Hi Patrick, CB,
You could also ask them to open up port 5800 and map it to the right IP
address. I suggest that your network folks might be as comfortable opening
up this port and pointing traffic to a specific IP address as port 80 as '80
is such a commonly open port. At least, from what I can see in your note,
there isn't a *technical* reason, afaik.
