I have a set of 5 IP cameras running on a server at my shop, I am using the AXXON software to run it. When I install the Axxon Client software on my laptop on connect wirelessly while in the shop, it automatically sees the server and connects.
However, when I bring my laptop home it does not connect (obviously). Instead of the servers name (which is what it looks at while on the network) I can input an IP address instead.
So I input the IP of the WAN the server is on (found via IPChicken.com) and try to connect... it does not.
The router the server is connected to is a Trendnet TEW-652BRP if that makes a difference.
Your setup might be different from mine but I have to go all the way to the internal IP, separating the external IP from the internal one I fixed for my camera. The more cameras you have, the more internal IPs you need to allocate. The URL syntax is then similar to- 176.255.***.**,192.168.1.16.
