Hi,

you'd try with this: (not tcp port 80) and (not tcp port  443)

I would like to monitor for a few days anything going out on any port other than port 80 or port 443.  is there a 
simple display filter that I can use to see this information.  I am new and still learning some of the simple stuff.  
The reason for doing this is so that I can right a firewall rule to block all ports but what is needed.
thank you for all the help.
