You do not have to grant yourself rights.
You can observe the autogenerated rule that grants you maximum rights.
IP can be empty, meaning any IP will match.
You can use both IPv4 and IPv6. Some examples: 4.4.4.4, 1.2.3.0/24,
2001:6:3456::/64.
Priority is used to order the rights. They are evaluated top to bottom.
To add a deny rule, just do not select any right; if matched, the evaluation
of the next rules will stop.
