that's just like a secondary address on any other device.

When people run out of addresses, instead of readdressing evrything with a new bigger subnet, you can just add a new subnet and use secondary addresses.

Yes. The CSS will automatically route traffic between all interfaces unless you specifically deny it.

Thanks,

One more thing, do you know if the css makes routing between these two IP networks?
