|
| Network Address | Network Address Translation (NAT) allows the translation of an Internet |
|
| Translation | 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: |
|
|
| and Server. |
|
|
| Choose Full Feature if you have multiple public IP addresses. Full Feature |
|
|
| mapping types include: |
|
|
| Many Overload, Many- |
|
|
| 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 Prestige 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". |
|
| Private (PPPoE and | This parameter determines if the Prestige will include the route to this remote |
|
| PPTP only) | 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 Direction | 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 Prestige will broadcast its routing table |
|
|
| periodically. |
|
|
| When set to Both or In Only, the Prestige will incorporate RIP information that |
|
|
| it receives. |
|
|
| When set to None, the Prestige will not send any RIP packets and will ignore |
|
|
| any RIP packets received. |
|
|
| By default, RIP Direction is set to Both. |
|
|
|
|
|
| RIP Version | The RIP Version field controls the format and the broadcasting method of the |
|
|
| RIP packets that the Prestige sends (it recognizes both formats when |
|
|
| receiving). |
|
|
| Choose |

|
|

|
|
| they generally do not listen to the RIP multicast address and so will not receive |
|
|
| the RIP packets. However, if one router uses multicasting, then all routers on |
|
|
| your network must use multicasting, also. By default, the RIP Version field is |
|

| set to |
