Hi,
Maybe, the firewall address list is a way for the RBL.
For example, with an entry in the form cn.ascc.dnsbl.bit.nl source and destination can be prevented.
In this way, I want to make country-based blocking.
Best wishes.
It is possible to get all the IP addresses, which are assigned to the specific country.
Use excel to create .rsc file with all addresses, which will be added to the specific address-list.
