firewall address list question

RouterOS Beginner Basics
1

Hi, I noticed per the Advanced Firewall instructions page - https://help.mikrotik.com/docs/display/ROS/Building+Advanced+Firewall

That the address-lists has many single address to list entries for example:

add address=0.0.0.0/8 comment=“defconf: RFC6890” list=not_global_ipv4
add address=0.0.0.0/8 comment=“RFC6890” list=bad_dst_ipv4

my question is…why arent we just using multiple comma separated list names?

add address=0.0.0.0/8 comment=“foo” list=bad_dst_ipv4,not_global_ipv4

It appears to accept this config in my routerOS

Thanks

Perhaps in the CLI that is possible but correct in winbox it looks like one at at time.

Comma separated names are accepted, because there’s no reason why you shouldn’t be able to name your list “bad_dst_ipv4,not_global_ipv4”. But it doesn’t do what you think, it’s still only one list with this exact name.
