I've installed openwrt on my router from the repository and did sysupgrade.
After booting I added an ipset by in /etc/config/firewall using below lines:
option name 'test'
option match 'dest_net'
option enabled '1'
option loadfile '/etc/ipset/test.txt'
Also created a file in '/etc/ipset' named test.txt which includes:
After that I commited changes by "UCI COMMIT", then rebooted the router which caused the router to fail booting with blinking power (it seems it stuck at booting).
the only way to normal boot is to hard reset.
OpenWrt 22.03.2, r19803-9a599fee93 with default setting I did not even change the IP address.
What is the problem?
