Look at the httpd logs to see where the page went. On
my RH 5.2 web server, whenever I connect from a LAN
machine, the logs show the LAN IP, even though I use
the FQDN.
Also, /etc/hosts.allow and /etc/hosts.deny have nothing
to do with your web server. httpd is a daemon that
monitors port 80, and inetd monitors the ports in
/etc/inetd.conf. You could stop inetd completely, and
your web server will still work.
