 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.
