        Hi,

        Teamviewer uses this port by default: TCP / UDP 5938, if this port is not usable it switches to 443 (or last but not least http 80) - so manipulating ports is not really a viable option.
        (you cannot block on these ports 443/80 😉 )

        On IP basis, the situation is no easier and difficult to follow (known IP ranges):

        178.77.120.0/25
        159.8.209.208/28
        92.51.156.64/26

        perhaps the best method: blocking DNS queries for *.teamviewer.com (with pfBlockerNG)

        Cats bury it so they can't see it!
        (You know what I mean if you have a cat)
