1. NEWBIE: Routing problem with extra default route
I'm using Redhat 7.0, with Kernel 2.4, on a box that I'm using as a masquerading
firewall, dhcp server, dns server etc..
The problem I have is that both network interfaces are adding a default route,
when I only want one of them to. As the machine is the gateway to the Internet,
I want only the external interface to add a default route when the interface is
The current situation is causing me problems with ipwatch, that do not occuer
when eth0 has no default route attached (I think it is a problem with trying to
ping a server over the Internet, through the wrong interface?)
I can remove the unwanted route with a "route del ...", but as soon as I
"ifdown" the interface, and then "ifup" it, the route reappears. Where do I
modify the network scripts to tell the machine not to set a default route for
I've looked in sysconfig/network-scripts, but no joy so far.. although I think
it may have something to do with the contents of /etc/sysconfig/network ? There
is a GATEWAY declaration in there that matches the Gateway setting for the
unwanted route - but I can't find anything in the man pages that explains this
Thanks in advance,
