I don't bother with pppoe because the router-modem should give you a generic ethernet interface with a static IP address. I don't bother with dhcp either. You can get by with a static RFC1918 IP address from the modem. My ADSL router modem has address 192.168.123.254 and this PC has 192.168.123.249. My /etc/conf.d/net started out as... config_eth0=( "192.168.123.249 broadcast 192.168.123.255 netmask 255.255.255.248 mtu 1454" routes_eth0=( "default via 192.168.123.254" ) You can get more sophisticated. Currently, I'm at... config_eth0=( "192.168.123.249 broadcast 192.168.123.255 netmask 255.255.255.248 mtu 1454" "169.254.1.3 broadcast 169.254.255.255 netmask 255.255.0.0") routes_eth0=( "default via 192.168.123.254 metric 2" "192.168.123.248/29 via 192.168.123.254 metric 0" "169.254.0.0/16 via 169.254.1.3 metric 0" ) By setting the default route to metric 2, and the other routes to metric 0, my PC can talk to other devices here at home *WHILE THE DIALUP MODEM IS CONNECTED TO THE NET*. My backup PC is on 192.168.123.248/29 and the HDHomerun TV tuner sitting in the living room (facing the CN Tower and Buffalo) is on 169.254,xxx.xxx at the other end of a 50-foot ethernet cable. -- Walter Dnes <waltd...@waltdnes.org>
