8.3 Configuring IP Alias
IP alias allows you to partition a physical network into different logical networks over the
same Ethernet interface. The ZyWALL supports three logical DMZ interfaces via its single
physical Ethernet interface with the ZyWALL itself as the gateway for each DMZ network.
The IP alias IP addresses can be either private or public regardless of whether the physical
DMZ interface is set to use a private or public IP address. Use NAT if you want to make DMZ
computers with private IP addresses publicly accessible (see
information). When you use IP alias, you can have the DMZ use both public and private IP
addresses at the same time.
Note:
Make sure that the subnets of the logical networks do not overlap.
To change your ZyWALL’s IP alias settings, click
DMZ
, then the
IP Alias
tab. The screen
appears as shown.
Multicast
Select
IGMP V-1
or
IGMP V-2
or
None
. IGMP (Internet Group Multicast Protocol)
is a network-layer protocol used to establish membership in a Multicast group - it
is not used to carry user data. IGMP version 2 (RFC 2236) is an improvement
over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would like
to read more detailed information about interoperability between IGMP version 2
and version 1, please see
sections 4 and 5 of RFC 2236
.

Allow between DMZ
and LAN
Select this check box to forward NetBIOS packets from the LAN to the DMZ and
from the DMZ to the LAN. If your firewall is enabled with the default policy set to
block DMZ to LAN traffic, you also need to enable the default DMZ to LAN firewall
rule that forwards NetBIOS traffic.
Clear this check box to block all NetBIOS packets going from the LAN to the DMZ
and from the DMZ to the LAN.
Allow between DMZ
and WAN
Select this check box to forward NetBIOS packets from the WAN to the DMZ and
from the DMZ to the WAN.
Clear this check box to block all NetBIOS packets going from the WAN to the
DMZ and from the DMZ to the WAN.
