Outbound rules generally do not require configuration. Even when the firewall module is enabled, no outbound traffic will be blocked by default.

1. Important Notes

If the local IP and the destination IP are the same, the traffic is not restricted by the firewall, such as communication between the local machine and itself.

2. Execution Order

Rules are executed in order from highest to lowest priority. For rules with the same priority, they are executed in reverse chronological order of addition.

Priority range: 1-99 (1 indicates the highest priority, 99 indicates the lowest priority).

3. Filling Instructions
