I set up our WP site to work locally under Wamp that installs Apache 2.2.21. The network administrator put the server outside the firewall (this is a Windows 2008 R2 server), so that the site can be accessed externally. In doing so, the IP changed, and I modified the WordPress database and various html/php files to reflect the new IP number. Keep in mind that the actual production site is functioning and hosted by a hosting company with the domain name associated with the site. Right now all I want to do is to be able to access the site externally with the IP number.
Also keep in mind that if I type in (example number): http://192.168.9.999/nameofsite into a browser on the server that contains the site, the site runs ok, and I can access the WordPress administration page from that server.
When I type in in http://192.168.9.999/nameofsite into an external browser, it gives, "Web Page Not Available". I check the Apache access log, and there are no entries. I cannot ping the 192.168.9.999 externally.
Keep in mind the site physically resides in d:\wamp\www\nameofsite.
I did go into d:/wamp/bin/apache/apache2.2.21/conf/httpd.conf and change the "ServerName localhost:80" to "ServerName 192.168.9.999:80". I restarted Wamp, but that didn't change anything.
So my question is, are there clear, detailed, specific and explicit instructions for getting your WordPress site to be accessed externally using Apache once it works as a localhost?
