Hi,
I was just wondering how the OS (in this case, RH ES 3.0) decides which IP address to put into an outgoing packet.
I have an interface with several IP addresses assigned to it, i.e. there I have the following setup:
eth0: - IP address 1 on subnet 1, a /28 subnet eth0:0 - IP address 2 on subnet 1, a /28 subnet eth0:1 - IP address 1 on subnet 2, a /27 subnet eth0:2 - IP address 2 on subnet 2, a /27 subnet
I always thought outgoing packets would have the address of eth0. To my surprise, they have the address of eth0:1.
If anyone has a hint on why this might be so, please do tell.
If you add 'NO_ALIASROUTING=yes' to ifcfg-eth0 that ought to stop it and always make eth0 the source instead of the aliases.
