IPtables Configuration

 #
 # ipt_limit - this target allows for packets to be limited to
 # to many hits per sec/min/hr
 #
 # ipt_multiport - this match allows for targets within a range
 # of port numbers vs. listing each port individually
 #
 # ipt_state - this match allows to catch packets with various
 # IP and TCP flags set/unset
 #
 # ipt_unclean - this match allows to catch packets that have invalid
 # IP/TCP flags set
 #
 # iptable_filter - this module allows for packets to be DROPped,
 # REJECTed, or LOGged. This module automatically
 # loads the following modules:
 #
 # ipt_LOG - this target allows for packets to be
 # logged
 #
 # ipt_REJECT - this target DROPs the packet and returns
 # a configurable ICMP packet back to the
 # sender.
 #
 # iptable_mangle - this target allows for packets to be manipulated
 # for things like the TCPMSS option, etc.
 #CRITICAL: Enable IP forwarding since it is disabled by default since
 #
 # Redhat Users: you may try changing the options in
 # /etc/sysconfig/network from:
 #
 # FORWARD_IPV4=false
 # to
 # FORWARD_IPV4=true
