WFilter integrates with active directory — solution of content filtering with domain users.

Filtering by IP address and MAC address is enough for most networks. However, in networks with dynamic IP addresses or BYOD networks, you may not identify clients by IP or MAC. In this case, AD integration is a widely adopted solution for internet content filtering.

Both “WFilter Enterprise” and “WFilter NG Firewall” provides “AD integration” solution, which enables you to do reporting, monitoring and filtering with domain users.

1. AD Integration in “WFilter Enterprise”.

More details can be found at: Active directory Integration of WFilter Enterprise

2. WFilter NG Firewall

With WFilter NG Firewall, not only you can do “AD integration”,  you also can add “Local accounts” for monitoring, filtering and VPN access.

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.

  2. Nat discover: discover clients who are sharing their internet.plugin_nat_02_en

In general, we recommend:

    • a). Reasonable network topology, separate IP ranges of PC and WiFi.
