Hi,

Thank you.

Although I did not understand your recommendation.

My problem is that for some reason, DHCP server is allocating IP
addresses from the subnet 200.232.140.0 for stations in the
172.16.255.0 segment. I would like to control which addresses
should be given to each segment.

Regards,

Jeff.

The following:

$ sudo tcpdump -i vr0 "port bootpc || port bootps" && tcpdump -i
sk0 "port bootpc || port bootps"

$ sudo dhcpd -vf

$ sudo netstat -tan|egrep -i "67|68"
