 When enabled, tinc will decrement the Time To Live field in IPv4 packets, or the Hop Limit field in IPv6 packets,
 before forwarding a received packet to the virtual network device or to another node,
 and will drop packets that have a TTL value of zero,
 in which case it will send an ICMP Time Exceeded packet back.
