NAME

       ndppd.conf - configuration file for ndppd

DESCRIPTION

       The syntax is as follows:

       proxy eth0 {
          rule 1234:5678::/96 {
          }
       }

       The  configuration file must contain one or more proxy sections, and each of these section
       must contain one or more rule sections.

       The ndppd daemon listens on the interface specified as an argument to the  proxy  section.
       Once  a  Neighbor  Solicitation  message  arrives, it will try to match the target address
       against the address specified as the argument of the rule section.

OPTIONS

       proxy <interface>
              Adds a proxy and binds it to the specified interface.  See  below  for  information
              about proxy options.

PROXY OPTIONS

       rule <address>
              Adds  a  rule  with  the  specified address to the proxy. It may be a an IP such as
              1234::1 or a subnet such  as  1111::/96.  See  below  for  information  about  rule
              options.

       ttl <value>
              Controls  how  long  ndppd  will  cache  an entry. This is in milliseconds, and the
              default value is 30000 (30 seconds).

       timeout <value>
              Controls how long ndppd will  wait  for  a  Neighbor  Advertisement  message  after
              forwarding  a  Neighbor  Solicitation  message  according  to  the rule. This is in
              milliseconds, and the default value is 500 (.5 second).

       router <yes|no>
              Controls if ndppd should send the router bit when  sending  Neighbor  Advertisement
              messages. The default value here is yes.

RULE OPTIONS

       Specify a method here. See below.

METHOD

       One  of  the  following  options  must  be specified in the rule section. All of these are
       mutually exclusive options, and cannot be combined.

       iface <interface>
              Specify which interface the Neighbor Solicitation message will be sent out through.

       auto   (NEW) If this option is specified ndppd will attempt to detect which  interface  to
              use  in  order  to  forward  Neighbor Solicitation Messages, by reading the routing
              table /proc/net/ipv6_route.

       static (NEW) This option tells ndppd that it should  immediately  respond  to  a  Neighbor
              Solicitation  Message  without  querying  an  internal  interface.   Note that it's
              recommended that you use this option sparingly, and with as high prefix  length  as
              possible.  This  is  to  make  sure upstream routers are not polluted with spurious
              neighbor entries.

              If no rule option has been specified, it will default to  static  in  order  to  be
              compatible  with 0.2.1.  This will, however, produce a warning, and most likely not
              work in future versions of ndppd.
