Connect connect to our internal server via SFTP - Cisco RV220W router
We just installed a new RV220W router in our office and I'm having a hard time setting it up.
We have an internal server for web development. It is setup to only allow SFTP connections using port 2211. I can connect to the server locally using the IP address, but if I try to connect to it from outside of our office network, the connection is refused.
I've added an Access Rule for SFTP, and setup a port trigger:
Outgoing Ports: 2211/2211
Incoming Ports: 22/22
I've also tried reversing the Outgoing and Incoming ports, but every combination of 2211 or 22 that I have used results in a refused connection.
What am I missing or doing wrong? Is there another firewall setting that I need to change to allow remote SFTP access to our server? I shouldn't need to change anything in the server because it worked with our old router.
You shouldn't need any kind of port triggering. Just forward 2211/tcp to the server in question. SFTP uses only a single port for all connectivity (FTP is tunnelled inside of SSH) and doesn't need anything more than this:
Incoming port should be 2211/tcp, outgoing ports should be any.
