Wildblue Blocked

Hello, I have Wildblue internet service and several times in recent days, while I was browsing the web, it has popped up with the following that appears to imply something out of the ordinary coming from wildblue.com.

Details: Attempted Intrusion "Portscan" against your machine was detected and blocked.
Intruder: wpad.wildblue.com(12.189.32.61)(domain(53)).
Risk Level: Medium.
Protocol: UDP.
Attacked IP: AMD3200(192.168.1.101).
Attacked Port: 2363.

However, while this block is in force, I am unable to access the internet at all, so it would appear to be something necessary to the function of Wildblue. As I am not terribly learned in firewalls and such, can anyone tell me if this is something I should be concerned about? Thanks.
