NAME

       fastd - Fast and Secure Tunnelling Daemon

SYNOPSIS

       fastd OPTION...

DESCRIPTION

       fastd  is  a  very  small  VPN  daemon which tunnels IP packets and Ethernet frames over UDP. It supports
       various modern encryption and authentication schemes and can be used in many different network topologies
       (1:1, 1:n, meshed).

OPTIONS

       --help, -h
              Shows a help text.

       --version, -v
              Shows the fastd version.

       --daemon, -d
              Runs fastd in the background.

       --pid-file <filename>
              Writes fastd's PID to the specified file.

       --status-socket <socket>
              Configure a socket to get fastd's status.

       --config, -c <filename>
              Loads  a  config  file.  - can be specified to read a config file from stdin. More than one config
              file can be loaded.

       --config-peer <filename>
              Loads a config file for a single peer. The filename will be used as the peer name.

       --config-peer-dir <dir>
              Loads all files from a directory as peer configs. On SIGHUP fastd will reload peer directories.

       --user <user>
              Sets the user to run fastd as.

       --group <group>
              Sets the group to run fastd as.

       --log-level error|warn|info|verbose|debug|debug2
              Sets the stderr log level; default is info if no alternative log destination is configured.

       --syslog-level error|warn|info|verbose|debug|debug2
              Sets the log level for syslog output; default is not to use syslog.

       --syslog-ident <ident>
              Sets the syslog identification; default is fastd.

       --hide-ip-addresses
              Hides IP addresses in log output.

       --hide-mac-addresses
              Hides MAC addresses in log output.

       --mode, -m tap|multitap|tun
              Sets the mode of the interface; default is TAP mode.

       --interface, -i <name>

       --bind, -b <address>[:<port>]
              Sets the bind address. Address can be an IPv4 address or an IPv6 address, or the keyword any. IPv6
              addresses must be put in square brackets.

              By default fastd will to bind to a random port for  both  IPv4  and  IPv6.  It  is  currently  not

       --protocol, -p <protocol>
              Sets  the  handshake  protocol.  Currently  the  only  protocol available is ec25519-fhmqvc, which

       --method <method>
              Sets the encryption method.

       --forward
              Enables forwarding of packets between peers; read the full documentation before use!

       --on-pre-up <command>
              Sets a shell command to execute before interface creation.

       --on-up <command>
              Sets a shell command to execute after interface creation.

       --on-down <command>
              Sets a shell command to execute before interface destruction.

       --on-post-down <command>
              Sets a shell command to execute after interface destruction.
