[NTLUG:Discuss] Connections using aliased IP addresses instead of the primary one

[Neil Aggarwal]

Hello:

I have a machine where I set up two IP aliases
on eth0 by copying 
/etc/sysconfig/network-scripts/ifcfg-eth0
to 
/etc/sysconfig/network-scripts/ifcfg-eth0:0
/etc/sysconfig/network-scripts/ifcfg-eth0:1

and changing the relevant IP info for new IP address.

Unfortunately, now I am seeing outbound connections
failing at my firewall from services like NTP, etc. 
since they are now using a source address
from one of the aliased IP addresses instead of the
original eth0 IP which is allow through the firewall.

I don't want to have to keep maintaining 3 copies
of each firewall rule to accommodate the new IP 
addresses.

Is there a way to tell the machine to use
the eth0 IP address as the source address for
connections?

Thanks,
	Neil
