GNUNET-NAT(1) General Commands Manual GNUNET-NAT(1)

NAME

gnunet-nat — interact with the NAT service

SYNOPSIS

gnunet-nat [-b ADDRESS | --bind=ADDRESS] [-c FILENAME | --config=FILENAME] [-e ADDRESS | --external=ADDRESS] [-i ADDRESS | --in=ADDRESS] [-r ADDRESS | --remote=ADDRESS] [-S NAME | --section=NAME] [-s | --stun] [-t | --tcp] [-u | --udp] [-W | --watch]

DESCRIPTION

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

OPTIONS

ADDRESS | ADDRESS
Assume that the service is (locally) bound to ADDRESS.
FILENAME | FILENAME
Use the configuration file FILENAME.
ADDRESS | ADDRESS
Assume that ADDRESS is the globally visible address of the peer.
ADDRESS | ADDRESS
Assuming we are listening at ADDRESS for connection reversal requests.
ADDRESS | ADDRESS
Ask the peer at ADDRESS for connection reversal, using the local address for the target address of the reversal.
NAME | NAME
Name of section in configuration file to use for additional options.
|
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.
|
Use TCP.
|
Use UDP.
|
Watch for connection reversal requests.

EXAMPLES

Basic examples

# gnunet-nat -i 0.0.0.0:8080 -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 -i 127.0.0.1:8080 -u

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

ICMP-based NAT traversal

# gnunet-nat -Wt -i 192.168.178.12:8080

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 -r 1.2.3.4:8080 -i 2.3.4.5:8080

# gnunet-nat -t -r 1.2.3.4:8080 -i 0.0.0.0:8080

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:

Manual hole punching

# gnunet-nat -t -p AUTO:8080

Assume manually punched NAT, but determine external IP automatically:

STUN-based XXX:

# gnunet-nat FIXME -s

XXX
