Class LocalRule

java.lang.Object
  com.esf.net.firewall.service.LocalRule

public class LocalRule
extends java.lang.Object

Creates an iptables command for a Local Rule, allowing an incoming port connection. CONFIGURATION Configuration will be accepted in the form of key/value pairs. The key/value pairs are strictly defined here: CONFIG_ENTRY -> KEY + "=" + VALUE KEY -> TYPE + INDEX + "_" + PARAM TYPE -> "LocalRule" INDEX -> "0" | "1" | "2" | ... | "N" PARAM (required) -> "port" | "protocol" PARAM (optional) -> "permittedNetwork" | "permittedMAC" | "sourcePortRange" VALUE -> (value of the specified parameter) EXAMPLE: LocalRule0_port=1234 LocalRule0_protocol=tcp LocalRule0_permittedNetwork=192.168.1.1 LocalRule0_permittedMAC=AA:BB:CC:DD:EE:FF LocalRule0_sourcePortRange=3333:4444
