Hi,
If you are having problems with DHCP then why not set eth1 to a static IP?
auto eth0
iface eth0 inet static
address 192.168.0.1
netmask 255.255.255.0
auto eth1
iface eth0 inet static
address 192.168.1.2
netmask 255.255.255.X
gateway 192.168.1.1
I usually don't set a gateway to the LAN interface in the settings.
