+The server configuration is complemented with host specific configuration (see
+the next section). Although all host configuration options for the local node
+listed in this document can also be put in
+@file{@value{sysconfdir}/tinc/@var{netname}/tinc.conf}, it is recommended to
+put host specific configuration options in the host configuration file, as this
+makes it easy to exchange with other nodes.

In this section all valid variables are listed in alphabetical order.
The default value is given between parentheses,
other comments are between square brackets.

@cindex DirectOnly
-@item DirectOnly = <yes|no> (no)
+@item DirectOnly = <yes|no> (no) [experimental]
When this option is enabled, packets that cannot be sent directly to the destination node,
but which would have to be forwarded by an intermediate node, are dropped instead.
When combined with the IndirectData option,
packets for nodes for which we do not have a meta connection with are also dropped.
@cindex Forwarding
-@item Forwarding = <off|internal|kernel> (internal)
+@item Forwarding = <off|internal|kernel> (internal) [experimental]
This option selects the way indirect packets are forwarded.
@table @asis
When this option is used the priority of the tincd process will be adjusted.
Increasing the priority may help to reduce latency and packet loss on the VPN.
+@cindex ReplayWindow
+@item ReplayWindow = <bytes> (16)
+This is the size of the replay tracking window for each remote node, in bytes.
+The window is a bitfield which tracks 1 packet per bit, so for example
+the default setting of 16 will track up to 128 packets in the window. In high
+bandwidth scenarios, setting this to a higher value can reduce packet loss from
+the interaction of replay tracking with underlying real packet loss and/or
+reordering. Setting this to zero will disable replay tracking completely and
+pass all traffic, but leaves tinc vulnerable to replay-based attacks on your
+traffic.
+
+
@cindex StrictSubnets
@item StrictSubnets <yes|no> (no) [experimental]
When this option is enabled tinc will only use Subnet statements which are
@file{@value{sysconfdir}/tinc/@var{netname}/hosts/} directory.
Setting this options also implicitly sets StrictSubnets.
+@cindex UDPRcvBuf
+@item UDPRcvBuf = <bytes> (OS default)
+Sets the socket receive buffer size for the UDP socket, in bytes.
+If unset, the default buffer size will be used by the operating system.
+
+@cindex UDPSndBuf
+@item UDPSndBuf = <bytes> Pq OS default
+Sets the socket send buffer size for the UDP socket, in bytes.
+If unset, the default buffer size will be used by the operating system.

Note that the IP addresses of eth0 and tap0 are the same.
This is quite possible, if you make sure that the netmasks of the interfaces are different.
