	Sorry, I have forgotten last line of /etc/ntp.conf:

restrict 192.168.0.0 mask 255.255.0.0

	I have notice a minor issue. To show traffic activity, I have to check
UDP/123 on wm3 and wm4 as lagg0 doesn't show all packets. Example:

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on lagg0, link-type EN10MB (Ethernet), capture size 262144 bytes

tcpdump -i lagg0 seems to only print incoming packets.
