What does netstat tell you about port 80? I.e. what does
netstat -an | grep ":80"
return?

It is possible that your web server is configured to only listen to
port 80 on the local network.  If you are running apache this is
configured with the listen directive in httpd.conf
http://httpd.apache.org/docs/mod/core.html#listen
yours may be something like
Listen 192.168.0.1:80
where you probably want it to be just
Listen 80
