I use iproute for it, It allows a 'professional' way to specify routes.
Here is how I get off the LAN (171.68.128/24)
=========================================================================
#!/bin/sh

# loopback device
ifconfig lo 127.0.0.1
iproute add 127/8 dev lo

# ethernet device
IPADDR=171.68.128.13
NETMASK=255.255.255.0
BROADCAST=171.68.128.255
ifconfig eth0 ${IPADDR} netmask ${NETMASK} broadcast ${BROADCAST}
NETWORK=171.68.128/24
iproute add ${NETWORK} dev eth0
DEFAULT=0.0.0.0/0
GATEWAY=171.68.128.1
iproute add ${DEFAULT} gw ${GATEWAY} metric 1 dev eth0
=========================================================================
Note the $DEFAULT which was 0.0.0.0/24 when I used
=========================================================================
#!/bin/sh

ifconfig lo 127.0.0.1 netmask 255.0.0.0 broadcast 127.255.255.255
route add -net 127.0.0.0 netmask 255.0.0.0 dev lo

IPADDR=171.68.128.13
NETMASK=255.255.255.0
NETWORK=171.68.128.0
BROADCAST=171.68.128.255
GATEWAY=171.68.128.1

ifconfig eth0 ${IPADDR} netmask ${NETMASK} broadcast ${BROADCAST}
route add -net ${NETWORK} netmask ${NETMASK} dev eth0
route add default gw ${GATEWAY} netmask ${NETMASK} metric 1
=========================================================================

For one reason or another this did not work.
