Hi Jessica
You could try setting this option to true. Taken from the dhcpd.conf
man page (taken from dhcp-3.1.1, but should be in 4.x):
stash-agent-options flag;
If the stash-agent-options parameter is true for a given
client, the server will record the relay agent information
options sent during the client's initial DHCPREQUEST mes-
sage when the client was in the SELECTING state and behave
as if those options are included in all subsequent DHCPRE-
QUEST messages sent in the RENEWING state. This works
around a problem with relay agent information options,
which is that they usually not appear in DHCPREQUEST mes-
sages sent by the client in the RENEWING state, because
such messages are unicast directly to the server and not
sent through a relay agent.
regards,
-glenn
