Note that tinc will never use UDP with nodes that have
.Va TCPOnly
enabled.
-.It Va UDPDiscoveryInterval Li = Ar seconds Pq 9
-The minimum amount of time between sending UDP ping datagrams to test UDP connectivity.
+.It Va UDPDiscoveryKeepaliveInterval Li = Ar seconds Pq 9
+The minimum amount of time between sending UDP ping datagrams to check UDP connectivity once it has been established.
+Note that these pings are large, since they are used to verify link MTU as well.
+.It Va UDPDiscoveryInterval Li = Ar seconds Pq 2
+The minimum amount of time between sending UDP ping datagrams to try to establish UDP connectivity.
.It Va UDPDiscoveryTimeout Li = Ar seconds Pq 30
If tinc doesn't receive any UDP ping replies over the specified interval,
it will assume UDP communication is broken and will fall back to TCP.
+.It Va UDPInfoInterval Li = Ar seconds Pq 5
+The minimum amount of time between sending periodic updates about UDP addresses, which are mostly useful for UDP hole punching.
.It Va UDPRcvBuf Li = Ar bytes Pq 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.
.It Va PMTUDiscovery Li = yes | no Po yes Pc
When this option is enabled, tinc will try to discover the path MTU to this node.
After the path MTU has been discovered, it will be enforced on the VPN.
+.It Va MTUInfoInterval Li = Ar seconds Pq 5
+The minimum amount of time between sending periodic updates about relay path MTU. Useful for quickly determining MTU to indirect nodes.
.It Va Port Li = Ar port Pq 655
The port number on which this tinc daemon is listening for incoming connections,
which is used if no port number is specified in an
