Field
Description
Number of
IPs
This field is to specify how many IPs are provided by your ISP
for the current VC. You can select
Single
or
Multiple
. When
you choose
Single
, you can set
DMZ
or
Virtual Server
. When
you choose
Multiple
, You can set
DMZ
,
Virtual Server
or
IP
Address Mapping (for Multiple IP Service)
.
Note:
VCs with a single IP share the same DMZ and Virtual servers. For VCs
with multiple IPs, each VC can set DMZ and Virtual servers. Also, VCs
with multiple IPs can define the Address Mapping rules. VCs with a
single IP do not need to individually define the Address Mapping rule.
Demilitarized Zone (DMZ) is used to provide Internet services without
sacrificing unauthorized access to its local private network. Typically, the
DMZ host contains devices accessible to Internet traffic, such as web (HTTP)
servers, FTP servers, SMTP (e-mail) servers and DNS servers.
In the
NAT
page, choose
DMZ
, and the page shown in the following figure
appears.

DMZ
Host IP
Address
Enter the specified IP Address for the DMZ host on the LAN

In the
NAT
page, choose
Virtual Server
, and the page shown in the following
figure appears.
The Virtual Server is the server(s) behind NAT (on the LAN), for example,
Web server or FTP server, which you can make visible to the outside world
even though NAT makes your whole inside network appear as a single
machine to the outside world.
The following table describes the parameters of this page:
Field
Description
Rule Index
The Virtual server rule index for this VC. You can specify 10
rules in maximum. All the VCs with single IP will use the same
Virtual Server rules.

In the
NAT
page, select Number of IPs as
Multiple
, and then choose
IP
Address Mapping (for Multiple IP Service)
, and the page shown in the
following figure appears. The IP Address Mapping rule is per-VC based (only
for Multiple IPs' VCs).
Entries in this table allow you to configure one IP pool for specified source IP
address from LAN, so that one packet whose source IP is in range of the
specified address will select one IP address from the pool for NAT.
