PFsense 2.5.2 not updating DDNS hostname IP for NoIP and DynDNS

Schneizel1208

Hi,

No-IP was working well on 2.4.5 before my firewall suffered a catastrophic hardware failure. I had to reconfigure everything on 2.5.2 since it was the only available image from the official site. The re-setup was well, except for DDNS which I can't get it to work to this day.

I had tried this fix (https://redmine.pfsense.org/issues/12021) through System Patch package and manually edit the the dyndns.class file. Both did not fix the issue.

No-IP hostnames are working on my home firewall EdgeRouter6P.

I also started a trial account on DynDNS to see if a different service can solve the issue. But no, the issue is the same - firewall doesn't update the hostname IP.

At this point I am running out of ideas. Last resort is to factory reset the firewall to 2.4.5, but I've seen many have it working after patching the fix as detailed above.

I'm using pfSense 2.5.2 CE.

I just created a "pfsense-work.hopto.org" at no-ip. It's a free account.

My pfSense WAN IP is 82.82.82.82.

I used my phone to set some random IP like 92.184.108.24, my phone's IP.

I opened the pfSense DynDNS settings of this "pfsense-work.hopto.org" and did a "Save + Force update".

noip isn't signalling any errors in my case.
The IP update worked well.

It looks like, seeing the absence of any return data (the "Response Header" lines) you, that is pfSense, never managed to contact noip.

[2.5.2-RELEASE][admin@pfsense-work.net]/root: dig pfsense-work.hopto.org +short

after :

82.82.82.82

@gertjan Yes, The response header returned empty. Any way to fix this?

Fixing ?
It works for me.
That is : I use this :

That is de free no-ip account.

It works for me == not broken.
Using pfSense 2.5.2 CE.

@gertjan But it isn't working for me. Any idea why the response header is empty?

@schneizel1208

Not really.
The dyndns scripts use a classic 'curl' call - this simulates a web browser request.
The answer comes back as the return header, that should indicate "Response Header: HTTP/2 200" where "200" means : all ok.
"401", a well error result, indicates : the page you requested doesn't exist on the server.

Check the /etc/inc/dyndns.class - line 575 and afterwards.
This is this part of the 'code' where noip and noip-free is handled.

This is the URL :
https://dynupdate.no-ip.com/nic/update
To this URL are you added your user credentials.

You can use this URL in your browser :
I saw :

Keep in mind : if you - or some automated scrypt like dyndns.class, visits dynupdate.no-ip.com to often then that is considered as 'abusive' and your IP is blokced by their firewall. You couldn't connect to "dynupdate.no-ip.com" any more for a while. That would explain your issue.

Use another IP(WAN) and retest https://dynupdate.no-ip.com/nic/update
