The http://www.gentoo.org/doc/en/home-router-howto.xml in Code Listing 3.1: Setting up eth1 and Code Listing 3.2: Setting up eth1 the examples are using the old style conf.d/net layout some examples : config_eth1=( "dhcp" ) should be config_eth1=dhcp config_eth1=( "66.92.78.102 broadcast 66.92.78.255 netmask 255.255.255.0" ) should be config_eth1="66.92.78.102 netmask 255.255.255.0 brd 66.92.78.255" not shure about this next one routes_eth1=( "default gw 66.92.78.1" ) should be routes_eth1=66.92.78.1
probably fixed by: http://sources.gentoo.org/gentoo/xml/htdocs/doc/en/home-router-howto.xml?r1=1.65&r2=1.66
