Help with openvpn server and asus ddns

[ryancharles]

I have an n56u with a qnap TS-121p NAS. I setup openvpn on the NAS, inserted my public ip (174.x.x.x) in my config file, added my port forward rule to my NAS and voila, everything is working.

then I wanted to enable and setup ddns for when my public ip changes. I decided to use the asus DDNS service. Logged into the router, navigated to the DDNS tab, registered my name and I got the message that mydomain.asuscomm.com should now resolve to my public router ip.

I noticed that on the front page there's a yellow outlined exclamation mark next to my DDNS name mydomain.asuscomm.com. When I used nslookup to lookup mydomain.asuscomm.com it does not resolve to 174.*.*.*. It resolved to 217.162.*.* I Replaced the public ip with mydomain.asuscomm.com in my openvpn config file and due to the incorrect resolution my vpn is no longer connecting.

Am I missing something? Any help would be appreciated.

Did you try a reboot of the router?

Just tried a reboot. Still a yellow exclamation mark and still not resolving correctly via nslookup.

Check the System Log, and see if there's a more specific error in there regarding ez-ipupdate.

Have you tried changing your domain name to something else? I had this happened to me when I switched routers, from N66u to AC66u and tried using the same ddns domain name with asus ddns service, had to registered another name in order for it to work - now I can access my network from outside (external IP)
