Yes, thank you very much - SSH works perfectly. In addition, FTP works as well. I have both locked down to only allow connections from the local network. The reason why we need FTP working is because we run cron jobs from our main server to automatically update several files on our website. We also connect via FTP to the web server via DreamWeaver to make changes to our website.
Now here's how I fixed FTP...............Previously we had this in gateway mode and there was a port forwarding rule set up for FTP to another server on our network and when I changed this from a gateway to server only....the port forwarding rules remained intact, but I couldn't change or remove them. After I upgraded, I could and did remove them and bam, FTP works again.
