maps on mapquest not displaying

Does anyone know what port or service that the maps on mapquest use? I have a NetEnforcer in place. When we use mapquest it will not display the maps, just shows a box with a red X. I have contacted mapquest with no response. Any ideas on the port or service would be appreciated.

 

Hey,

Well i just went to mapquest and i checked a few things out. I'm pretty sure that all the information for the page is coming over port 80 which is the typical HTTP transfer port.

The mapquest map is actually a regular .GIF image so make sure your browser or firewall is allowing animations. Also you should check your cookie permissions because that could be the problem also.

Hope this helps
