Hello. I have a zyxel zywall usg 100 and would like to create a group which would be connected to a rule to block access or terminate the connection. This group would consist of IP addresses which I should be able to edit, thus add or remote public IP address that might be potentially harmful. Thank you.

Hi @cpg_juraj
Here is the example to group IP address
Go to Configuration > Object > Address >Address > click Add

Add two IP range into the rule

After added in to the rule, go to Configuration > Object > Address > Address Group > click Add

Select previous IP range to group the member.

Then can select the group IP address as destination in Firewall Rule

Hello. A wonderful tutorial. Thank you. Just one more clarification. If I want to block incoming traffic from the blocked IP addresses, would I create a rule with the "source" blockaddressgroup?
