I am running Ver 384.18 of Asus Merlin on my router. I am trying to setup DDNS using freedns.afraid.org. I have created an account on freedns.org and have created the subdomain, but I am having a hard time understanding how to set this up on the Asus router. Specifically, what should be in the host name field?

The subdomain, in my case [xxxxxxxxxx.chickenkiller.com]

Although I'm sure the one posted above works fine, I used a different approach, one that I can also run on a number of other systems within my network (I'm also running double NAT so this works better for me)

Create a script: /jffs/scripts/ddns-start
chmod u+x /jffs/scripts/ddns-start


Contents of script (modify the "hash" to match the one for your account)
Code:
#!/bin/sh
curl --silent "https://freedns.afraid.org/dynamic/update.php?allhZmlxETkRDcEsksksXOjE5MDU5NDg5" > /jffs/scripts/ddns-start.log 2>&1
# reporting results to router
if [ $? -eq 0 ];
then
    /sbin/ddns_custom_updated 1
else
    /sbin/ddns_custom_updated 0
fi
