Getting DDSN to work on my R6400 router
R6400/Firmware Version V22.214.171.124_1.0.28
I have a rather complicated network topology: I get my internet connection via an ISP provided ADSL router, my firewall box (SonicWall) and wired network host is connected to the ADSL router via its DMZ address (192.168.1.30) thus all traffic is routed to the SonicWall. Then the R6400 router is connected to the SonicWall wired network, for example 192.168.55.12. The R6400 network is 192.168.57.1.
OK? Well today I decided to try using the Netgear Dynamic DNS function. It set up easily and I was happy. A couple hours later my ISP change my IP addess, this happens about once a week or when there is a network outage. I immediately noticed that the new DDNS address (xxxx.mynetgear.com) did not change!
Rebooting my router did force an update, but this is not the way I want it to work. Why did the R6400 router not update the DDSN server? I suspect (and please tell me I'm wrong) it is related to the fact that, in fact, the R6400 router's ip address had not changed, it was still 192.168.55.12.
Assuming my analysis is correct, is there a way to periodically for an update to the DDNS server?
