I'm trying to set up 2 IP aliases on my firewall box. It's Redhat 7.2. I believe I have the 2 alias (eth0:0 and eth0:1) set up properly. Is there anything in particular I need to do with iptables to activate these 2 interfaces? I've attempted to execute rules with the interface specified as eth0:0 and iptables does not seem to like that. Anyone have any docs I can read about proper IP aliasing under Redhat and what I need to do for iptables?
Thanks!
