Block traffic for some ip ranges

RouterOS Beginner Basics

Hello,

i want block all traffic from ranges below:

/ip firewall address-list
add address=192.168.0.80 list=block
add address=192.168.0.81 list=block

I use these rule:

/ip firewall filter
add action=drop chain=input src-address-list=block

Will that affect all IP ranges (192.168.0.80 + 192.168.0.81) ??

Also which is better:

/ip firewall filter add action=drop chain=forward dst-address-list=0.0.0.0/0 src-address-list=block

or

/ip firewall filter add action=drop chain=imput src-address-list=block
