Help text

SNMP service requests are sent as broadcast messages from an unprivileged port and responded to with unicast messages to the same port. This make them hard to firewall properly because connection tracking doesn't deal with broadcasts. This helper tracks locally originating SNMP service requests and the corresponding responses. It relies on correct IP address configuration, specifically netmask and broadcast address.

To compile it as a module, choose M here. If unsure, say N.
