Idea - Anyway to run the No-ip DUC on the router?

[Eric Lieb]

I use no-ip for dynamic dns http://www.noip.com/download?page=linux - anyway to integrate this into the router so the router updates the dynamic dns with the ip address instead of relying on a computer to do it?

DDNS tab in WAN section. Might depend on firmware version, but no ip is there on mine.

I have no-up DDNS setup and working on my 88U no issues. As suggested in the quote above, there is a specific DDNS tab for it, or at least there is in my 88U running Merlin 380.65.0.

No-ip is supported inside the firmware

Wan > DDNS

suggest you take some time and check out the firmware and its features cause there is no need for no-ip software an if you need additonal ddns providers i suggest you check out the wiki

I'll add to this a feature I'd love to see: DDNS updates for each VPN client. I run an OpenVPN client with a couple devices routed through it via policy rules. It would be great if DDNS could also update for those clients through the VPN tunnel. Right now I have the NoIP DUC running on one of the computers. It works fine, but it would be great to offload those functions to the router so I'm not dependent on that specific computer to be up and running to keep NoIP up to date.

You will need a custom DDNS update script that is called by openvpn-event.

Simply tell curl to use the VPN tunnel:

e.g. retrieve your VPN end-point external I/P

curl --interface tun11 http://ipecho.net/plain;echo

and update your DDNS via the VPN:

curl --interface tun11 http://username:password@dynupdate.no-ip.com/nic/update?hostname=mytest.testdomain.com&myip=1.2.3.4

a little scripting is all it takes

Fantastic! I'll give this a try later this weekend. I love how helpful and resourceful members of this forum are!

Awesome the DDNS works just fine.. Didn't know it was there (had searched previously but couldn't find it). Question... How often does it update the ip to no-ip? The DUC client does it like every 5 minutes or something. I am guessing this is what the "Forced refresh interval (in days) is.. Is it possible to use fractional days in this setting? Would suck to have an IP change by my ISP and have to wait 24 hours for the router to refresh it.

Edit: Removed my previous question... Turns out when DDNS is enabled it automatically will enter the DDNS into the opvn file... WOOT!

Bump

 

[JemTheWire]

Why the Bump?

 

[swetoast]

why bump its in the firmware no need for a DUC

 

[JemTheWire]

Weird. He admits himself in post #9 that DDNS works just fine...

Posted that in my last reply before the bump.

Forced refresh every day, but notice the other setting? 'Check Every....' I have mine to 30 minutes.

Ahh I didnt have WAN IP and hostname verification set to yes.

I set it to every 30 minutes but I just checked in No-ip and it shows "Last Updated" 22 hours ago... Does it just check and only update if there is a change with this setting? The DUC software would actually update it (and it would display as last updated) every x minutes.

@RMerlin mind helping this confused user ?
