Camera access, Wan works, Lan doesnt

[kater1]

Hey all,

I setup a new camera last night. I am able to access it thru the Wan using dyndns when I am on 4g. When I switch to my home WiFi I am not able to access it using Dyndns. If I use the 192.168.x.x address I can access it thru my home wifi..

I have other cameras setup that work fine. It is a different brand camera but I am sure I have all settings correct. What am I missing.

I dont know why but I found my problem. Using UPNP to do port forwarding didnt allow WAN access. I manually setup port forwarding and everything works. I dont understand why.

Netgear WNDR3700v4

Manually forwarding ports for permanent connections (like cameras) is always the better option. UPNP is designed for programs that need to temporarily allow an incoming connection (like games).

Yes. But I just can't figure out why it didn't work with UPNP. Maybe a limitation of the router. But as long as it work now I'm good with it.

uPnP can be a security problem.

It is a solution for users that can not (or would Not) like to to understand Port forwarding.

If you do know how to deal with Port forwarding you are better of doing it and Disable UPnP.

In addition when ever I install a camera I always change it active port to some thing else.

The default ports of cameras are common knowledge and using them makes it very easy to scan from the outside and "bridge" the cameras security.

I setup all my cameras under different ports. As most of them have port 80 for http. When you have 6 or 7 up can't use port 80 on all of them so I just change them all. I have a range of up addresses just for cameras and use ports that mimic the ip address of each camera. Makes it easier to remember port numbers. Like 192.186.1.250 would be port 2250. 192.168.1.251 would be port 2251 and so on.
