Open SFTP on my XG Firewall from within my network

I have a client which we need to connect via SFTP on port 22 (via Filezilla) to his server which he has given us the IP address (as the host).

He has also accepted on his server our Public IP to be able to connect to his server via SFTP. 

I have added a firewall rule on Sophos for my network to be able to be able to SFTP to this , as well as any VPN users to SFTP out but still it cannot connect. 

Am I opening the port correctly for SFTP (see screenshots below)
