Difference between WFilter ICF and WFilter NG firewall.

Some users get confused about “WFilter ICF”(WFilter Enterprise) and “WFilter NG firewall”, so in this topic I would like to discuss the difference about these two products.

Though they are all named as “WFilter xxx”,  ”WFilter ICF” is a pass-by web filtering software for windows pc, while “WFilter NG firewall” is a linux-based firewall system which shall be installed in a dedicated x86 pc.

WFilter NG Firewall

  • 1. A total solution for bandwidth optimize, access control, VPN.(UTM and NG firewall)
  • 2. Deployment: gateway, bridge.
  • 3. Installation: x86 PC or virtual machine
  • 4. License: 30-day free trial

WFilter Internet Content Filter(ICF)

  • 1. Pass-by monitoring windows software solution.
  • 2. Recommend deployment: pass-by
  • 3. Installation: shall be installed in a windows PC.
  • 4. License: 30-day free trial

How to choose?

The first, you need to confirm your requirement. If you only need “internet access control”, both “WFilter ICF” and “WFilter NG firewall” can satisfy you. If you also need “bandwidth shaper” or VPN features, you need to choose “WFilter NG Firewall”.

The second, you need to choose the prefered deployment. In case you don’t want to change current network topology or add a new network device, you need to choose “WFilter ICF” which can be deployed with your current topology unchanged. If you agree to replace your current router/firewall, or add a transparent network bridge, please choose “WFilter NG firewall”.

The third, please be aware that WFilter ICF is a windows software program, which can be installed instantly. While WFilter NG firewall is an operation system, you need a dedicated PC and burn a CD or usb stick to install it.

Understanding the bandwidth shaper feature of WFilter NG Firewall

In a recent update of WFilter NG firewall, we have re-designed the “bandwidth shaper” feature. Now “bandwidth shaper” becomes easier to be understood and configured.

Let’s take a look.

The shaper rules list:

Ros ipcontrol 001.png

Bandwidth shaper policy:

Ipcontrol set en.png

In each policy, you need to define total UP and DOWNLOAD bandwidth for this rule. If this rule is applied to multiple clients, all the clients share the defined TOTAL bandwidth. Please note: “ the minimum bandwidth defines the static allocated bandwidth, while the maximum bandwidth is dynamic allocated.”

All clients applied by this rule have fair bandwidth sharing. You may also enable “client maximum rate” if you want to limit bandwidth rate for each IP.

In “ISP” module, the “Rate Limit” policy has the same settings as “bandwidth shaper”, as described in above.

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.

Wifi network monitoring solutions of WFilter NGF

Nowadays, most business networks provide WiFi service. However, WiFi makes it more difficult for IT administrator, because:

  1. There are much more devices in network.
  2. Various operation system(IOS, Andriod, Windows).
  3. Most wifi clients have dynamic ip addresses.
  4. Can not distinguish pc and mobile phone.
  5. Can not identify mobile users.

WFilter can help you to override these issues, and get your WiFi network manageable.
