You need to place zone data for domain2.nu in the zone file for
domain2.nu, not in the one for domain1.nu.

You should probably have only one PTR record for each IP address.

When doing name-based virtual web hosting, all DNS needs to do is point
host names to the correct IP addresses, e.g. "www.domain2.nu. A 10.0.0.1"
or "www.domain2.nu. CNAME server-01.domain.nu." - If this works, I'd look
at the Apache httpd.conf instead. If the main site comes up instead of the
desired virtual site, there's probably something wrong with the Host
headers; either the user agent isn't sending them, or the server doesn't
process them as you intended. This is easy to troubleshoot by telnetting
to port 80 and issuing raw HTTP requests, e.g.:

HEAD / HTTP/1.1
Host: www.domain2.nu

(followed by two carriage returns)

Setting up name-based virtual hosting is usually quite uncomplicated using
the RTFM method, but if this fails, a suitable place for follow-ups would
probably be comp.infosystems.www.servers.misc. Good luck!
