I am doing some consulting work for a client who has a Firebox III as a firewall. We have normal ports open including 80,21,443,5900,3389 etc. and am able to browse every site known to man however the one thing we can not do is go to mapquest and see a map. The map space loads along with the larger/smaller slide bar on the left side however the map itself never loads. If I connect outside the firewall or from any other site the maps load fine. This is not a browser configuration issues as I use several browsers and they all work outside the firewall. I have opened up UDP ports 20 to 22000 as a test but have been unable to figure out what ports outside of 80 and 443 are needed to make this work.
We can access google maps and all other map site fine - is is only mapquest.

do you have policies in your firewall like restricted site or a list of site that the users are allowed to go can you access this site from the brownser

Thats wierd i just added the site to the list of allowed sites and it times out as soon as i enable all traffic the site work fine.
you can use etheral to see what is trying to access when you type the site on the browser

i dont have my laptop with me but i will test tomorrow and see what ports need to be open im getting ready to give access to my users  and this will be very helpful in the past i have added sites to my firewall and did not work because the page had frames and it was calling a 3rd site to displayed the information it took me a couple of months to figure that out. thats why i asked if you could access the site above i looked at the source code and its pulling images from that site.
