DESCRIPTION

 

 

 

 

 

 

My WAN IP Address (or

Enter your WAN IP address in this field if you selected Use Fixed IP Address.

 

 

IP Address)

 

 

 

My WAN IP Subnet

Type your network's IP subnet mask.

 

 

Mask (Ethernet

 

 

 

encapsulation only)

 

 

 

 

 

 

 

Remote IP Address (or

Type the IP address of the remote network or gateway. The gateway is an

 

 

Gateway IP Address)

immediate neighbor of your ZyWALL that will forward the packet to the

 

 

 

destination. On the LAN, the gateway must be a router on the same segment as

 

 

 

your ZyWALL; over the WAN, the gateway must be the IP address of one of the

 

 

 

remote nodes.

 

 

 

 

 

 

Remote IP Subnet

When using a LAN to LAN application, type the IP subnet mask of the

 

 

Mask (PPPoE and

destination network. If you need to specify a route to a single host, use a subnet

 

 

PPTP encapsulation)

mask of 255.255.255.255, in the subnet mask field, to force the network number

 

 

 

to be identical to the host ID.

 

 

 

 

 

 

Network Address

Network Address Translation (NAT) allows the translation of an Internet protocol

 

 

Translation

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!

 

 

 

For more information about NAT refer to the NAT chapter in this User's Guide.

 

 

 

 

 

 

Metric (PPPoE and

This field sets this route's priority among the routes the ZyWALL uses.

 

 

PPTP only)

The metric represents the "cost of transmission". A router determines the best

 

 

 

route for transmission by choosing a path with the lowest "cost". RIP routing

 

 

 

uses hop count as the measurement of cost, with a minimum of "1" for directly

 

 

 

connected networks. The number must be between "1" and "15"; a number

 

 

 

greater than "15" means the link is down. The smaller the number, the lower the

 

 

 

"cost".
