Configuring IGMP (NSM Procedure)

On security devices, you must explicitly enable IGMP in Router mode on the interfaces that are connected to hosts. Security devices support the following Internet Group Management Protocol (IGMP) versions:

To enable IGMP in Router mode:

  1. In the NSM navigation tree, select Device Manager > Devices. Double-click the device object to open the device configuration.
  2. In the device navigation tree, select Network > Interface.
  3. Double-click the interface on which you are enabling IGMP. The General Properties screen appears.
  4. In the interface navigation tree, select Protocol.
  5. Select the IGMP tab and configure the following options:
    • In the Type box, select Router.
    • Select Enable.
    • Click OK to save your changes to the interface.
  6. Click OK to save your changes to the device.

You can optionally change the default parameters for each interface on which IGMP is enabled. You can also use access lists to control traffic to and from an IGMP interface. First, create access lists that identify the following items:

Then, enter the access list IDs in the IGMP configuration screen of the IGMP interface(s). The security device then filters IGMP traffic based on the access lists.
