Hello
I've a problem with first rule in traffic shaping 
ipfw show looks like: (my lan net is 10.1.1.0/24 router IP: 10.1.1.1)
50000   2119579    311712547 allow ip from 10.1.1.1 to any
50001    277318     20537807 allow ip from any to 10.1.1.1
50002     41839      6541827 pipe 3 ip from any 53 to 10.1.1.0/24 out via xl0
50003     45578      3192989 pipe 7 ip from 10.1.1.0/24 to any dst-port 53 in via xl0
50004   6054884   4211475062 queue 2 ip from any 4661-6348 to 10.1.1.0/24 out via xl0
50005   5837266   1393196924 queue 7 ip from 10.1.1.0/24 to any dst-port 4661-6348 in via xl0

Please tell me what is it rule 50000 and 50001 whats does mean?
rule below 50001 is't looks good but I don't undestand firts rule ?
10.1.1.1 to any and any to 10.1.1.1 I didn't set rule like this ...
it's from firewall maybe ?
If it's wrong please tell how to correct this.
