I have list of public ip addresses used for hosting different websites (intel machine). I also have an AIX 5.1 machine used as Firewall. The AIX has 3 NIC, 1 used for Public, 2nd NIC used for secured LAN, 3rd NIC used for DMZ. Currrently, the 3rd NIC only used for my Mail server.
Can i used the 3rd NIC to host mulitple webservers using only one NIC? How can i configure the 3rd NIC so that all my websites & mail server can be seen? is "IP Alias" the right answer to it? If so, please help me how can i configure one NIC to have mulitple ip addresses?
