Or, the gateway device is not properly set. You should see something
like this in a route -n output:
root@coyote sysconfig]# route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.xx.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
0.0.0.0 192.168.xx.xx 0.0.0.0 UG 0 0 0 eth0
The Flags UG (User Gateway) must be set to both the right Gateway address,
and to the right interface if more than 1 is present.
Neither of the destination or gateway addresses is this box.
In this case the gateway is my firewall boxs eth0, and its Gateway is
set to the address of router, accessable through a different eth1 card,
which handles all the NAT stuffs here. iptables and a few other guard
dogs sit between the ethernet cards.
Commonly, the best way to autograb the right routing is to use a
demand dial script, and start it before bringing up the rest of
the network stuff so it has already established its dibs on the
default routing. If not that, then you'll probably have to jump
through a few extra hoops near the bottom of your /etc/rc.d/rc.local
(redhat nameing unforch, translate to debian) file and add a couple
of lines to play with the routing that will be fubar if eth0 comes
up first. I found it was far less trouble to just start the demand
dial script first as everything Just Works(TM) then.
