We use the Sonic Wall firewall to control our internet access. The firewall is set up by our admins to block all traffic apart from specified addresses.

We use the Map Point web service to visualise our data but it the firewall appears to be blocking the maps when they are returned to us. If we allow open access through the firewall then the maps work fine.

I have supplied the URL of the Map Point web services to our admins and they have allowed these IP’s through but to no avail. To compound the problem, there is a bug in the firewall’s logging software which is not recording the IP’s of the addresses being blocked! Very annoying!

I was hoping that someone could provide me with a definitive list of addresses that the Map Point web service uses so that we could add them to our firewall.

Can't help you with the MapPoint variant, but at least some of the virtual earth tiles are located at tiles.virtualearth.net (IP 65.55.242.31)

If you install Firefox and Firebug, you can find out all of this if you have the firewall open- it will show you the rendered code and all of the locations and then some

Much appreciated, I'll give the Firefox/Firebug idea a try.

Thanks,
Kevin.
