Re: DHCP for 2 networks

[Thomas Cook <sysadmin@black-gear.com>]

First, thanks for the kick in the head Cristian.

Second, Simon, thanks for the help.  In the dhcp init script, does the order
of the "eth2 eth1" stuff correspond to the order of the subnets in the
dhcp.conf file?  I.E. In your example eth2 is for 192.168.1.x and eth1 id
192.168.2.x?

Thanks,
-Tom
