I'm setting up a DHCP server that needs to handle the DHCP requests for
various remote network segments. I don't want to have the DHCP server
key off the MAC address of the clients because the client MACs will
change too frequently. Because of this, I'm using the Option 82 setting
from the remote segment router to relay the DHCP requests to my central
I see the DHCP requests being sent to the DHCP server but the server
generates the following error message:
DHCPDISCOVER from 00:00:39:86:0d:a7 via 10.100.52.1: unknown network segment
The IP address 10.100.52.1 is an IP address of the router that is acting
as a Helper Agent.
I've been reading the man pages and using Google, but so far have not
been able to find any examples for this type of configuration. I have
found some references to this as a way that Cable ISPs would configure
the DHCP server for their clients but none have examples.
Any help in locating an example configuration would be greatly appreciated.
