Is there UPNP option to enabel it in paradyne routers? i cant find any related options when configuring the router

Since you aren't specific about the model of Belkin router you are using, I can only give you some general advice. This is what is have from MY Belkin router manual. Yours may be different....

Enabling/Disabling UPnP
UPnP (Universal Plug-and-Play) is yet another advanced feature offered by your Belkin Router. It is a technology that offers seamless operation of voice messaging, video messaging, games, and other applications that are UPnP-compliant. Some applications require the Router's firewall to be configured in a specific way to operate properly. This usually requires opening TCP and UDP ports. An application that is UPnP-compliant has the ability to communicate with the Router, basically "telling" the Router which way it needs the firewall configured. The Router ships with the UPnP feature disabled. If you are using any applications that are UPnP-compliant, and wish to take advantage of the UPnP features, you can enable the UPnP feature. Simply select "Enable" in the "UPnP Enabling" section of the "System Settings" page. Click "Apply Changes" to save the change.

does vizio support upnp?

You need to access your router and set uPnP to enabled.
to do this you have yo use your browser to access the router - the address for the router will be an Internet Protocol (IP) address.
Log into the router and select uPnP (usually on the security or advanced option)
if you let me know the make and model of your router I can give you more specific instructions.
If your router does not have a uPnP option (and this is very unlikely) again let me know and I can give you detail on port forwarding and how to do it.

yes,you will have to use the port trigger option in under the "configuration tab" and check "UDP"

To access your camera from the Internet you will need to configure uPnP (or configure port forwarding manually) and register with some kind of dns service like viewnetcam (or know your home's external IP address assigned by your Internet Service Provider).

1. To configure uPnP on your camera, look in the network settings for an automatic network configuration option - this will trigger the camera to talk to your router using uPnP to set up port forwarding. The default for one camera is to use port 80 for the outside port and something like 192.168.1.253 for the internal network address (internal to your home only). uPnP will try to configure the second and third cameras to external ports 50000 or 50001. My router failed to configure the 3rd camera so I had to manually add a port forwarding option from my router's admin pages. To note, you can configure all port forwarding manually from within the router admin pages. Just list the internal network address to your camera (like 192.168.2.253) and specify a different port for each camera (like 50000 to 50000). You can then access your camera by typing in 192.168.2.253:5000

2. Then, you should register with viewnetcam.com. Adding your cameras on viewnetcam will give you access to them from outside your house without you having to know the IP address to your home network. You will simply type in your viewnetcam url with ":" and the port number (like username.viewnetcam.com:50000).

Note: When trying to access your camera from outside your home (or even pinging your router from outside your home), you need to know the IP address of your home. This is assigned by your Internet Service Provided and can change every time you reboot your modem. Services like viewnetcam keep track of the IP address to your home and update it automatically when it changes (your camera will communicate with Viewnetcam servers occasionally to update the IP address). All you have to remember is one constant URL (the viewnetcam url) and you can get to your cameras!

The netgear prosafe VPN router is a high-end component ment for business and corporate use and does not support UPnP

UPnP (Universal Plug and Play) allows programs accessing your router (limewire, utorrent, etc...) to auto configure the security settings on your router which would be harmful to a business/corp. network.

Under applications and gaming, you will want to select upnp forwarding and then you can enter whatever custom application you want to be allowed in or out.Upnp can also be set automatically from the Administration menu.
You will need to know which ports to use, usually you can get these from the software developer, such as bungie. You can also use the application name, but I find the numbers easier to work with.

Go under LAN setup and enable NAT and Firewall services. Then go to LAN configuration to enable the dhcp server. Set the Start IP range and ending address.

Go to options>preferences>connection
You can set the port there and also Upnp mapping so that if your router is upnp ready it will be automatic

This is your router trying to connect to the modem, ensure that the routers wireless connection is enabled and see if your router when you access it is giving your pc an ip address. Make sure DHCP is enabled for automatic ip address allocation. Run this programme, click Start>run then type ipconfig /flushdns then press enter. This will flush any old addresses given by the modem.
