10 Firstly, you really should look at /etc/conf.d/net.example and upgrade your
11 config to the new format.

24 Err, you can't assign the same IP to multiple interfaces.
25 You mention DHCP, did you mean that eth1 and eth2 are to get a DHCP leases

27 config_eth1=( "dhcp" )
28 config_eth2=( "dhcp" )

35 What are you using dnsmasq for?
