OT: ? for you computer networking geeks

[moonpod]

I have a Belkin Pre N Router and one of the Panasonic Wireless Webcams. I can get it to work locally no problems. I can't get it to work via the internet. I set the router for UPnP, but whenever I try to get it setup, it tells me that the UPnP isn't working. Any ideas? Do I need to power cycle the router?

I mentioned this issue in the last thread you posted on the topic. I assume you are trying to access the webcam from outside your home (or wherever the router is set up)? I also assume your webcam is connected on a wireless link to the router.

Here are a few things you have to make sure of in order to access the webcam from outside:
1) You must set up Port Forwarding on the router to direct all WWW (HTTP) traffic to the local address of the camera. So, if your camera has address 192.168.0.100, for example, you will have to create a Port Forward on the router for WWW (HTTP) that goes to 192.168.0.100. You should give your router a static address and port forward to that address. If it's dynamic, it could change, and ruin the port forwarding. You must check what ports the webcam actually requires. It may be WWW/HTTP, or it might be another, or it might be many. The manual should tell you.
2) You must ensure you can access your router via the internet. Your internet modem (do you use DSL, cable, fiber, something else?) will have an IP address, or perhaps you have a domain name that already points to it. When you enter that address in a browser, it will try to reach your router. Your ISP might block your modem or router from responding (blocking servers is common practice for home users). If they don't block, then if you have done step 1 correctly, you will actually get the webcam and everything should work.
3) Again, what kind of internet service do you use? Does it provide a static IP address? If not, you will have to contend with a changing IP address to access your router from the internet. There are services to handle this, such as www.dyndns.com
4) If all else fails, you can use the webcam's feature of posting to a server so you do not have to access it directly. This is a very good option, assuming the webcam supports it and does it well.

Is there a port address for your wireless webcam? You might need to forward that port to your cam in your router. Should be under port forwarding. Enter the port number for you web cam then the ip address of the web cam. What this does is when you are on the internet it tells the router which device you are trying to access. Otherwise it doesnt know if you want to access the PC, the router itself or the cam.

Also from the internet you have to type the IP address of your internet IP and not the webcam IP directly. You can go to www.whatsmyip.org to check your internet IP

See that's the thing....the router is supposed to be UPnP compatible, which means there's no obvious way to port forward on the router. Any ideas?

I know about getting the static IP addy.

I have the same PreN router. I dont remember offhand where it is, but you can do port forwarding.

 

[moonpod]

Well if you can remember..HELP, b/c I can't find an obvious way to do it in the router control thing.

Its under the title:
Configuring Internal Forwarding Settings

I think to access your router you have to type 192.168.2.1 on your browser page with no www in front of it

 

[moonpod]

sweet. Thanks.

If I ever get home tonight, I'll try it.

192.163.2.263 is the camera. port 80 for wireless? I think that's what the computer gave me.

Does anyone know? Is SBC DSL dynamic or static?

Chuck,

Most likely dynamic unless its a business account. Static IP cost a little more a month if you want it under a residential account. If you have the dynamic IP it should not change daily unless you turn off the router and DSL modem. If you leave the DSL modem and router on then usually your IP should stay the same for weeks or even months at a time.

 

[moonpod]

coolio. I just gotta get home at some point....

 

[Wilafur]

andele!

 

[Zaphod]

a lot of cable internet providors block port 80. may need to use 8081.

 

[moonpod]

It's DSL...does that matter?

Wilbur, I've still got a whole lot of work.

 

[Wilafur]

ya, you still need to send me an email.

 

[moonpod]

about this weekend? OK. I need to talk to my inlaws.

 

[moonpod]

AAAGGGHHH!!!! Still not working.....

From your work or anywhere outside of you camera network make sure you can at least see if you can communicate with your router. If you are using Windows XP, 2000, etc go to a DOS prompt "Start, run, and type CMD" Then type without the quotes " PING xx.xx.xx.xx " where xx is your IP address ie. PING 12.34.56.78. If you are timing out then you have the wrong IP address. If you get a reply then perhaps you should change the port number on your wireless camera. Perhaps change it from 80 to 8080. Make sure you change the port forwarding on your router to 8080 as well.
To access your camera you open your browser and type you IP address and then the port number "http:\\xx.xx.xx.xx:8080" where the xx is your IP address ie http:\\12.34.56.78:8080. The colon 8080 tells the browser to go to that specific port. Hope this works.

Note: your ip address on the outside does not start with "192.168.xx.xx" That IP address only works from your internal network. You can go to www.whatsmyip.org to check your actual DSL ip (do this from the PC where the CAM is on the router as your PC)

 

[Zaphod]

He most likely can't ping his router most block ping. Most likely it is in his port forwarding and or his camera not having a static IP and it keeps changeing.

 

[moonpod]

The camera IP is the same. My router IP hasn't changed....I assume I'd have to power cycle the router to make the IP change, no?

I dunno, I think I set up the port forwarding correctly, but it won't work. Frustrating. From within the local network, absolutely no problems. Works like a charm.
