Debian                                          October 26, 2018                                   GNUNET-NAT(1)

       This tool allows testing various NAT traversal functions, as well as attempting auto-configuration.

Basicexamples#gnunet-nat-i0.0.0.0:8080-u

       We are bound to "0.0.0.0:8080" on UDP and want to obtain all applicable IP addresses.

             #gnunet-nat-i'[::0]':8080-t

       We are bound to "::0" on port 8080 on TCP and want to obtain all applicable IP addresses.

             #gnunet-nat-i127.0.0.1:8080-u

       We are bound to "127.0.0.1:8080" on UDP and want to obtain all applicable IP addresses:

   ICMP-basedNATtraversal#gnunet-nat-Wt-i192.168.178.12:8080

       Watch  for  connection  reversal  request  (you must be bound to NAT range or to wildcard, 0.0.0.0), only
       works for IPv4:

             #gnunet-nat-t-r1.2.3.4:8080-i2.3.4.5:8080#gnunet-nat-t-r1.2.3.4:8080-i0.0.0.0:8080

       Initiate connection reversal request from peer at external IPv4 address 1.2.3.4, and let the kernel  fill
       in whatever IPv4 address we happen to have:

   Manualholepunching#gnunet-nat-t-pAUTO:8080

       Assume manually punched NAT, but determine external IP automatically:

   STUN-basedXXX:#gnunet-natFIXME-s

       XXX

       gnunet-nat — interact with the NAT service

-bADDRESS | --bind=ADDRESS
               Assume that the service is (locally) bound to ADDRESS.

       -cFILENAME | --config=FILENAME
               Use the configuration file FILENAME.

       -eADDRESS | --external=ADDRESS
               Assume that ADDRESS is the globally visible address of the peer.

       -iADDRESS | --in=ADDRESS
               Assuming we are listening at ADDRESS for connection reversal requests.

       -rADDRESS | --remote=ADDRESS
               Ask  the  peer at ADDRESS for connection reversal, using the local address for the target address
               of the reversal.

       -SNAME | --section=NAME
               Name of section in configuration file to use for additional options.

       -s | --stun
               Enable processing of STUN requests.  Will try to read UDP  packets  from  the  bind  address  and
               handle the packets if they are STUN packets.  Will only work with UDP.

       -t | --tcp
               Use TCP.

       -u | --udp
               Use UDP.

       -W | --watch
               Watch for connection reversal requests.

gnunet-transport(1)

       The  full documentation for gnunet is maintained as a Texinfo manual.  If the info(1) and gnunet programs
       are properly installed at your site, the command

             infognunet

       should give you access to the complete handbook,

             infognunet-c-tutorial

       will give you access to a tutorial for developers.

       Depending on your installation, this information is also available in gnunet(7) and gnunet-c-tutorial(7).
