[Techtalk] Linux gateway + DHCP server setup?

Absolutely.  I'm not sure you can use DHCP to assign a dynamically
addressed router.

Specifically for DHCP, no.  However, in order for your Debian box to
function as an Internet gateway, it must have a default route (all 0's) for
eth0.  If both NIC's are configured correctly, you probably already have
this set up.

> subnet 10.10.10.0 netmask 255.255.255.0 {
>   range 10.10.10.1 10.10.10.75;
>   option broadcast-address 10.10.10.255;
>   option routers dns.test-lan.home.com;
> }

I'm not sure what's causing the error you're getting above, but I would
suggest you only include assignable IP addresses in your DHCP range; e.g.,
10.10.10.10 has been statically assigned to your Debian box so it shouldn't
be part of the assignable address range.

Sorry I can't be of more help.
