NAME
       gnunet-nat-server - help GNUnet setup test network setup with NAT


SYNOPSIS
       gnunet-nat-server [options] PORT


DESCRIPTION
       Normal GNUnet end-users should not concern themselves with gnunet-nat-server.  In fact, distributions are
       encouraged to consider not shipping it  at  all.   Running  gnunet-nat-server's  is  similar  to  running
       hostlist  servers:  it  is a special service to the community with special requirements and no benefit to
       those running the service.

       This program will listen  on  the  specified  PORT  for  incoming  requests  to  test  a  peer's  network
       connectivity.   Incoming  requests  can ask it to connect to a given IPv4 address (and port) using TCP or
       UDP and to send a 2-byte test message using the specified address.  The program can also be asked to send
       a  "fake"  ICMP  response  message  to  a  given  IPv4  address (for autonomous NAT traversal --- see the
       description in the respective research paper).

       The idea is that gnunet-nat-server will be run on some trusted hosts with  unrestricted  connectivity  to
       allow  GNUnet  users  to  test  their network configuration.  As written, the code allows any user on the
       Internet to cause the gnunet-nat-server to send 2-bytes of arbitrary data to any TCP or UDP port  at  any
       address.  We believe that this is generally harmless.

       When  running  gnunet-nat-server,  make  sure  to  use a configuration that disables most NAT options but
       enables 'enable_nat_client' and sets 'internal_address' to the global IP  address  of  your  local  host.
       Also,  the  gnunet-helper-nat-client  should  be  installed  locally and run with root privileges (SUID),
       otherwise the gnunet-nat-server will not work properly.

       Note that gnunet-nat-server could be run via gnunet-arm but typically is not.  Also, the name of the host
       and  port  that  gnunet-nat-server  is  run on should be specified in the NATSERVER option in the [setup]
       section of the configuration file of hosts that are supposed to autoconfigure with this server.


OPTIONS
       -c FILENAME,  --config=FILENAME
              Use the configuration file FILENAME.
