About WFilter

2019-08-09T09:39:48Z

WFilter:

{{DISPLAYTITLE:WFilter Inside Technologies}}

= What is WFilter? =
WFilter is an internet monitoring and filtering software program that can help organizations to monitor and manage employees Internet behaviors in their networks. WFilter is available as a standalone product for Microsoft Windows, while it can also work with Microsoft ISA Server with full compatibility.

WFilter is a sniffer. All functions are based on network packets analysing. The main technologies of WFilter are the "Passby Filtering Technology" and the "Protocol Identify Technology". WFilter uses "Protocol Identify Technology" to recognise network applications and protocols, and uses "Passby Filtering Technology" to block unauthorized traffic.

== Protocol Identify Technology ==

"Protocol Identify" depends on network traffic analysing. WFilter does not indentify a protocol by ip address or port, but by digital signature matching. WFilter has a protocol signature database which is maintained by IMFirewall Software R&D team. When a new connection comes, WFilter will try to search the protocol database to get the protocol name. And common protocols even can be completedly parsed to get the content on transfering. To see a list of protocols supported by WFilter, please check the Protocols Supported by WFilter.

== Passby Filtering Technology ==

In "pass-by mode", WFilter uses "Passby Filtering Technology" to block Internet connections. A TCP connection can easily be destroyed by some fake packets. When unauthorized connections are detected, WFilter will send 1-2 packets to kill these tcp connections. That is called "Passby Filtering".

Benefits of using "Passby Filtering":

* If the Monitoring/Filtering machine goes down, the Internet connection stays alive.
* The computer can be taken down with no adverse affect on the network Internet connection, except that there's no monitoring or blocking.
* Does not hold Internet-bound packets, so it does not delay connection to Internet website.
* Eliminates unnecessary Internet requests, improving network performance.

The disadvantage of "Passby Filtering" is that it can not block UDP traffic, nor shaping bandwidth. To block udp traffic, you need to block certain ports in your router/firewall.

If you want a "pass-through filtering" solution to allocate and shape bandwidth, please check our [http://www.wfilterngf.com WFilter NGF].

Block udp

2019-08-09T09:37:42Z

WFilter:

= Introduction =

In "pass-by" deployment mode, WFilter can only block TCP traffic. To block UDP traffic, you also need to block certain UDP ports in your router or firewall.

For example:
* Tecent QQ works on udp 8000 by default, it also can use tcp ports 80 or 443 to connect when this udp port is not available. So for completely blocking of tencent QQ, not only you need block QQ in WFilter, but also need to block udp port 8000 in your router/firewall.
* When using chrome to access google/youtube sites, QUIZ(UDP port 443) is preferred. If QUIZ is not available, it will switch to normal http/https.

'''In "pass-by" deployment mode, you're recommended to block udp ports 443-65534 in your router or firewall.'''

== Examples of blocking udp ports ==

In this topic, we will list examples to block udp ports in router or firewall. If your WFilter is working in pass-through mode, you don't need to configure this. The IMNPTF driver will block udp traffic automatically in pass-through mode。

* [http://www.wfiltericf.com/support/WFilter_4_1/Doc/deployment_cisco_rv042_udp.htm Block udp ports in cisco RV042]
* [http://www.wfiltericf.com/support/WFilter_4_1/Doc/WFilter_cisco_2811_udp.htm Block udp ports in cisco 2811]

== Note ==
* You can add one simple rule to block udp ports 443-65534 in your router or firewall.
* Blocking of these udp ports won't block your internet access, except for a few applications.
* If an udp port is required, for example, application A needs to use UDP port "N". You can set your blocking ports ranges as: "443 -- (N-1)", "(N+1) -- 65534".
* Without blocking of these udp ports, WFilter are still workable except of possible incomplete blocking of some protocols(for example: QQ, skype, Bittorrent).

{{DISPLAYTITLE:Active directory Integration of WFilter}}

= Introduction =

"By ip address" and "by mac address" monitoring modes of WFilter enables you to filter internet activities by ip addresses or mac addresses. However, that's not enough in some networks.

For better internet monitoring and filtering, WFilter supports "Account Monitoring" to set policy based on user accounts. With this feature, you can set blocking policy for active directory users or WFilter local accounts.

This topic discusses "active directory integration of WFilter", "WFilter local users" and "terminal server solutions".

ERR NORECEIVEONBLOCK

2019-08-09T09:32:00Z

WFilter:

{{DISPLAYTITLE:Failed to send testing packets on the blocking adpater.}}

= Reason =

WFilter can not send packets via the blocking adapter.

= Solution =

In pass-by deployment, WFilter needs to send RST packets on the blocking adapter to terminate connections. However, some switches do not allow outgoing traffic on the mirroring port.

In this case, you need to add another NIC for blocking and communication. If your monitored devices number is more than 50, you're also recommended to use a separate blocking adapter.

Please check: [[WFilter_two_adapters|When shall you use two network adapters in the WFilter server?]]

ERR NOPACKETMONITORED

2019-08-09T09:30:06Z

WFilter:

{{DISPLAYTITLE:No packet can be monitored.}}

= Reason =

It's usually because incorrect monitoring adapter settings or the monitoring adapter is not supported.

Please notice that most wireless network cards are not supported.

= Solution =
* Check "System Settings"->"Monitoring Settings", to ensure the monitoring devices are properly configured.
* Ensure you're using a wired network card as the monitoring device.
* If you're not sure about the "IP Segments" settings, leave it as blank.
* If no adapter appears in the monitoring devices, please reinstall WFilter and reboot your windows to check.
