如何在 prerouting 链增加自定义规则？

[digimoon]

参考官方教程修改了一下 https://openwrt.org/docs/guide-user/firewall/firewall_configuration

# /etc/config/firewall
config include
	option	type		'nftables'
	option	path		'/etc/my_custom_firewall_rule.nft'
	option	position	'chain-post'
	option	chain		'prerouting'
 
# /etc/my_custom_firewall_rule.nft
tcp dport 0-1023 log prefix "Inbound WAN connection attempt to low TCP port: "

想在 prerouting 链中再增加一些自定义的规则，但是完全没有生效，加到 mangle_prerouting 链倒是没有问题

系统版本是 23.05.5
