I have an ip camera set up on my wireless LAN.
IP 192.168.1.19:89
1.  I did set up a free DDNS:
    Hostname             laundrycamera.dlinkddns.com 
    IP in DNS              192.168.1.19
    Browser IP address 27.96.214.117 (this is my computer's ip address externally, it is not static)
2. Went to my router's page (i have firmware version AU_2.01) and to Dynamic DNS inside Advanced tab:
   Hostname                           Username   Service   Interface    
   laundrycamera.dlinkddns.com   illumity   dlinkddns   ppp0   
3. Navigated to Port Forwarding on the Advanced tab also
   once set up, it looks something like this:
   Server Name    External Port Protocol Internal Port   Server IP        Use Interface   Lan         Schedule 
                         START   END              START  END                                           Loopback  Rule   
   LaundryCamera   1    100        TCP         1    89       192.168.1.19  ppp0              DISABLED  ALWAYS  
   the interface of firmware verison AU_2.01 looks different to those on the internet and i cannot be sure i    have put the correct details in the correct place.
4. I go to http://laundrycamera.dlinkddns.com/ and the web page is not available. Please help me!!
NOTE: I can view the camera over wireless LAN at http://192.168.1.19:89/index1.htm
I have also tried changing start end port to 89 for both internal and external on the point 3 above.
