Each jail requires its own IP address. There are things that people do with jails with private IPs and packet forwarding and stuff, but to keep it simple, consider that each jail needs an IP address (public). If you have lots of them, and if each domain is something someone else runs, or is based on totally different SW, then you might consider separating them. If you own and run each domain and they use a similar SW menu, then you may just run them out of one jail using apache virtual hosts. > > q. If I am using a jail for each domain, does this imply loading > apache+php+mysql, for each www jail ? Yes. There are ways to share but until you are comfortable with jails and what you are doing, it is easier to just load each one up separately. We run a ton of jails, one for each customer, and we share SW across them in our own "/usr/public" read only area with each jail having its own /usr/local/etc but to get it to work requires some configuration work and understanding how it all works and some other trickery... > > q.

You could but in most cases there is no reason to do that. Run them all in 1 jail using one set of SW. Set up your SMTP server to support multiple domains (I recommend exim). > > q.
