"Firewall Rules" block or allow traffic based on IP and ports. If you need "URL filter", "application control" and so on, you need to check modules in "Access Policy".
Contents |
1 New Rule
New a firewall rule, descriptions:
- Interface: "LAN" or "WAN". WAN interface is invalid in bridge mode.
- Type: packet direction.
- "Inbound", packet targets to the NGF device.
- "Forward", packet being forwarded.
- Source IP: packet source ip address. You can define IP as "Any", "Single", "Range" and "Customize".
- For "Single", a single ip or subnet is allowed(for example: 192.168.1.10 or 192.168.1.0/24).
- For "Range", you need to input an ip range.
- Target IP: packet target ip address, can be "Any", "Single", "Range" and "Customize".
- Target Port: packet target port, can be a single port or a port range, Syntax:
- One port: 8000
- A port range: 8000:9000
- Multiple ports: 80 8000
- Port and ranges: 80 8000:9000
- Protocol
- All: means all protocols, including TCP, UDP, ICMP and other IP protocols.
- TCP+UDP: both TCP and UDP.
- Action:
- "Reject": the rejected clients will get a RST packet immediately.
- "Drop": packets will be dropped, the clients will wait for connection timeout.
- "Allow": allow packet
- You may use time, from-to and effective on to define a time period for this rule to be applied.
2 Customize IP
Upon "Customize", you can block ip, subnets, countries and regions, domains and domain categories. For domains, WFilter will add dns replied ip addresses into the deny/allow list.
IP, subnet or domain per line, for example:
192.168.1.1
192.168.1.0/24

3 Processing Order for Rules
Rules are always processed from the top of a list down, first match wins. Understanding this order is especially important. You may drag the re-order icon to re-order rules.
4 Advanced Settings
In "Advanced Settings", you can setup default policies for ZONEs. Two Zones(LAN and WAN) are supported in default.
