FAQ - How to block an IP version for data traffic?

It can be useful due to reasons of security to block an IP version (IPv4 or IPv6) for data traffic completely. Proceed as follows for this:

• Activate the IP filters (firewall) of the IP version to be blocked (menu Netfilter - page IP filter)
• Modify all IP filter rules such that they exclude the respective IP version; for example by entering the IP address only in the permitted IP version (menu Netfilter - page IP filter)
