Hi

I have two different IP addresses (in a block of /29), one is on port 0 and the other is on port 2 of a Ciso 888. I am doing this so I can have two different certs with two different ip addresses.

I have tried:

1. one machine, two real interfaces, two cables (eth0 and eth2)
2. one machine, one real interface eth0 and one virtual interface eth0:1, one network cable

Using number 2) I can ping the two different ip addresses, no problem. The only problem here is that iptables does not work (I cannot create rules for eth0:1 - and yes I know about the security implications).

Why do you need different rules for eth0:1? Can't you specify the IP addresses?
