.Qq any
is selected, then depending on the operating system both IPv4 and IPv6 or just
IPv6 listening sockets will be created.
-.Pp
-Mixing IPv4 and IPv6 may not work as desired.
-It's best to choose one address family and use that for all tinc daemons on the VPN.
.It Va BindToInterface Li = Ar interface Bq experimental
If your computer has more than one network interface,
.Nm tinc
It is possible to bind only to a single interface with this variable.
.Pp
This option may not work on all platforms.
-.It Va BindToIP Li = Ar address Bq experimental
-If your computer has more than one IP address on a single interface
-(for example if you are running virtual hosts),
-.Nm tinc
-will by default listen on all of them for incoming connections.
-It is possible to bind only to a single IP address with this variable.
-It is still possible to listen on several interfaces at the same time though,
-if they share the same IP address.
-.Pp
-This option may not work on all platforms.
.It Va ConnectTo Li = Ar name
Specifies which other tinc daemon to connect to on startup.
Multiple
This option controls the period the encryption keys used to encrypt the data are valid.
It is common practice to change keys at regular intervals to make it even harder for crackers,
even though it is thought to be nearly impossible to crack a single key.
+.It Va MACExpire Li = Ar period Pq 600
+This option controls the amount of time MAC addresses are kept before they are removed.
+This only has effect when
+.Va Mode
+is set to
+.Qq switch .
.It Va MaxTimeout Li = Ar period Pq 900
This is the maximum delay before trying to reconnect to other tinc daemons.
.It Va Mode Li = router | switch | hub Pq router
.It hub
This mode is almost the same as the switch mode, but instead
every packet will be broadcast to the other daemons
-while no routing table is created.
+while no routing table is managed.
.El
.It Va Name Li = Ar name Bq required
This is the name which identifies this tinc daemon.
Furthermore, specifying
.Qq none
will turn off packet authentication.
-.It Va IndirectData Li = yes | no Po no Pc Bq experimental
+.It Va IndirectData Li = yes | no Pq no
This option specifies whether other tinc daemons besides the one you specified with
.Va ConnectTo
can make a direct connection to you.

IPv6 subnets are notated like fec0:0:0:1:0:0:0:0/64.
MAC addresses are notated like 0:1a:2b:3c:4d:5e.
-.It Va TCPOnly Li = yes | no Po no Pc Bq experimental
+.It Va TCPOnly Li = yes | no Pq no
If this variable is set to yes,
then the packets are tunnelled over the TCP connection instead of a UDP connection.
This is especially useful for those who want to run a tinc daemon
