Neither INADYN nor DD-WRT uses checkip.amazonaws.com for external IP checking that I'm aware of.

code starts there

but thats C code, you cant run that in commands tab, well you can, if you want to kill kittens, drown babies and set houses on fire. We always need more people on the Arkham asylum.

That takes time and BS is possibly very busy fixing all other things. Smile

Could DD-WRT use a shorter "Force Update Internal"? Currently, its unit is "Days", not "Hours".

Also, you cannot specify what ifconfig interface to monitor for IP change. Um... maybe I should start a new thread....

Can anyone share the "check external IP" script/code and I can tinker with that and see if there's some way to break through CG-NAT and get a real external IP returned to me?

I could tinker and just run changes via "admin/commands" and report back.

Is your T-mobile using PPPOE protocol to get WAN IP? Or is it DHCP?

#1207 (DDNS / INADYN - Add option to "Use WAN IP Address") – DD-WRT
https://svn.dd-wrt.com/ticket/1207

* Add option to "Use WAN IP Address"

Might be you need an ability to track the interface instead? For example if you want to use PPPoE over WAN then you need track changes on ppp0 interface.


DD-WRT :: View topic - DDNS, INADYN discover wrong WAN IP
https://forum.dd-wrt.com/phpBB2/viewtopic.php?t=9168

Found some old headlines about this option (you don't have to read them all):

Exploring ou currently used inadyn it seems

3322.org is no more - it became https://www.pubyun.com/
tzo.com, dynsip.org, dtdns.com also no more

https://github.com/troglobit/inadyn is a continuation of our in use inadyn 1.96
inadyn-mt is also a fork of the original 1.96 inadyn in use -- dd-wrt does not use inadyn-mt which our copy in tree is also severely outdated and no longer developed upstream and also still features support for outdated dead services.

All this to say, really looking at the source many mechanisms have been refactored and modernized if it is as small likely not, but Im sure after some stripping of man pages and other crap it would probably fit, I cant see it being updated but I have done my due diligence to inform our beloved leader.

It needs to be updated IMO, listing dead services is an easy fix from UI side the rest is more time consuming.

And I dont even use this, as usual my own interests of adding more useful stuff I do use take a back seat as I advocate for updating this sort of basic stuff.

Inadyn will not be updated due to the fact that there are dependencies which make it take more flash space. Sir egc asked thrice.

Is "src/router/inadynv2" the standard In-A-Dyn?

Should be obvious but yes, yes it is. By standard -- like I already said and to expand, this is the ONLY maintained fork of the original inadyn which we currently use.

BS said this is too bloated now and likely only higher end routers will get it, I notice that we can remove man pages and other crud and then set AC_ARG_ENABLE(reduced, foo ) which reduces binary size by removing some features and then compile time -lto will likely reduce it more.

We also wouldn't need plugins to support any extra services, so Im hopeful since our current has 4 deprecated dead services. https://svn.dd-wrt.com/ticket/7605

Thanks! DynDNS.org was no longer free as well, was using it back then.

I think both D-Link and Asus had own free DDNS for their customers.

All I know is T-mobile home internet uses their cell/mobile phone towers, and they have use doubled nat'ed w/ CG-NAT...

... and that the "external IP check: YES" does not function for me, as the code seems to be monitoring something other than my real external IP.

Other follow-up....
Running DD-WRT v3.0-r46750 giga (05/25/21). Of course DD-WRT never had this issue until I moved and had to find alternative connectivity... and wound up w/ cell phone tower internet b/c Century link is the only hard-wired option... offering $60/mo for 6↓0.5↑mbps speeds like it's 1999.

The next public dd-wrt build after -r50671 will have a brand new and improved inadyn 2.9.1, safe to assume not backward compatible configuration in some/all cases.

So if that doesn't work for you feel free to consult https://github.com/troglobit/inadyn documentation and if any issues persist consider opening a bug report upstream at their github or search existing reports, else open a new one there and provide necessary information and see what the dev/support help say.

You're welcome.
