I know this is a pretty frequently-occurring newbie question but I just haven't been able to find a clear answer for my exact problem on Debian (lenny). I have two NIC's on my linux box. eth0 is connected to a router, which is connected to the Internet. eth1 is connected to a set of other linux boxes via a separate switch as a private network (which is to function as a Sun/Oracle Grid Engine cluster), and these linux boxes do not need Internet access.
The router is 192.168.1.1, so I set eth0 as 192.168.1.200 (there are a bunch of Windows PC's connected to the router, e.g. 192.168.1.100, 192.168.1.101, etc.), and eth1 as 192.168.2.1 so that the private network will have address 192.168.2.x (the other linux boxes connected to the switch are 192.168.2.101, 192.168.2.102, ...) My /etc/network/interfaces file looks like this: =============================== # The loopback network interface auto lo iface lo inet loopback # The primary network interface allow-hotplug eth0 #iface eth0 inet dhcp iface eth0 inet static address 192.168.1.200 netmask 255.255.255.0 broadcast 192.168.1.255 gateway 192.168.1.1 dns-domain lan dns-nameservers 192.168.1.1 allow-hotplug eth1 iface eth1 inet static address 192.168.2.1 netmask 255.255.255.0 gateway 192.168.2.1 =============================== The "route" command gives me this ("amade" is the name of the linux box): =============================== Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.2.0 * 255.255.255.0 U 0 0 0 eth1 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 default amade-eth1 0.0.0.0 UG 0 0 0 eth1 =============================== What am I doing wrong here? One problem is that sometimes the "route" command gives me something like: =============================== Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.2.0 * 255.255.255.0 U 0 0 0 eth1 192.168.1.0 * 255.255.255.0 U 0 0 0 eth0 default amade-eth1 0.0.0.0 UG 0 0 0 eth1 default 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 =============================== in which case the linux box cannot access the Internet, because "amade-eth1" seems to take precedence over the router as a gateway to the Internet, which of course will not work.
