How to enable FTP Port 21
I am trying to port forward a server using my public ip, but it doesn't work. Using a local host works, but when I try to scan my public ip, it says: "99.51.65.59 isn't responding on port 21 (ftp...
So, you used the Advanced tab on the Orbi web interface, selected Advanced Setup->Port Forwarding, and then entered the IP address of the FTP server on your internal network. Correct?
yes
Sorry, I neglected to ask about how the Orbi is connected. Sometimes the internet modem is actually a "modem/router", which results in what people call a "double NAT". The Orbi may have forwarded port 21, but the modem/router which is in front of the Orbi may not have.
What happens when you do a trace route to 8.8.8.8?
i.e. open a Windows command window and type "tracert 8.8.8.8"?
The first line should be the Orbi itself, usually 192.168.1.1 The second line should be a "public" IP address, that is NOT a "192.168" or a "10.x"
- Instead of port forwarding port 21 which is used by Orbi, please port forwad one of the free ports like 8121 to port 21 on the target device, and then use your public IP and port 8121 to connect remotely to port 21 on the target device
