I am trying to get my IP camera to work - Belkin (F5D72304F5D7000) Router

you can try this http://www.whoisxy.com/ ,here i got the details about the dns query ,ip to domain ,domain to ip etc........you can get more about the ipadress......

try this one? 192.168.0.253
look at link below.. http://www.networkwebcams.co.uk/blog/2007/10/22/howto-set-up-your-panasonic-camera-to-work-on-your-wireless-network/

first you try to ping the ip address of the camera.if you getting the replay that means it is working if it not then you have to chek ur lan setting.

What are you using to view the Camera? Is this the only IP camera you are viewing/.accessing on the network? If it is not, are you using different IPs in the non-DHCP pool.
Typically you do not have to set-up port forwarding to gain access to the camera within the network. Normally port forwarding is set-up when you are outside your network and need to gain access to different applications/devices in your network using the same static IP address.
Let say you have a camera ip on 192.168.1.20.
You can connect to the camera with your web browser inside your network with the IP 192.168.1.20 (obviously), but if you have the camera set up to only be triggered on a specific port (other than the browser's default 80) let's say 100, then you would enter 192.168.1.20:100.
If the only thing on your network is the camera that you want to access from outside. you would setup in your router to route all incoming requests from port 80 (which is the web browser default) to the IP of the camera. Sometimes routers ask for a range just enter 80 to 80.
If the camera is working on a different port like 8001 then you would port forward 8001 to 8001 to IP 192.168.1.20. You would enter in your web browser (off-site) your static IP 69.132.54.176:8001. But I would suggest if the camera is the only thing you will be trying to gain remote access to, then leave it at 80 and set up forwarding for port 80 to the IP.
That way you can set up a free DNS service and not worry about paying extra for a static.

let me give you few suggestions and then you can take it from there.

firstly IP camera is just what its name says..it needs a fixed IP address it may be local as in your lan where it is working or a IP address from ISP.
Now when you connect it behind router... it is essentially a camera connected to LAN.
now the problem is DYNDNS.com will give access to your router since that is connected to dynamic IP addressing. However Ip camera is behind router and to access it you need to open proper protocol and port in router .consult your router manual for doing that.

with your current setup that is the only solution. however you can connect Ip camera directly to ISP line and then use dyndns as in case of router. though i dont know how feasible that will be for you.you have not mentioned IP camera model so cant help with specific details.

check the firewall, see if is not blocking your webcam
if you have a router, enable port forwarding for webcam

usually webcam uses TCP port 5100 for yahoo messenger

you have to log into the main IP address, not the camera IP address. If you are using wireless, the camera will have an IP address different than the one for the router coming from the ISP.
I just bought this camera myself and am trying to work out the kinks. My ip keeps changing and i am not sure how to keep it the same, static?

Can you view the stream in IE or IP surveillence or is it that you hit the camera in IE, the sign in box shows up (cause you put in a pasword), you put in the password, and it cannot connect and says retry.

Possible problems.....

The IP you are typing in is really not the IP of the camera (comes from the box being checked that says 'reset the IP on reboot') Use the installation Wizard to find the camera and it's IP.
Your firewall is blocking the stream. Try disabling it and reconnecting.
Your cameras IP is not in the range of the DHCP server of the router it's connected to. Review your router's DHCP list to see if the camera IP is in that range.
The password on the camera is corrupt. You will need to hard reset the camera and reset it back up from scratch to connect.

Worst comes to worse, you can always just hard reset the camera and start over.

make sure you are using a crossover cable. A straight through ethernet cable will not work for talking with your computer. Next, go to your network connections. click on TCP/IP properties and enter in for the IP address 192.168.0.101 and a subnet mask of 255.255.255.0 apply it. go back to network connections and disable then enable your connection. Now go to the Sony IP setup program. Double click on your camera when it appears. Don't forget the default address of the camera is 192.168.0.100.

I think maybe the problem is that the cam has already been recognised and given an ip address when you connect via RJ45 cable, but when you try wirelessly, there is a replication of the ip address which is not allowed. Check your router to see what ip address was given to the cam and remove if neccasary so as to re new the cam ipaddress. I would turn off the encryption first to try and get it working, then turn on again.
