Try emerging 'iproute2' (if not already installed) and then adding the
following line to /etc/iproute2/rt_tables
1 altlan
and then using the following in /etc/conf.d/net
modules-"iproute2"
config_eth0=( "77.xxx.104.14/24" "77.xxx.104.100/32" "77.xxx.104.101/32"
"77.xxx.105.100/24" )
routes_eth0=( "default via 77.xxx.104.1"
"default via 77.xxx.105.1 table altlan"
"77.xxx.105.0/24 table altlan" )
rules_eth0=( "from 77.xxx.105.100 table altlan" )
postup() {
# This function could be used, for example, to register with a
# dynamic DNS service. Another possibility would be to
# send/receive mail once the interface is brought up.
# Here is an example that allows the use of iproute rules
# which have been configured using the rules_eth0 variable.
#rules_eth0=" \
# 'from 24.80.102.112/32 to 192.168.1.0/24 table localnet priority

priority 100' \

eval set -- $\rules_${IFVAR}
if [ $# != 0 ]; then
einfo "Adding IP policy routing rules"
eindent
# Ensure that the kernel supports policy routing
if ! ip rule list | grep -q "^"; then
eerror "You need to enable IP Policy Routing
