6.6 LAN IP Alias
IP alias allows you to partition a physical network into different logical networks over the
same Ethernet interface. The ZyXEL Device supports three logical LAN interfaces via its
single physical Ethernet interface with the ZyXEL Device itself as the gateway for each LAN
network.
"
Make sure that the subnets of the logical networks do not overlap.
The following figure shows a LAN divided into subnets A, B, and C.
Figure 38 Physical Network & Partitioned Logical Networks
Use this screen to configure subnets on the LAN. Click Network > LAN > IP Alias . The
screen appears as shown.
MAC Address The MAC (Media Access Control) or Ethernet address on a LAN (Local Area
Network) is unique to your computer (six pairs of hexadecimal notation).
A network interface card such as an Ethernet adapter has a hardwired address
that is assigned at the factory. This address follows an industry standard that
ensures no other adapter has a similar address.
Reserve Select the check box(es) in each entry to have the ZyXEL Device always assign
the selected entry(ies)’s IP address(es) to the corresponding MAC address(es)
(and host name(s)). You can select up to 32 entries in this table.
Modify Click the modify icon to have the IP address field editable and change it.
Apply Click Apply to save your changes back to the ZyXEL Device.
