[AG-TECH] macbook pro video (vic) troubles

[Enrique Terrazas]

Hi,

I'm having the same problem in a firewall situation myself.  In the  
VIC window I can see the port assigned and verify that it is within  
the allowable range on the firewall.  From the explanation below, it  
would appear the the port on the VIC window is the sending port.  Is  
there an easy way to verify which is the receiving port to make sure  
that it is within the allowable range?
