Access to bing maps via Excel 2013 with PowerView blocked by fw -

here problem.

i have client uses plug-in powerview through excel2013 .

at origin client hadn't @ access our firewall blocking access office365 ip , bing.com.

once flow authorized on firewall, don't have error message nil happens.

when seek access bing.com/maps map cannot displayed @ same moment did verify firewall , see machine tries access akamai ip(same thing when goes through powerview) . every time tries access bing maps have random akamai ip adress , blocked firewall.

the thought authorize flow towards bing maps , not destination.

so question is, there way larn url uses powerview authorize them on firewall? ever had such problem?

ps solution can imagine moment, impossible our datacenter provider, implement proxy server.

bing maps has long list of ip address ranges need allowed through firewall. contact back upwards team using online form under developer back upwards section here: http://www.microsoft.com/maps/licensing/licensing.aspx able provide list need.
