[-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
This tool allows testing various NAT traversal functions, as well as attempting auto-configuration.
- -b ADDRESS | --bind= ADDRESS
Assume that the service is (locally) bound to ADDRESS.
- -c FILENAME | --config= FILENAME
Use the configuration file FILENAME.
- -e ADDRESS | --external= ADDRESS
Assume that ADDRESS is the globally visible address of the peer.
- -i ADDRESS | --in= ADDRESS
Assuming we are listening at ADDRESS for connection reversal requests.
- -r ADDRESS | --remote= ADDRESS
Ask the peer at ADDRESS for connection reversal, using the local address for the target address of the reversal.
- -S NAME | --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
- -u | -udp
- -W | -watch
Watch for connection reversal requests.
# 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 18.104.22.168:8080 -i 22.214.171.124:8080
# gnunet-nat -t -r 126.96.36.199:8080 -i 0.0.0.0:8080
Initiate connection reversal request from peer at external IPv4 address 188.8.131.52, 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:
# gnunet-nat FIXME -s
The full documentation for gnunet is maintained as a Texinfo manual.
and gnunet programs are properly installed at your site, the command
should give you access to the complete handbook,
will give you access to a tutorial for developers.
