<DIV>DHCP requests are broadcasts that only go out on the interface that
requires DHCP service. If eth0 requires DHCP configuration, but eth1 does not,
then DHCP requests will only go out on eth0. IOW, eth0 will only talk to the
cable modem for DHCP and eth1 will only talk to your internal DHCP server (if
not statically configured).</DIV>
<DIV> </DIV>
<DIV>UNLESS you have dhcp forwarding configured somewhere, which you
shouldn't.</DIV>
