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.
