hum, ok, so info in the Docs looks a bit misleading. At least to me!.
Anyways, I said I gave up on no-ip.com, but I guess I'll stick with it for now, until I don't get along with the setup.
Later, maybe I choose another one.
Also, I went to github for the latest /etc/config/ddns version and they say there to not use that file but a copy of it because all lines started with # and empty lines will be removed, as will be the options that I eventually set (uncomment) and they are already the default ones. I don't understand what they mean with "use a copy of this file". How will that change things? The content will be the same if I create a copy of the file.
Edited;
Nevermind, I got it.
I have tried to install ddns-scripts_no-ip_com and the first time I got an error, then I tried again and looks like it installed with no problems.
What happened???
# opkg install ddns-scripts_no-ip_com

I finally managed to get this working. But I still have a question. I'll first state how I managed to make it work and then I'll ask the question.
Steps:
1 - Install ddns-scripts
opkg install ddns-scripts
2 - Install additional package if needed (no-ip.com needs)
opkg install ddns-scripts_no-ip_com
3 - Replace file /etc/config/ddns-scripts with the most recent version from OpenWrt Github here.
Also keep the original name, just in case. I'm not sure if you can change the name.
4 - Change the following lines containing the following settings accordingly (downloaded file from step 3 is from 30/04/2020)
Line 66 config service "noip_ddns"
(service cannot contain white-spaces or dashes "-" or "@" ":" "!" or other special characters).
Line 73
option enable "1"
Line 79
option use_ipv6 "0"
Line 86
option interface "wan"
Line 107
Comment it out. This is only needed if an upate script is not provided by OpenWrt. NoIP script is provided, so not needed.
#option service_name "dyndns.org"
Line 115
Remove hash symbol. Uncomment. This is the location of the update script for NoIP, provided by OpenWrt.
Line 127
This is where you place the "url" so to speak, that you chose in your NoIP account to be pointed to by the IPs your PC is assigned with. For instance "my.chosen.domain.ddns.net"
option domain "my.chosen.domain.ddns.net"
Line 131 and 135
These are self explanatory. Your NoIP login credentials.
Last but not the least, restart ddns service with:
/etc/init.d/ddns restart
You can check it it is working by ping your my..chosen.domain.ddns.net from outside your local network and see if it gets 0% loss.
Are there any traces in the logs? Maybe it tells you where it connected?
If not then one way possible to check is to create a firewall rule to block tcp port 80 from any_zone to wan. Then I would trigger the DDNS service to see if it succeed updating your ip. Don't forget to unblock 80 afterwards.
And would that be right after restarting DDNS service or when? I want to avoid messing with the firewall because I don't feel comfortable with it and I can't afford to mess it up and lose internet connection.
From your configuration file, standard logging should occur in /var/log/ddns/myddns_ipv4.log and /var/log/ddns/myddns_ipv6.log. These are your config service '***' entries.
Maybe you need to manually set option use_syslog '1' (in config service '***'), then set it to 3 after you are done debugging.
But only the last one has today's date, so I think the other files are from previous failed attempts of me trying to configure the service as they have older dates.
In this last file this is what I can see with
tail -f /var/log/ddns/noip_ddns.log
220740 : Detect local IP on 'network'
220740 : Local IP 'xxx.xxx.xxx.xxx' detected on network 'wan'

221741 : Local IP 'xxx.xxx.xxx.xxx' detected on network 'wan'
221741 : Waiting 600 seconds (Check Interval)
I can't see anything related to SSL being used. What else can I do?
The second line, I have it since the very beginning the ddns service.
The first line I changed it today and reloaded ddns service. Should I restart the service instead?
When am I supposed to find anything there related to DDNS with SSL? Do you have idea of what kind of lines I am supposed to find? I have no idea what to look for!
I'm sorry, I really can't help you more. I don't even use DDNS on my OpenWrt, I was trying to point you to the right direction. I'm using it on my Synology instead.
All the information I gave you, I've got them using the forum. You need to search on the forum for DDNS Script Log, you'll find plenty of log samples, like this one:
Don't take it wrong, but someone with knowledge about this will need to chime in because I'm the blind who's walking the blind actually
@DjiPi I just got what I wanted but with the help of someone.
Let me say here how I was able to get it.
I think I was looking for more debug output than what the script and the service are prepared to output so I changed the variable VERBOSE to a value of 2 in /usr/lib/ddns/dynamic_dns_functions.sh because I see this line:
if [ ${use_logfile:-1} -eq 1 -o $VERBOSE -gt 1 ]; then
So, setting VERBOSE to any value greater than 1, gets me the following output:
122453 : sending real IP to 'no-ip.com'
122453 : #> /usr/bin/curl -RsS -o /var/run/ddns/noip_ddns.dat --stderr /var/run/ddns/noip_ddns.err --capath /etc/ssl/certs --noproxy '*' 'https://blablabla:***PW***@dynupdate.no-ip.com/nic/update?hostname=blablabla.ble.bli&myip=xxx.xxx.xxx.xxx'
122454 : 'no-ip.com' answered:
good xxx.xxx.xxx.xxx
122454 info : Update successful - IP 'xxx.xxx.xxx.xxx' send
122454 : Waiting 600 seconds (Check Interval)
Thank you.
I think I'll keep using this thread for upcoming tasks. I now want to do 2 other things. Setup a remote log so that I can save logs somewhere out of the router, in order to save space, and also setup DoT.
I will also want to get familiar with firewall settings. But that's another 500s.
Once more, trying to configure something in my OpenWrt.
I'm trying to redirect some traffic to allow SSH connections from outside. I've added the following to my /etc/config/firewall file, after saving a backup:
config redirect
option name 'OutToIn-SSH'
option src 'wan'
option dest 'lan'
option dest_ip '192.168.1.112'
option dest_port 'xxxxx'
option proto 'tcp'
option target 'DNAT'
And I also want to open 'xxxxx' port so I'm adding this, but not sure how to complete the section:
config rule
option name 'OpenPortSSH'
option src 'wlan'
option dest 'lan'
option dest_port 'xxxxx'
