Q re dhcpd.conf setup

[A.Fadyushin at it-centre.ru]

Yes, you can give clients the address of gateway via DHCP. The necessary
option in dhcp configuration is called 'routers'. You should put in the
dhcpd.conf file (usually in the subnet definition) the following line

option routers <gateway_address>;

Change the '<gateway_address>' with the address of your gateway. If yor
network is complex and includes more than gateway for the client, list
on that line all the gateways addresses separated by commas (see the
description of this option in 'dhcp-options' manpage).

The dhcpd server does not support the client authentication at this time
(howewer, it may support it in the future). You could try to make
something similar to protection you need using dhcpd's ability to
include conditions in its configuration (see 'dhcpd-eval' manpage).
