It is much easier than you think.
/etc/conf.d/net
iface_eth0="123.456.789.123 broadcast 123.456.789.255 netmask 255.255.255.0"
iface_eth1="192.168.123.456 broadcast 192.168.123.255 netmask 255.255.255.0"
gateway="eth0/inter.net.gate.way"
Change the above according to the IP config you want, copy /etc/init.d/
net.eth0 /etc/init.d/net.eth1 and your done.
For the specifics:
The first address should be the ip you want to assign to the device.
The netmask is used to specify what logical network you are part of.
The broadcast address is the logical NOT of the netmask OR'd with the ip
address.
An entry is automatically added into the routing table via each device for the
network that device belongs to (ip address AND'd with netmask)
Although the 192.168.x.x range is a class B subnet, it has been set aside for
class C subnets hence a netmask of 255.255.255.0.
