TTL
The TTL value (Time To Live) defines the lifetime of an IP packet.
Every router an IP packet passes through reduces the time to live value by one (1). If the
value is zero (0), the IP packet is discarded.
While preventing IP packets from endlessly circulating in the network due to routing errors,
this method stops IP packets from breaking through the limits of the LAN and being sent to
the WAN (TTL = 1).
According to requirements a TTL value from 1 – 255 can be entered. When entering 0
(zero), the default values are used (TTL = 1 for multicast, TTL = 64 for unicast).
