Accessing the EX4

I am not sure if there are similar forums but I wanted to see if I can get some recommendations regarding the situation described below. 

I want to be able to access my EX4 files from my work computer but can not install the desktop app! WD2GO doesnt work with the EX4 so that leaves the remote desktop connection web file viewer. While this is an ok method I can not get the IP address to come up with chrome or IE9

Any suggestions?

Direct WebDAV connection would probably be the simplest. 

If you’ve already got port forwarding working, then you do the same thing (with a discrete set of ports) for WebDAV.

But of course, if your work firewall policies block WebDAV (like ours do) then that won’t work.
