The default Apache webpage should load. I am using a raspberry pi as webserver, not my Linksys acm3200 router. port 80 forwarding is enabled. If type in my 4 octect IP, the page comes up. If I use the ddns, it says Bad Request.
If the Apache server is receiving the request, both when using the name or the IP address, but it returns an error when using the name, then the issue is in the Apache server; has it been configured to serve that domain?
