Gateway Default Route Question

I have a Linux firewall with two etherenet interfaces and one ppp interface.

eth0: Internal network, no gateway set
eth1: Internet, no gateway set and gateway not needed
on this interface
ppp0: Roaring Penguin pppoe through eth1, gateway set
via "/etc/rc.d/init.d/adsl start" which reads
/etc/ppp/pppoe.conf

I haven't found documentation on how to configure the default route on a
gateway. Is it correct that eth0 needs no "GATEWAY=x.x.x.x" entry in
/etc/sysconfig/network-scripts/ifcfg-eth0.

Paul Lutus: Please do not reply.

Thanks,
Hank

An Internet connection using pppd or pppoe usually requires that there
is no default route already set. Pppd - used by pppoe, see man pppoe -
doesn't set a default route, even with the defaultroute option (see man
pppd) present, if one already exists. You don't need a default route
to a single LAN anyway.

Thanks for the information. That definitely helps.
