I setup multiple IP's on my CentOS Linode with a static configuration for eth0 and eth0:0. From the box itself eth0:0 responds to ping or http requests. Externally, I can not ping the new IP and I can't ping out either.

It appears to me that I need to add a second gateway or route. I tried a GATEWAY statement in ifcfg-eth0:0 and it did not help.

I would like to point out that eth0 is working fine.

Any suggestions?

Here are my IP's from the Linode network page:

eth0: 74.207.242.xxx ( lixx-xxx.members.linode.com )

eth0: 173.230.152.xxx ( lixxx-xxx.members.linode.com )

Gateways: 74.207.242.1

173.230.152.1

Netmask: 255.255.255.0

DNS Servers: 74.207.241.5

74.207.242.5

My primary IP before adding the second IP was 173.230.152.xxx. It is still eth0 in the static configuration.

## File ifcfg-eth0

DEVICE=eth0

BOOTPROTO=none

ONBOOT=yes

IPADDR=173.230.152.xxx

NETMASK=255.255.255.0

GATEWAY=173.230.152.1

##File ifcfg-eth0:0

Configuration for eth0:0

DEVICE=eth0:0

BOOTPROTO=none

ONBOOT=yes

IPADDR=74.207.242.xxx

NETMASK=255.255.255.0
