Asus DDNS Problem connecting

[psychbiz]

Can someone tell me what this symbol might mean (circled in red) ? I'm having trouble connecting to VPN server after exporting client configuration using Asus DDNS.

This means ddns is not updating or cannot connect to host provider.

Ah! That certainly confirms my problem then. Many thanks.

I didn't do anything special when I bought this RT-AC86U. Just flashed it with latest Merlin firmware, set up VPN (which has never connected) and configured Asus DDNS with same settings as my previous RT-AC66U, which worked fine. What sort of reasons might there be for Asus DDNS connection failing? How could I begin to troubleshoot this issue?

your asusddns is binded to the device!

first release it on the old router to reuse same name!
change it to some stupid long and phantastic name or wait 3-6 months for auto-release.

@RMerlin has made ample changes to the DDNS system you may want to update to 384.7 beta2 to see the changes and find out if it helps any. There are a lot of reasons that can fail. I used to have an issue with the dns I was using. I stopped using DDNS and now have a static ip.

If I'm correct, your Asus DDNS hostname is linked to your device. If you carried it over to your new router, that just might be the issue. Did you get any error messages when entering the details on the DDNS page and applying them?

It seems just registering a different hostname for asuscomm.com solved the problem completely. I thought I would be able to use the same DDNS hostname on my new router as the old one. Apparently not.....

To test I tried to reconfigure the original hostname from my old router and it said it was already in use. No problems with the new one though.
There wasn't any error message when I first set up DDNS on this new router. Just the yellow symbol which I didn't know the significance of.

Many thanks for to all for your explanations. Very much appreciated.

Reviving an old post here

I am experiencing similar problems. I originally thought I had to us a product like No-IP to allow a DDNS connection to my router - so I set one up. Once I was completed the hostname took me to the ISP Modem, not to the router where I wanted to go.

As I dove further into this I found that ASUS has its own DDNS system and I ould use their product .asuscomm.com however once I set it up there - I had the yellow exclamation point described above. Along with a message invalid IP address.

Note: I am using a SmartDNS to work around geo-blocking out of the US. Not sure if this is a factor.

Lastly - I tried switching back to the No-IP DDNS and it no longer works either 404 Not Found Error.

ASUS has opened a support ticket for me, but at this point they haven't been able to resolve the issue.

Any ideas what I can do?

Does it say invalid IP address or perhaps invalid DDNS address?

Invalid IP Address

The WAN address of your router is being seen as a private address ie an address reserved for private networks and not a public address.

Is this router behind another router?

What’s the WAN IP address shown on your home page?

 

[dkalbach]

Its behind the ISP's modem / router - but have the radio functions turned off - LAN from Modem to Router

WAN IP on home page is the 192.168.1.2 - the router (ASUS) itself is 192.168.2.1

 

[martinr]

That’s the problem: your Asus router is on the private LAN of your ISP router.

This topic has been before on the forum. I ran a Google search and picked one that might offer some ideas:

Is there a valid reason why you have 2 router’s cascaded?

Could you, for example, put your ISP modem-router into bridge mode so it acts only as a modem and make your Asus router the only router,

Sorry - I hadn't realized I was in the Merlin section again - started from a search which sounded like a similar issue.

Unfortunately the modem firmware is pretty basic. I don't believe it will accept a bridge mode. I'll contact the ISP on Monday to see about an upgraded modem. Currently in the Philippines, so for the most part if it's not plug and play they aren't very helpful.

As for the local IP address. If I can bridge the modem, should I be able to set up a DDNS on the router even though running SmartDNSProxy?

I imagine there wouldn’t be a problem, because all your DDNS service is doing is making sure that the world knows that regardless of your public IP address or how often it changes, it will always lead to your router within seconds of a different IP address being assigned. Just as if you had a fixed IP address.
