{{DISPLAYTITLE:HP A5120-24G port mirroring settings}}

HP A5120-24G port mirroring settings for WFilter.

== Defining source mirroring ports ==
system-view
mirroring-group 1
mirroring-port gigabitethernet 1/0/1 both

The source port to be monitored shall be connected to an uplayer device(for example: to the firewall/router, gigabitethernet 1/0/1).

== Defining target monitor port ==
system-view
mirroring-group 1
monitor-port gigabitethernet 1/0/2

The target port shall be the port connected to WFilter PC(gigabitethernet 1/0/2).

Now you shall be able to monitor all network traffic in WFilter.

WFilter IPBound

WFilter:

{{DISPLAYTITLE:WFilter IP-MAC binding solution}}

IP and mac binding is important to business networks. Without ip-mac binding, you can not identify clients or deploy internet access policies to correct clients.

You can do ip-mac binding in various ways:
* Configure static ip addresses in client devices, and forbid modifying.
* Assign static ip address in the DHCP server. Please note: clients can modify ip address manually.
* Configure port-based mac binding in switch.

The "ip-mac binding" feature of WFilter Enterprise can help you to check ip-mac binding. Clients will be blocked when ip-mac binding relationship is violated. This feature can work together with above solutions to prevent IP modifying.

[[image:ip-mac-binding01.png|800px]]

However, because WFilter Enterprise does not provide DHCP service. Please note:
* Do not enable IP-mac binding in WFilter in a DHCP network. Otherwise, clients will be blocked on ip changing.
* In a multiple-segment network, [[WFilter_Maccd|MAC address collector]] is required for ip-mac binding of multiple subnets.
* For a better IP-mac binding solution, please check: [http://wiki.wfilterngf.com/Ipbound IP-mac binding module of WFilter NG Firewall]

= How to enable port mirroring in cisco SF 300-24P switch =
To enable port mirroring, you need to access cisco SF 300-24P switch's web UI. And add a mirroring session in "Port and Vlan Mirroring":

[[File:Cisco_sf300_24P_port_mirror1.png]]

Please choose:

* 1. Type should be "Tx and Rx".
* 2. Destination port: the port directly connected to the WFilter pc.
* 3. Source interface: the port connected to router/firewall.

In this example, wfilter pc is connected to "FE1" port, while the uplayer router is connected to port FE2.

Block udp

2016-05-25T06:00:30Z

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).

You will get this message when WFilter detects a low blocking success rate. This indicates a deployment issue.

= Solution =

* If you have multiple VLANs, please make sure the blocking adapter of WFilter belongs to the "management vlan", which is able to reach other VLANs.
* Do not use a same blocking adapter as the monitoring adapter, please check: [[WFilter_two_adapters|When shall you use two network adapters in the WFilter server?]]

ERR NORECEIVEONBLOCK

2016-04-15T08:26:57Z

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.

{{DISPLAYTITLE:Can not get the gateway ip address.}}

= Reason =

In a multiple segments network, when this message appears, you won't be able to block clients in other subnets.

You can ignore this message if your wfilter server is the gateway.

WFilter:

{{DISPLAYTITLE:Packet loss rate is too high.}}

= Reason =

This message indicates:
* Incorrect port-mirroring configuration.
* Hardware issue of the port mirroring device.

= Solution =

* Do not mirror multiple source ports to a target port.
* Make sure the total source ports bandwidth will not exceed the target port's throughput.
* Though most switches allow outgoing traffic on a mirroring port, you're recommended not to allow large data transmission on the mirroring port. If you have to transfer large amount data with the monitoring server, please add another NIC to do that. Please check: [[WFilter_two_adapters|When shall you use two network adapters in the WFilter server?]]
* Packet loss also can happen when the mirroring switch has a hardware issue.

ERR NOPACKETMONITORED

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.
