need 2 ports per connection. Any help with this problem would be appreciated. -- Al |

FTP behind a router with Windows XP Professional FTP Server
Hi Jack
The article was helpful I tried setting the passive range both ways and the range used by the XP FTP server did not seem to change. Maybe the FTP server in XP is limited. I tried another FTP server (GuildFTP) and it will let you change the passive port range in the application settings. The only thing is it won't let me shorten the port range down as small as I would like. As long as there are not two many connections I can still limit the range on the router. I can set the start of the range used and just open as many as I think I need. Thanks, -- Al "Jack (MVP-Networking)." wrote: Hi FTP server can work in Passive or Active mode.
