Wireshark · Wireshark-users: Re: [Wireshark-users] how to filter a port?

["David Drexler" <xxyokc@xxxxxxxxx>]

It's either to or from 'http'.  I also tried 

tcp.port != 80

same results.  I want to run the capture realtime and only see the traffic that interests me.

That's a capture filter to eliminate things on TCP (and UDP) port 80.
Is the HTTP traffic you're seeing on a different port?

If so, you could try a display filter (applied after the capture is
done) like "!http".
