"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

[edit] 1 New Rule

Firewall set en.png

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: packet source. 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: packet target, can be "Any", "Single", "Range" and "Customize".
  • Source Port: packet source port, can be a single port or a port range,
  • 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
    • Empty matches all ports
  • 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.

[edit] 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

  • .imfirewall.com

[edit] 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.

[edit] 4 Advanced Settings

In "Advanced Settings", you can setup default policies for ZONEs. Two Zones(LAN and WAN) are supported in default.
