Routing problem?
Burke, Thomas G.
memory here...
2 3c509 ISA ethernet cards
eth0 is 192.168.68.1 - (obviously) internal network
eth1 is connected to a cable modem - I have asked for a static IP
I set aside an old 486 for the setup when the modem was installed... When
the guy connected it to the network, it discovered it's own IP address,
gateway, netmask, all that rot. I copied it all down to use the linux
server.
Now, on the linux server, I have set all this stuff up, & I see a couple of
problems, all of which seem to be related to routing (but I could be
wrong)...
the route command does _not_ show a default route - when I try to set it (to
either the gateway address or my IP address), it still does not work.
When I try to ping eth0 (by addr or IP), I get nothing back. If I ping a
machine on the internal network, however, I get responses & the internal
network can see the server just fine.
When I try to ping eth1, I get the same results. I have, as yet, had no
luck contacting anything on the outside world.
Any clues?

Are you using pump(8)? If you edit the
/etc/sysconfig/network-scripts/ifcfg-eth1 (or whatever)
script and add in a "BOOTPROTO=dhcp" line, then pump will set up
the lot for you (including DNS and gateway). Works fine for my
cable modem (RoadRunner).

networking in control panel, & it appeared to have failed... I will try
again tonight, & see what happens.
I remember that someone else has mentioned ppoe? I could use a quick
tutorial in that, as well, if it's likely to be in use here...
Oh, did I mention - I'm using cablespeed.com

pppoe is for ADSL connections. You can do a "man -k pppoe" to see
the man pages.
Are you certain both ethernet cards are showing up? What does
"ifconfig -a" show? Does "dmesg" show both ethernet cards?
Here's my setup on a RoadRunner system:
/etc/sysconfig/network-scripts/ifcfg-eth0:
DEVICE=eth0
BOOTPROTO=dhcp
ONBOOT=yes
/etc/sysconfig/network:
NETWORKING=yes
HOSTNAME=localhost.localdomain
On boot, pump fires up and brings up the interface with no problem.
Of course, your mileage may vary. Oh, this is a RH 7.1 system with
a 2.4.7 kernel, but it worked with 7.0 and 6.2 out of the box, also.

Well, give that stuff a shot and if you can, let us see the printouts.
