Hi Nick,

I followed your advise but it didn't work out. This are the content of the files where I try to set the default gateway:

/etc/rc.local

ip route add default via xxx.xxx.xxx.xxx dev eth2
touch /var/lock/subsys/local

/etc/sysconfig/network-scripts/route-eth2

default via xxx.xxx.xxx.xxx

/etc/sysconfig/network

NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=gw1.mynetwork.net
GATEWAY=xxx.xxx.xxx.xxx

I don't think it has something to do but the eth2 doesn't have an ip assign to it

/etc/sysconfig/network-scripts/ifcfg-eth2

DEVICE=eth2
BOOTPROTO=none
HWADDR=00:15:17:3a:fa:be
ONBOOT=yes
TYPE=Ethernet

Thanks for your help.

Hi,

I'm trying to configure a high availability router for my internal network. I'm able to set both private and public ips on eth0:0 and eth2:0 respectively with heartbeat. The gateway is configured using the /etc/sysconfig/network file (using centos 5.2)

NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=gw1.mynetwork.net
GATEWAY=xxx.xxx.xxx.xxx

but for some reason it doesn't persists when I reboot the server. I have to manually use the route command to restore the default gateway

route add -net 0.0.0.0 gw xxx.xxx.xxx.xxx

I've also tried to set up the route in "/etc/rc.local" and in "/etc/sysconfig/network-scripts/route-eth2" files with no success. I know that this is not a heartbeat related problem but I've tried to google this with no success, so any help on this issue would be greatly appreciated.

Thanks in advanced,

Gabriel.
Have a look at the ip comand (ip route in specific), and add instead of all those lines add:

default via xxx.xxx.xxx.xxx

in the route-eth2 file.

ip is much simpler, and if you ever decide to do policy based routing, much more powerful.

Nick
