UDP Blocking Firewall

Hi,

 

When i run the SIP COMMUNICATOR application, i got "UDP Blocking Firewall" .. when it is trying to connect with STUN Server..

It doesn't get any response from the Test I..

 

how to overcome from the "UDP Blocking Firewall"..

here, i placed a portion of output what i got when i ran the application..

--------------------------------------------------------------------------------------------------------------
