I have a domain name registered with a company called no-ip. Their a company providing me direct connection to the Internet where I can use my own server. Seperately I have a ISP. The problem is my ISP is blocking port 80. The good thing is my no-ip service allows me to set a Port Redirect to port 8080, but the bad thing is they can only send the IP address instead of the doman name. So know when I have some of my friends connect to test my site the IP address shows in the Address Bar. So, before going live I want to correct this using the RewriteRule on the server side not the directory. I have Drupal setup using multiple sites. How can change the incoming IP Address during connection to the domain name so it will appear in the users browser normally using the RewriteRule? Can you show me examples how to do this? I'm studying the documents on Apache.org, but this will take time. I normally do all my development .NET Framework. Thanks for your help!...
