Help With DDNS

[lennshow66]

Hi Guys,

Im after some help in regards to how to set up a custom script for DDNS.

I have my ADSL modem which connects to my asus rt-ac68u router. I want to set my router up to update my domain name from namecheap so can access my IP camera outside the network.

I have figured out that I need to create a custom script as the WAN ip of my router is 192.168.1.100 (the modem).

I am having trouble writing this custom script as I have never done anything like this before.

I need to grab my external ip address and then update it to my domain. I need advice how I willl be able to do this. I have attached my code below.

Another problem im having is uploading the code to the router? How do I do this, im in the 'jffs/scripts/' folder on the router but cant figure out how to save my code to the router?

Thanks for any help you can give

#!/bin/sh
# Update the following variables:
HOSTNAME=@
DOMAIN=mydomain.com
PASSWORD=************************
IP=$(wget -qO - http://icanhazip.com)

# Should be no need to modify anything beyond this point
/usr/sbin/wget --no-check-certificate -qO - "https://dynamicdns.park-your-domain.com/update?host=$HOSTNAME&domain=$DOMAIN&password=$PASSWORD&ip="
if [ $? -eq 0 ]; then
  /sbin/ddns_custom_updated 1
else
  /sbin/ddns_custom_updated 0
