  23           Layer 3 independent connection tracking is experimental scheme
  24           which generalize ip_conntrack to support other layer 3 protocols.

 139           Packet filtering defines a table `filter', which has a series of

 162           which can effect how the packet is routed.

 204           Masquerading is a special case of NAT: all outgoing connections are
 205           changed to seem to come from a particular interface's address, and
 206           if the interface goes down, those connections are lost.  This is
 207           only useful for dialup accounts with dynamic IP address (ie. your IP
 208           address will be different on next dialup).
