    Help! I'm about 8 hours into this and still can't quite get it. My network has a westel dsl modem, the WRT54G router and 3 computers; 1 hardwired and 2 wireless. everything has worked great for more than a year. I am trying to set up a samsung home security observation system (ie cameras) for remote viewing. The monitor has a built in web transmitter which I connected via ethernet cable to the router. I configured the setup on the samsung monitor for pppoe and http port 80. dns1 defaults to and dns2 defaults to These are the only variables for pppoe on the samsung setup. if i go to static or dhcp there are others. I also input my dsl username and password. this is where i get really confused. i have set up a static ip on pc network settings (xp) and port forwarding on the router (http/10000to65535/tcp and also tried 80 to 80) but the samsung system still does not "connect" to the router. this is indicated by a flashing "p" in the corner of the screen. i have tried many other things i won"t detail here, firewall settings etc. can someone tell me if my general approach is correct, and if so what am i doing wrong?

    The cameras should be connecting to the router using standard Ethernet, not PPPoE.

    If you are trying to get to the cameras from the Internet, you have to set them up to connect to the router on a specific port (80 is not recommended, try something in the 10000-64000 range).

    From your local network, you should then be able to access the camera on the specified port ( using http://(camera-ip):(port#) )

    Then simply go on the router and forward that port to the camera's IP address (it's better if you get a firmware for your WRT54G that supports Static DHCP so you can have the same IP address for your camera all the time). From there, you access the camera from the Internet by using http://(your_public_ip):(port#)

    Multiple cameras? Use multiple ports.

    Just to be a little more clear on what you are trying to do.

    You DO NOT want your cameras themselves to attempt to log into your Internet connection. Your cameras should be sitting on your router, and your router should be forwarding all requests to the cameras based on the port provided.

    So the camera(s) should connect to the (standard Ethernet) LAN on your WRT54G. By forwarding ports on the router, you allow clients from the Internet to find the camera(s) and look at it(them). By specifying unique ports for each camera, you allow the router to forward the requests to the appropriate camera (local IP address).

    Hope this helps clarify things.

    Thanks for the quick reply. I'm still digesting your comments. more info/questions:
    "The cameras should be connecting to the router using standard Ethernet, not PPPoE"
    My choices are static, DHCP and PPPoE on the samsung config menu. By "Standard Ethernet" you mean static?
    Also, for remote viewing samsung instructs going to http://sff0000.websamsung.net where ff0000 is the MAC address of my samsung web transmitter. My router firmware section Network Address Server Settings (DHCP) includes options for setting static DNS1/2/3 addresses. Is this the same as Static DHCP? There are 4 cameras on the system but they feed into the monitor/web transmitter which processes them into a quad screen display. There is only one output (ethernet) from the monitor to the router.

    :cheer: Update: I am now able to see the cameras on my PC/network. Still working on remote viewing. So far, the samsung link doesn't work. May have something to do with an expired activeX certificate. Thanks NateHoy for directing me away from PPPoE. That seemed to clear some things up.
