Hi all,

I draw my configuration of ethernetcards:

PC (eth0 10.0.0.1)-->3com switch-->speedtouch(10.0.0.138)-->theNet
PC (eth1 192.168.1.10)-->FSG (192.168.1.1)-->speedtouch(10.0.0.138)

I apologize, there is one small inacuracy in the second line. It should
read:

PC (eth1 192.168.1.10)-->FSG (192.168.1.1)-->3com
switch-->speedtouch(10.0.0.138)

The WAN port of the FSG is unused. It is connected to the 10.0.0-network
through the 3com switch.

Remove any GATEWAY settings in /etc/sysconfig/network-scripts/ifcfg-*
and add to /etc/sysconfug/network:

GATEWAY=10.0.0.138

Hi Paul and Craig (who gave the same advice),

I did what you said and nothing changed. The resulting route was:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
10.0.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth1



The contents of /etc/sysconfig/network is:

NETWORKING=yes
HOSTNAME=athene
GATEWAY=10.0.0.138

The contents of /etc/sysconfig/networking/devices/ifcfg-eth0 is:

DEVICE=eth0
ONBOOT=yes
IPADDR=10.0.0.1
NETMASK=255.255.255.0
METRIC=1
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes
BOOTPROTO=none

The contents of /etc/sysconfig/networking/devices/ifcfg-eth1 is:

DEVICE=eth1
ONBOOT=yes
IPADDR=192.168.1.10
NETMASK=255.255.255.0
METRIC=10
TYPE=Ethernet
USERCTL=no
IPV6INIT=no
PEERDNS=yes
BOOTPROTO=none

The route I need to end up with is:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use
Iface
10.0.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 0.0.0.0 10.0.0.138 0.0.0.0 UG 0 0 0 eth0 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth1

where the last line is probably unnecessary.

Is this after a reboot? I don't see where this default route is coming from for a fresh boot.

If you change ifcfg-eth1 to have ONBOOT=no, what happens?

You can add NOZEROCONF=yes to /etc/sysconfig/network to get rid of the 169.254.0.0 route if you don't want that one.

Paul.
