pls help me..thx

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.

vi /etc/config/firewall
root@OpenWrt:~# vi /etc/config/firewall

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

:warning: 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.

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

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