I'm trying to make use of Wireshark 1.10.6 for Windows and I want to only capture the traffic to port 443 (to diagnose some weird HTTPS problems I'm having). So I open Capture -> Capture Filters... and in there I delete all filters and then add one filter with filter string set to port 443. Then I start the capture and see that there's a lot of unrelated stuff captured, for example this one
BROWSER 243 Host Announcement , Workstation, Server, SQL Server, NT Workstation, NT Server, Backup Browser, DFS server
so it looks like the capture filters are ignored.
What am I doing wrong and how do I make use of filters?
