I'm not familiar with how dhcpd will be set up on 6.2, but on 7.2 you can
edit /etc/sysconfig/dhcpd
and add eth1 to your DHCPDARGS so that the server only listens on eth1.
(My whole file reads:
#Command line options here
DHCPDARGS=eth1
)
Same thing as what Mr. Feist told you to do, but if you add it here, then
you don't have to worry about it anymore.
