A customer asked me to setup a server SFTP (using openSSH or FreeSSHd). This server passes through a firewall that accepts only port 22 and is connected to just one client. I know it's really weird but they don't want to open other ports on firewall....
Thanks for the help!
The firewall has only port 22 opened
If the client has the source port 7777
How can be possible that the firewall doesn't block the port of the client??
May be the firewall blocks only well known ports?
