Ipv6 ipset loadfile option error

hi, thank you for reply.

I was inspired by openwrt documention, forum topics and luci created firewall rules.

i haven't seen config string like this before
can you share link to documentation or forum topic please?
i'm a little bit scared to take your advice without double checking because i don't want to lose access to remotely managed router a second time ;.)

ps i tried without success

config ipset
	option name nov6
	option family inet6
	option match dst_net
	option loadfile /tmp/nov6.lst
	option enabled 1

config rule
	option name nov6
	option family inet6
	option ipset nov6
	option src lan
	option dest wan
	option target REJECT
	option enabled 1

root@openwrt:~# service firewall reload
/dev/stdin:5412:48-52: Error: datatype mismatch, expected IPv6 address, expression has type IPv4 address
meta nfproto ipv6 meta l4proto tcp ip6 daddr @nov6 counter jump reject_to_wan comment "!fw4: nov6"
~~~~~~~~~ ^^^^^

nov6.lst file consists of ipv6 subnets, a subnet per single string
2001:4860::/32
2001:4860:4864::/48
...
etc

i'm using fw4
