Wireshark · Wireshark-users: [Wireshark-users] port monitoring

[mike dodson <mikejd208@xxxxxxxxx>]

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.
