If they're on the same collision domain, then you're not giving 100Mbps
to each service, that would be good. That's why it usually doesn't make
sense (I understand that this is a temporary configuration...).

You can have two IP addresses on the same NIC anyway...

Not so nasty, since there's really no point in having more than one NIC
on the same segment. And the log message is justifiable.

Sorry for my intrusion.
