| Source zone | Any zone/LAN/WAN | LAN |
| Source MAC address | The source MAC address that matches this rule can be multiple MAC addresses. The MAC addresses are specified separated by spaces. The "Any" option matches all MAC addresses. Note: When matching the source MAC address, leave the source IP address blank. | Any |
| Source IP address | The source IP address that matches this rule can be in the form of an IP range, for example, 192.168.1.100-192.168.1.200. The "Any" option matches all IP addresses. Note: When matching the source IP address, leave the source MAC address blank. | Any |
| Source port | The source IP port that matches this rule can be in the form of a port range, for example, 8000-9000. The "Null" option matches all ports. | Null |
| Destination zone | Device/Any zone/LAN/WAN | Any |
| Destination address | The target IP address to match. The "Any" option matches all IP addresses. | Any |
| Destination port | The target port to match. The "Null" option matches all ports. | Null |
| Action | You can choose what action to take after receiving this type of data packets: drop, accept, reject, don't track. | Accept |
IP Address Blacklist
In the Traffic Rules menu, click the Add and edit button in the New forward rule section after entering a name (Name).
In the incoming interface, set Protocol to TCP+UDP, set the Source zone to lan, and set the Source IP address to the desired IP address. In this case, it was set to 192.168.1.163.
Set the Destination zone to wan, set the Destination address to any, and then set the Action to reject. Click the Save & Apply button.
As a result, the device with the IP address 192.168.1.163 has been denied access to external networks. You can add any traffic rules you want using the same logic.
IP Address Whitelist
In the Traffic Rules menu, click the Add and edit button in the New forward rule section after entering a name (Name).
In the incoming interface, set Protocol to TCP+UDP, set the Source zone to lan, and set the Source IP address to the desired IP address. For example, 192.168.1.150.
Set the Destination zone to wan, set the Destination address to any, and then set the Action to accept. Click the Save & Apply button.
Then, to deny all communication, add another rule with the Source IP address and Destination address values set to any, and the Action set to reject. In the order of the rules, the accept rule must come before the reject rule.
