Sorry, I guess didn't give enough info. My BB is thru Alltel and it's not on a BES. My company doesn't have a BES. So my data connection (thru Alltel) must enter my corporate network from the outside. At this point, the only outside connections into our network are via VPN.

I guess the next question is: does my BB have a specific IP address on Alltel's network? If it does, my WAN admin could open our firewall to that address. But I'm betting my BB's address would be an internal Alltel address, so the admin would have to open the firewall to a range of Alltel's external addresses. I know the admin won't do that. Hmmm....
