How to change FTP-server port.

[Laurijan]

Hi!

I use a program called "home ftp server" because it quite easy to use but I get an headache when it comes to the port settings.
There is a setting for server port and data port. Server port is by default 21 and data port 20. When I use a FTP client (winscp) the port setting there is by default 22.
Why can I connect to the FTP server thru the client when the port setting there (client) is a number higher than 21. And why is it that when I change the server port setting in (home ftp server) to lets say 1334 and the client port the 1335 it doesnt connect (connection timeout)

Thanks in advance

Are you connecting via the internet or locally? ie it might be a closed port on a router/firewall.

First I start the no-ip client (for the ftp-server adress).
Then I set up the ftp-server (adress and ports) and start the server on my PC
Third I start the client (winscp) on my computer and try to connect to the ftp server adress
I got Sygate personal firewall and Nvidia Nforce 4 firewall active while trying this

its either 1 your modem, 2 your router, or 3 you havent done port forwarding in norton and also you need too. do you have dsl or cable internet, if you have cable than its not the modem blocking the port, but if you have dsl you will have to go into the modems firmware and change the ftp port settings in there

and trust me on this :-D its my damn job, of which im currently at which fucking sucks because its thanksgiving and i could be getting drunk.

I got an 10Mbit/10Mbit VDSL (PPPoE) internet connection, the modem is a 4 Port 10Mbit Cisco 585LRE connected to a switch - from there 4 PC can be connected to the internet while remaining a 100/10Mbit home network. The switch is because the modem can only provide a 10Mbit home network. Furter one RJ45 cable from the switch goes upstairs where my room is and is connected to a A-Link RR24AP ADSL2+, 4-port router (54Mbit WLAN) which funktions as a hub because upstairs my PC and my neighbors one are connected to the internet by wire not WLAN. The RR24AP is factory default settings, the switch has no firewall and the firewall in the Cisco modem (if there is any) can not be acessed - as far as I know. The 2 firewalls on my PC were turned of when I tried to connect to the Ftp server.

Ps I enabled Port forwading for FTP in the RR24AP but it didnt help

So you're basically trying to connect to your external IP from your internal network. That won't work, either connect to your internal IP or have someone from outside of your network try.

But why can I connect to my external ip from my internal ip when the server port is 21 and the client port is 22 - this I usually do to test the server - there are only problems when I try to change the ftp server port and the client server port

Problem solved

Somehow the FTP-Server now workes over port xyz. Dont ask me why its not accepting connections over port 21/22 anymore. Maybe the portforwaring in the RR24AP did help. But I just had to reboot or something.
