Dynamic IP and IP camera issues.

[HarryM1BYT]

My ISP provides me with a dynamic IP, in other words it can change every time I disconnect and reconnect my broadband to the WAN.

I have an IP camera which has an internal to my LAN IP.

I recently had some issues with my original broadband router so I swapped it out for another, but when installed, I could access the cam either via my LAN - or when away, via the Internet (WAN).

I think I may have set up my inbound ports correctly to allow access to the cam from the WAN on the replacement router, but it still doesn't work when accessed from the WAN.

Now this is the bit where I am getting out of my depth....
Because I am on a dynamic IP, I access the camera via a dynamic IP server provided by the camera's manufacturer. If I log into the server, to check on what it thinks my IP is, it reports my WAN IP completely wrongly and not updated for a few months. That is the problem I need to resolve first, but I don't understand how a Dynamic IP server works, how it gets my current WAN IP?

My guess would be that my router has to regularly report my IP back to the server, but it is not doing that, so how do I set it up...

My router has a Dynamic DNS settings page, but it only seems to allow the choice of - Service Provider www.dynDNS.ORG - am I looking at completely the wrong thing here?
