Here's a way to do it without patches:
1. in your webserver:
a. ipfw add fwd localhost from any to 1.2.3/24 http
b. add <VirtualHost...> sections, like this:
<VirtualHost 1.2.3.4>
ServerName web.freebsd.org
ServerAdmin [EMAIL PROTECTED]
DocumentRoot /home/web
</VirtualHost>
2. in your router: add a route to forward 1.2.3/24 to your webserver
Pros:
- no need to 'ifconfig xyz alias...'.
- address matching is fast, since only a few ipfw rules are checked,
rather than lists of hundreds or thousands of IP addresses
Cons:
- I don't think arp will work on 1.2.3/24 addresses, which is why the
route needs to be added to the router.
Try it: it really works, thanks to Julian Elischer.
