Ill throw in some info on getting my Vantage working remotely. These strings were added to my 46xxspecials.txt. Note there are two sets, one for Equinox and another for Vantage. the IP address in SET USER_STORE... is the external address (WAN) of my IP Office.
Also, at my remote office, I setup hfs.exe on my laptop with a static address. I entered my laptop address in the http server in IPO > System. This HTTP server MUST be something other than the IPO for Vantage to work. The 46xx....txt files go into IPO, and the big .bin files go into hfs on the laptop.
SysMon helped me tremendously. Enabled FileSys in tracing options and look to see what the Vantage is looking for and move the files until you get it right.
At the bottom is the command for the background image, I haven't played with that yet.
Hope this helps someone in the future.
