-When this option is enabled, the SPTPS protocol will be used when connecting to nodes that also support it.
-Ephemeral ECDH will be used for key exchanges,

.It Va ClampMSS Li = yes | no Pq yes
This option specifies whether tinc should clamp the maximum segment size (MSS)
of TCP packets to the path MTU. This helps in situations where ICMP
