Cannot open port 21 for ftp but port 22 is ALWAYS open

I have been unable to open port 21 on my Belkin router but find port 22 is always open even though the port forwarding page says it isn't.

How to setup a virtual server on router

Virtual Server, also referred to as Port forwarding or port mapping can be setup with the router.

The setup of the virtual server depends on what you want to setup.

Virtual server is used to allow computers not on your internal network or computers on the internet to access a resource or service on the internal network.

For example:

Say you have an FTP on your internal network that you want people on the internet to access. To set that up go to the virtual server screen on the router and specify the IP address of the computer on the internal network that has the FTP server on it. The private port that you want to specify would be 21 because port 21 is FTP. The public port could be any number you want it to be, for ease of explanation lets just say it is also 21, that is the port the public would use to access the machine. For a computer on the internet to access the FTP server on the internal machine they would open up a web browser and type FTP://(WAN IP ADDRESS, found on main status page of router screen):21.

A better example would be FTP://

Some times you will need to open the Logical Ports on the router.
These are the logical ports.
For this you will need to open the set up interface of the router.
Once you open the set up interface of the router, you will be able to find the settings on the router where you can open the ports for the particular program.

If you are opening the ports for a special device in your network, then you must know the IP address of that device.
For example, wireless camera, DVR, X-box, Play station ...
You can choose the option PORT FORWARDING for a special device application.
If you just want to open the ports for all the network, then you can choose PORT TRIGGERING

For example ,
You have a Linksys wireless router and you want to open the ports for the X-box.
You have opened the set up interface of the router. You will see Application and Gaming TAB at the top.
If you click on that tab you will find different Sub tabs.
Click on Port Triggering => Here you can open the port numbers for the network.
Click On Port forwarding if you want to open the ports for a special device in the network.
Click Save settings once you open the ports on the router.

Some of the recommended port numbers for different applications :

IMAP ==> 143 SMTP : 25
HTTPS ==> 443 HTTP : 80
DNS ==> 53 FTP : 21
SNMP ==> 161 TELNET : 23
XBOX ==> 53, 80-88, 3074
PS3 ==> 80, 443-447 ,5223, 3478-3479, 3658, 10070-10080.
WII ==> 28910, 29900, 29901, 29920, 80, 443
VPN ==> 1723, 500, 443-447, 10000-20000
World of Wars ==> 3724, 6112, 6881 - 6999

Unable to ftp from outside of the network. Went through all of the port forwarding setup. Still can't connect.

You need to setup a Port Forwarding / Virtual Server (FTP) in the router to forward port 21 (FTP default) to your FTP server's FTP port. You may need to setup a reserved IP address for the FTP server first in the router before the option comes up.

Cannot upload pictures to an ftp site

You would open ports 20 and 21, and that would allow FTP transfer in passive mode. (Windows DOS FTP client does NOT do passive mode - so don't use that for testing)
