Re: Hardware Requirements for Multiple IPs

So you mean create an ifcfg-eth0:1 file, create it with the new IP, add the new IP to /etc/hosts, then run ./ifup eth0:1

or

ifcfg-eth1:1 as the case may be...

Am I on the right track here?

Is there any performance advantage to adding a 3rd network card?

Thanks

Bob

I was recently issued a second IP address of bbb.bbb.bbb.bbb through my ISP. This is over DSL. I just want to clarify an issue with delivery of data on this IP address. I will get data for this IP through the same phone line and the same DSL modem that I presently have, is this right right?

I currently have a Red Hat 9-based firewall computer which successfully routes data between my first IP address (aaa.aaa.aaa.aaa) and the internal home network. It is an old computer that has 2 ethernet cards installed on it. Do I need to change my kernel routing table on that machine to accomodate the new IP, or do I need a 3rd ethernet card in addition to routing table changes and firewall script changes?

Thanks for your advice. I do not often do this sort of thing so I'm inexperienced.


You don't actually need any additional hardware. Just use the "ip" command to use the additional IP on the same ethernet interface.
