hello guys, I'm experiencing a strange problem with iptables nat configuration. I've set up a star firewall with 3 physical NIC. I've configured two oh them with multi-ip assignement. let's go to the core of the problem. it seems that the iface identified by eth0_1, eth0_0 are not recognized by iptables. if I change the name using the less qualified eth0 (adding some more details to discriminate the source) it works. where I am wrong? I have also noticed that iptable accept any name to identify the NIC. my workaround is not so elegant. there's another way to name the iface multiIPed? thanx in advance *g Giovanni Costagliola [IT Senior Consultant]
