Thanks for your detailed reply Stephen...

Are you attempting to connect with ReadyNas remote???

. No - I've never had much success with that, works once and then never again.

if you never get a functional frontview connection to the remote system [from any remote site], you could have a port forwarding problem on the US site's router. And you will also need to configure proper port forwarding for rsync (which router depends on where the backup job is being run).

It starts to load the page but I get only the heading, border colours, & the top 3 buttons (refresh, etc.).

I'm thinking it It wouldn't get that far if the ports weren't mapped properly, but having said that, I can see from the other forums, that many people have had that symptom when they have problems with frontview itself

Maybe you could try making some reasonable size files transfers (either with rsync or FTP), and post the measured transfer speeds and sizes?

I'm not sure how to do that without being able to setup the remote NAS for ftp
