Filter out all traffic NOT going to/from the endpoints (and servers like

gatekeepers) using a capture filter.

ip hst 192.168.11.4 or ip hst 192.168.11.5 or ip hst 192.168.11.1

Or something like that, creating capture filters is not my hobby ;-)
A couple of more suggestions:
- Filter out all non tcp or udp traffic
- filter out all non ethernet traffic
