To show all dns traffic passing through a Portmaster (but not coming from
the Portmaster!)

Add a filter:

add filter dns
set filter dns 1 permit 0.0.0.0/0 0.0.0.0/0 tcp dst eq 42
set filter dns 2 permit 0.0.0.0/0 0.0.0.0/0 tcp dst eq 53
set filter dns 3 permit 0.0.0.0/0 0.0.0.0/0 udp dst eq 53
save filter

Then watch for "hits" on the filter:

ptrace dns extended

When you are done:

ptrace
del filter dns
