Is there a clear guide how to run custom scripts on Stock Firmware?

[KnowsMuch]

I was hoping to do a couple things on the router that require custom scripts.

1. Dropping login attempts to the OpenVPN server from specific IP Blocks
2. Creating a Custom DDNS using NameCheap

Any advice would be appreciated.

Stock firmware doesn't support user scripts like Merlin does (i.e. firewall-start or openvpn-event).

I believe there's a way to trigger a script when the router starts up (using the USB mount event) but that's it.

On boot up, it runs a script named /jffs/.asusrouter (make sure it is executable. Beware that this seems to run early in the startup processing while other things are still firing-up. I've had unusual things happen. Basically, some things work and others don't. And some times things work that didn't before. Maddening!

I use it to add jobs to crontab, add lines to the hosts file, and other stuff.

I have started a swap file on a USB using a script in file: /jffs/post-mount You can put whatever you want in the script but it needs to begin with:
#!/bin/sh
and I would add a delay line next like:
sleep 5

To get it to work, in a terminal do:
nvram set script_usbmount="/jffs/post-mount"
nvram commit

When the router starts or you insert a USB drive the script will run.

If I understand this correctly, the /jffs/post-mount script would run every time a usb drive was inserted. I'm guessing that on a boot, if one or more usb drives were already connected, it would run for each? So for one-time changes, the script probably should use a lock file in /tmp/root (so it is cleared post reboot) or some other mechanism to prevent running again.

Tried setting up a script in latest stock firmware (3.0.0.4.388_33506 / ASUS TUF-AX4200) and it doesn't seem to work anymore. I set the "script_usbmount" nvram parameter and I can see it for a short time afterwards (with nvram get...), but it's being overwritten and commit doesn't seem to work. Any ideas?
