Description
If this value is not empty, the host specified there
is used as the default gateway, which means that
all IP packets that cannot be directly assigned are
sent there for routing.
If DNS name servers are specified here (maximum
three), then they must be used to resolve symbolic
host names, i.e. at most of the points where an IP
address is expected, a computer name can also
be used instead.
The name server setting is also sent to its DHCP
clients (TCU, PG) via the DHCP server of the NCU,
so that they can also work with symbolic names.
Here you can specify up to three NTP servers
(UDP/123) that can be used by the NTPD on the
NCU for time synchronization.
