AX53U is in no way special than any other device running OpenWrt.
And guessing you're running either 22.03 or snapshot, you're not using iptables, but nftables.
First forum search result:

Working Nftables Rule for TTL in 22.03

After searching for updated nftable rules for TTL, I came across these links: 1.) put this in /etc/config/firewall config include option path '/etc/firewall.user' option fw4_compatible '1' 2.) create the file '/etc/firewall.user' 3.) put this line in it: nft add rule inet fw4 mangle_forward oifname usb0 ip ttl set 65 4.) restart the firewall /etc/init.d/firewall restart Not much info is available yet on fw4 and I am still waiting for updates on the gl.inet x750 and opal to be up…

Correct, that's how you edit the file. Not sure what "direct access" means otherwise.

If you attempted to execute the file instead, that's incorrect - it is a text file.

Are you following the link provided to you?

It says nothing about creating a user.

You'll need to be familiar with basic file editing and filesystem structure in order to complete these tasks.

Feel free to ask questions based on the TTL rule creation link provided. You can also ask there.
