I have WAMP on Windows XP, and the Apache server runs just fine if I access the content via localhost.
I followed this guide to set up access from other clients: http://www.petri.co.il/install_wamp_server_on_vista.htm
So, I opened port 80 in my router to forward requests to Apache. Went to www.whatismyip.com to see where to point my browser. The server is actually hit, but takes forever to load content and the browser eventually gives up. Any ideas?
