IP Multicast IP Multicast is used to send traffic to a specific group of computers. The
ZyXEL Device supports versions 1 and 2 of IGMP (Internet Group
Management Protocol) used to join multicast groups (see RFC 2236).
IP Alias IP Alias allows you to subdivide a physical network into logical networks
over the same Ethernet interface with the ZyXEL Device itself as the
gateway for each subnet.

your ZyXEL Device. You can also set the time manually. These dates
and times are then used in logs.

from the ZyXEL Device to an external UNIX syslog server.
