FIELD

DESCRIPTION

EXAMPLE

(Rem) IP
Subnet Mask

If you have a Static IP Assignment, enter the subnet mask assigned to
you.

Gateway IP
Addr

This field is applicable to Ethernet encapsulation only. Enter the
gateway IP address assigned to you if you are using a static IP
address.

My WAN
Addr

This field is applicable to PPPoE and PPTP encapsulations only. Some
implementations, especially the UNIX derivatives, require the WAN link
to have a separate IP network number from the LAN and each end
must have a unique address within the WAN network number. If this is
the case, enter the IP address assigned to the WAN port of your
ZyWALL.

Note that this is the address assigned to your local ZyWALL, not the
remote router.

Network
Address
Translation

Network Address Translation (NAT) allows the translation of an Internet
protocol address used within one network (for example a private IP
address used in a local network) to a different IP address known within
another network (for example a public IP address used on the Internet).

Choose None to disable NAT.

Choose SUA Only if you have a single public IP address. SUA (Single
User Account) is a subset of NAT that supports two types of mapping:
Many-to-One and Server.

Choose Full Feature if you have multiple public IP addresses. Full
Feature mapping types include: One-to-One, Many-to-One
(SUA/PAT), Many-to-Many Overload, Many- One-to-One and Server.
When you select Full Feature you must configure at least one address
mapping set!

See the NAT chapter for a full discussion on this feature.

SUA Only

(default)

Metric

Enter a number from 1 to 15 to set this route’s priority among the
ZyWALL’s routes (see the Metric section in the WAN and Dial Backup
Setup chapter) The smaller the number, the higher priority the route
has.

Private

This field is valid only for PPTP/PPPoE encapsulation. This parameter
determines if the ZyWALL will include the route to this remote node in
its RIP broadcasts. If set to Yes, this route is kept private and not
included in RIP broadcast. If No, the route to this remote node will be
propagated to other hosts through RIP broadcasts.
