WFilter NG firewall has a built-in group “punish group”. With this punish group, you can add clients to the penalty box for a period of time.
Please note, “punish group” is a virutal group, you also can add your own virtual group, eg: “expired users” or “trial users”…
1. Add a client into the punish group.
In realtime bandwidth, by click “kill” icon in “connections”, you can add a client into the punish group for a period of time. Your own virtual group will also appears here.
2. Clients in the punish group.
3. Remove a client from the penalty box
To remove a client from the penalty box, you can wait for punish timeout, or click “reset default” in “unblock and reset”.
4. Set “access policy” and “bandwidth” policy for the punish group.
In “Access Policy” and “Bandwidth”, you can set policy for the punish group. For example, set “bandwidth shaper” for “punish group” to have only 20kb download rate limit.
To get it working, you need to use the “ntdsutil” tool to modify “MaxPageSize”. The below screenshot demonstrates the steps to set “MaxPageSize” to 5000. No reboot is required. The new setting is applied after “commit changes”.

Nowadays, most business networks provide WiFi service. However, WiFi makes it more difficult for IT administrator, as described in below:
- Much more devices in network.
- Various operation system(IOS, Andriod, Windows).
- Most wifi clients have dynamic ip addresses.
- Can not distinguish pc and mobile phone.
- Can not identify mobile users.
WFilter can help you to override these issues, and get your WiFi network manageable.
1. Identity Client Operation System
In “realtime bandwidth”, “online users” of WFilter, you can get a clients list, with IP, MAC, OS…
2. Various Authentication Solutions
- IP-MAC Binding, only bound ip-mac pairs have internet access. Please check: IP-MAC Binding
- Web Authentication, only authenticated users have internet access. Please check: Web Auth
3. Blocking, filtering and recording
You can set internet access policy by IP addresses, MAC addresses and usernames. In a DHCP network, you can set policy based on MAC addresses, so changing of IP has no influence.
In the recording feature of WFilter, you also can track internet usage( web activities, email activies) of Wi-Fi clients. Even mobile phone brand and model can be detected.
WFilter extentions also help for WiFi network mangement. For example:
- Network clients scan extension: scan the list of network clients.
- Nat discover: discover clients who are sharing their internet.
In general, we recommend:
- a). Reasonable network topology, separate IP ranges of PC and WiFi.
- b). IP bindings to WiFi clients or enable user authentication. Unauthorized access shall be forbidden.
- c). Use “nat discover” extension to forbid internet sharing.
