dhcpd question

[Igor Gueths]

Hi all. I am attempting to configure Dhcpd so I can set up Masquerading on
my box. The only problem is that I can't seem to find how to set the
interface where Dhcpd listens for broadcasts. I read in the dhcp-options
manpage that this can be specified on the command line, however I find no
reference as to what the actual option is. And the man page for dhcpd.conf
doesn't seem to mention it anywhere. The only thing I think I figured out
that its probably a parameter within a subnet declaration? Can someone
perhaps let me know as to what the parameter is? Thanks!
