ASUSCOMM.COM DDNS Drops responding 4/16/26

[Radon]

Just an FYI, my AsusMerlin Wireguard would not connect yesterday and I noticed that my DDNS had lost contact to server. At the time there was no outage reported. I ended up making an account with No-Ip and setup a key and A record. Let's encrypt dropped my cert in seconds after entering the data. Just uninstalled and reinstalled Wireguard to pickup the new DDNS. Should have posted yesterday however I didn't confirm the outage until I pulled half my hair out.

Known issue. Asus DDNS has been unreliable for years.

Hi, can you kindly post your DDNS screenshot with NO-IP? Thanks.

The instructions show old firmware, but no much changes in DDNS setup:

No-IP Free, must update once a month via email, I have a category filter in outlook that codes the email from no-ip in RED.

Yeah I noticed that too, fortunately my trusty @Tailmon install was immediately available to cover the down time.

TBH, I don’t find it happens very often, once every 6 months maybe. I use VPN a lot so it’s not like I don’t notice it through lack of use.

@jksmurf Mine had been running solid for 5 years w/asuscomm. I'll have to check into the Tailmon. Haven't used that yet, thanks for the pro tip!

I can’t see a signature so I’m not sure what HW or FW you’re running, but just a heads up, it runs on Merlin FW only.

Tailmon is a really neat Addon which sets and manages a Tailscale install, but doesn’t need a DDNS to operate.

TAILMON v1.3.2 Released April 16, 2026 First off – Wanted to give huge thanks to @jksmurf for lighting this fire… He opened my eyes to Tailscale and its capabilities, and only became natural to want to fullfill his wishes to create a formal installer/monitor for this valuable tool for others to...

You helped me a couple weeks ago with the next to last version of AMTM concerning the auto updates. Back when I was buying this for business from Sophos, I'd drop a grand a year for application blocking and firewall updates. Been running this at home for a long time works excellent!

Well then, good to go. Add Tailmon, set it up.

Maybe also a good time to add a signature to your forum profile with Router HW and FW.

How often your leased IP changes? On my ISPs to the same MAC device it's... never.

 

[Radon]

My fiber provider doesn't change the IP very often, usually only when I call because someone with a backhoe gets a little wild and they think rebooting my gateway will help . When asuscomm went down the IP hadn't changed however the DDNS was coded into my VPN and couldn't find its way home.

The No-IP paid service is well worth the few bucks a year that it costs. My ISP can change the router IP address every reboot and it can change, usually dosen't, several times a day as the DNS Lease time is 30 minutes.
