Weird firewall rule

Turris Omnia 4.0.3

In traffic rules list I found “Unnamed rule”. Seems like it is coming from following lines in /etc/config/firewall:

config rule 'turris_wan_6in4_rule'
        option enabled '0'

What is this rule about? Where did it come from? Should it be deleted or at least named properly?


See the very last one.

As it is disabled, you can ignore it in good conscience.
