![]() ![]() For example, a user could connect by typing in. In order for others users to connect, you would need to provide them with the hostname you created on No-IP. Users can now connect to your server with the username and password you set on your FTP server. This will remove the need for the Dynamic Update Client. Some devices that include No-IP for Dynamic DNS can be Routers or Camera systems. You can see if a device at your network supports for Dynamic DNS updates. This client will check your IP address every 5 minutes and if your IP has changed, it will automatically update your hostname with No-IP. This client will need to be running at all times at the network’s location. You can download our free Dynamic Update Client. If you have a Dynamic IP address you will need to configure a way to keep No-IP up to date with your changing IP address. If you are unsure how to port forward you can review our General Port Forwarding guide. You will need to open and forward port 21 on your router and any firewall you might use. Once the user has been created you can enable the account, as well as set a password for the user(s) you have created under the “Account Settings”, in the “General” sidebar. Enter the username you would like and select the group the user should be assigned to. Once the group has been created you will need to create a user by going to “Edit”, then “Users”, then “Add”. You can now create a group name and set the group permissions. This tells you that FTP is indeed running on port 21 at the given host. If FTP is running as a server on port 21 at, you will get back a status message. To configure the groups in the FileZilla Server go to “Edit”, then “Groups”, then click “Add” under the group window. the telnet command will try to connect to (replace this with the ftp hostname you are trying to connect to) on port 21 (which is the standard FTP port). Once started you can now configure the FTP Server with different groups for the users. If you would like to set an administrative password, enter one now and click “OK”. ![]() Once installed, the FileZilla server should open. If you do decide to change the port, make sure it is an uncommon port, generally 1024-65535. I recommend leaving it at the standard port 14147. You will see an option to select what port the admin interface for FileZilla server should list. You will need to install the FileZilla server on your computer. You’ll first need to download the FileZilla server. There are a few different choices you can use to create an FTP server, but in this guide, we will use FileZilla, which is free. Once you have created a hostname with No-IP you will need to download and run an FTP server. If you do not already have an account, you will need to create an account by following the steps in our Getting Started guide. You can create and use a hostname with No-IP to run an FTP server. ![]() Īlso, I can ping the server from my network, but I can't telnet into it on port 21.FTP or File Transfer Protocol servers allow you to share or host data on your computer that might be too large to transfer through email. Someone mentioned NAT issues - I have several entries like this in the log:įri, 14:10:27. My firewall/router is a Netgear ProSafe VPN Firewall FVS318v3. Does this shed any more light on the problem? I turns out that there were 2 return packets per connection attempt. With source and and destination IP addresses filtered for the FTP server. I've also tested access to other FTP servers (ea.com,, etc.) so I know that port 21 is not being blocked. ![]() Since the ISP hosts the server, I can't restart it, nor do I know what the server software is. They insist that it must be something here at the office that is blocking access. I've contacted our ISP (who hosts the website/FTP server) and they can't find anything wrong on their end. All of the ports that were open when it was working are still open now. I have changed absolutely nothing on our domain controller or our firewall/router. The error message that I always get says that a connection cannot be established, and I am never prompted for my credentials. I can't access the server from any machine on my work network. I can connect just fine from home, or by using an FTP app on my cell phone as long as I'm on the cell network. Ever since then, I haven't been able to connect to the server from work. Last week while uploading website files to our server via FTP, the transfer failed. ![]()
