I've got 3 different sets of public ips, each with it's own static ips, and default gateways, and only one physical ethernet port.

I'd like to be able to setup domUs that use the various ips, and route through the gateway for that particular IP. My problem is that when I setup these ip addresses as alias on eth:0, only one set of ips/netmask/gateway will work.

any suggestions on how to set this up?
I'm using centos 5.4, xen3. I've tried setting this up using ip aliasing (eth0:1, eth0:2, eth0:3), but that doesn't work. (Xen seems to reconfigure the network, breaking the alias)

thanks, any suggestions would be greatly appreciated!
