I have one connection from a cable modem which allocates me an ip address which expires fairly often and spits me a new ip address. This is ok as i have ddns for my connection.

I need to run the full service domains for three seperate groups, a buisness, a non-profit orginization, and my own personal domain and hope to do so off one box running slackware 9.1 as my router/firewall. I have several other boxes which may help, but i would like to have most of the work done on that box. None of these domains will have a very large amount of traffic. I will use virtual hosts, (excuse me if my terminology isnt correct) all of which will need to down diffrent ip addresses from my isp, and have the ddns done for them. eth0, eth0:1 eth0:2, then i conect to my network on eth1 and planned to have a dmz on eth2.

does anyone have any experiance with this? What would be my best plan of action? I have considered user-mode linux for each connection, as well as chrooted plans. I need full service domains, apache, ssh, smtp, pop3, ftp ...etc , for all of these.

any help or ideas would be greatly appreciated.

I would not recommend you do this. You can do it, but you won't have any redundancy.



You don't need to have all of them pointing at a sep IP for virtual hosting through apache, but you can.
See http://httpd.apache.org/docs/vhosts/



I use postfix, here is an explanation for what yoru trying to do.

It really all depends on what packages your going to use to provide these services. You mentioned having several boxes, I would probably configure it so the web and mail servers were completely seperate.



Hope some of this helps.
