+.SH "DESCRIPTION"
+.sp
+\fBanytun\-config\fR writes routing/connection table entries, that can be read by \fBanytun\-controld\fR\&.
+.SH "OPTIONS"
+.PP
+\fB\-L, \-\-log <target>:<level>[,<param1>[,<param2>[\&.\&.]]]\fR
+.RS 4
+add log target to logging system\&. This can be invoked several times in order to log to different targets at the same time\&. Every target hast its own log level which is a number between 0 and 5\&. Where 0 means disabling log and 5 means debug messages are enabled\&.
+
+The file target can be used more the once with different levels\&. If no target is provided at the command line a single target with the config
+\fBsyslog:3,anytun\-config,daemon\fR
+is added\&.
+
+The following targets are supported:
+.PP
+\fBsyslog\fR

+.PP
+\fB\-r, \-\-remote\-host <hostname|ip>\fR
+.RS 4
+This option can be used to specify the remote tunnel endpoint\&. In case of anycast tunnel endpoints, the anycast IP address has to be used\&. If you do not specify an address, it is automatically determined after receiving the first data packet\&.
+.RE
+.PP
+\fB\-o, \-\-remote\-port <port>\fR
+.RS 4
+The UDP port used for payload data by the remote host (specified with \-p on the remote host)\&. If you do not specify a port, it is automatically determined after receiving the first data packet\&.

+Resolv to IPv6 addresses only\&. The default is to resolv both IPv4 and IPv6 addresses\&.

+\fB\-R, \-\-route <net>/<prefix length>\fR
+.RS 4
+add a route to connection\&. This can be invoked several times\&.
+.RE
+.PP
+\fB\-m, \-\-mux <mux\-id>\fR
+.RS 4
+the multiplex id to use\&. default: 0
+.RE
+.PP
+\fB\-w, \-\-window\-size <window size>\fR
+.RS 4
+seqence window size
+
+Sometimes, packets arrive out of order on the receiver side\&. This option defines the size of a list of received packets\' sequence numbers\&. If, according to this list, a received packet has been previously received or has been transmitted in the past, and is therefore not in the list anymore, this is interpreted as a replay attack and the packet is dropped\&. A value of 0 deactivates this list and, as a consequence, the replay protection employed by filtering packets according to their secuence number\&. By default the sequence window is disabled and therefore a window size of 0 is used\&.

+SATP uses different session keys for inbound and outbound traffic\&. The role parameter is used to determine which keys to use for outbound or inbound packets\&. On both sides of a vpn connection different roles have to be used\&. Possible values are
+\fBleft\fR
+and
+\fBright\fR\&. You may also use
+\fBalice\fR
+or
+\fBserver\fR
+as a replacement for
+\fBleft\fR
+and
+\fBbob\fR
+or
+\fBclient\fR
+as a replacement for
+\fBright\fR\&. By default
+\fBleft\fR
+is used\&.
+.RE
+.PP
+\fB\-E, \-\-passphrase <pass phrase>\fR
+.RS 4
+This passphrase is used to generate the master key and master salt\&. For the master key the last n bits of the SHA256 digest of the passphrase (where n is the length of the master key in bits) is used\&. The master salt gets generated with the SHA1 digest\&. You may force a specific key and or salt by using
+\fB\-\-key\fR
+and
+\fB\-\-salt\fR\&.
