Bug#320492: Differences between dhcp3-relay and dhcp-helper.
A brief summary of the differences between dhcp3-relay and dhcp-helper.
1) Size
/usr/sbin/dhcrelay3 size is 157240 octets
/usr/sbin/dhcp-helper is 9924 octets
2) Kernel requirements
dhcrelay3 needs the Linux Packet Filter Facility available in the
kernel, dhcp-helper doesn't. This allows a smaller kernel.
3) Configuration
dhcp-helper can be configured to forward DHCP requests to whole-network
broadcast, rather than having to know the IP address of the DHCP server.
dhcrelay3 can't. dhcp-helper will work with more than one relay in
series, dhcrelay won't.
In general, dhcp-helper fits better on embedded-router type systems
(which is what it was written for). Embeded Debian is a coming thing.....
HTH
