Issue with custom DDNS (start_ddns script)...?

[HHawk]

Hi guys,

First off; I am using afraid.org custom DNS solution.
And I followed the tutorial for it here:

Nov 30 15:35:57 watchdog: start ddns.
Nov 30 15:35:57 rc_service: watchdog 253:notify_rc start_ddns
Nov 30 15:35:57 custom script: Running /jffs/scripts/ddns-start (args: 125.125.125.125)

Nov 30 15:37:27 watchdog: start ddns.

Nov 30 15:39:27 watchdog: start ddns.
Nov 30 15:39:27 rc_service: watchdog 253:notify_rc start_ddns
Nov 30 15:39:27 custom script: Running /jffs/scripts/ddns-start (args: 125.125.125.125)
etc...

Apparently it's checking every 30 seconds...? I don't think this is normal behaviour?
I have no idea what I am doing wrong, or what's wrong here.

This how the script looks like, but I doubt anything is wrong with it...

#!/bin/sh

curl -k "https://freedns.afraid.org/dynamic/update.php?MY-PERSONAL-KEY" >/dev/null 2>&1 &

if [ $? -eq 0 ]; then
    /sbin/ddns_custom_updated 1
else
    /sbin/ddns_custom_updated 0
fi

The only thing I can think of which is wrong or causing the problems are the settings under: WAN > DDNS:

Enable the DDNS Client: Yes
Server: Custom
Host Name: my.customhostname.com (at afraid.org)
Forced refresh interval (in days): 1

I own two Asus routers (one for work and one for home), both have the same issue (though different hostname).

Any ideas?

Thank you for your time and answer(s).

Regards

Have you inserted 44 signs key here: MY-PERSONAL-KEY
Run this to get rid of any CR at end of line: dos2unix /jffs/scripts/ddns-start
Make sure you don't have .sh at end of ddns-start script
And run chmod a+rx /jffs/scripts/ddns-start to set file rights

EDIT: make sure you not are on double nat.

Done all that... Will redo everything on both routers again...
