If you only have two IP addresses you don't need to use the -rangeX
method. Sorry about suggesting that. I would just alias eth0 to eth0:0
and use it. The way to accomplish this is by copying ifcfg-eth0 to
ifcfg-eth0:0.
The host can really only have one active default gateway. You can add
multiples, but it will only use one of them based on the gw metric
setting. However, are you sure that you need a second gateway or
special routing?
>From your configs below it doesn't look like you even need a second IP
address. A host on one subnet should be able to access the server on a
second subnet assuming that there is a correct route on the switch(es)
that everyone is connecting to.
Alternatively, if still needed, you can add static routes on the server
in /etc/sysconfig/static-routes.
I'm still at a bit of a loss on your architecture, what is upstream from
that server, why are their two subnets, and do the two subnets already
have a route between them?
