Re: Using an device alias?

[Raymond Leach <raymondl@xxxxxxxxxxxxxxxxxxxxxx>]

Hi

It doesn't make sense to attach rules to alias interfaces, since the
packets are coming in the same physical interface whether it is eth0:1
or eth0.

So if you use just eth0 your rules should work as expected as long as
you qualify them further with the correct (alias)ip.
