Since watching pftop has become my favorite pastime :) I have a question:

I see frequent inbound icmp from and to ports 256, 512, 768 and 1024 (and
occasionally other ports). I've googled this, but got nothing useful.
What's this traffic all about anyway?

my pf.conf file has a rule to pass required ICMP traffic:

pass in inet proto icmp all icmp-type $AllowIcmpIn keep state

where AllowIcmpIn="echoreq"

Thanks,
Jay
