Table 8-5 IP Setup
Enter the gateway IP address (if your ISP gave you one) in this field if you selected
Use Fixed IP Address.
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!
For more information about NAT refer to the NAT chapter in this User's Guide.
This field sets this route's priority among the routes the ZyWALL uses.
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".
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.
RIP (Routing Information Protocol) allows a router to exchange routing information
with other routers. The RIP Direction field controls the sending and receiving of RIP
packets.
Choose Both, None, In Only or Out Only.
When set to Both or Out Only, the ZyWALL will broadcast its routing table
periodically.
When set to Both or In Only, the ZyWALL will incorporate RIP information that it
receives.
When set to None, the ZyWALL will not send any RIP packets and will ignore any
RIP packets received.
By default, RIP Direction is set to Both.
