Planet Technology ADE-4000 user manual Nat, Dynamic Napt

System Configuration

Three types of NAT (Network Address Translation) service are provided by ADE- 4000.

NAT

NAT option only maps single WAN IP address to the local PC IP address. This is peer-to-peer mapping (1 on 1). For each PVC, only one local PC IP address can be associated with each WAN PVC. If more than one IP address is inserted for one

NAT session, only the first IP address of each session takes effect.

NAPT

NAPT option maps the IP address and UDP/TCP port ID of the WAN PVC to the IP address and UDP/TCP port ID of the local PCs. (1 to N). It is the multiple-mapping mechanism. More than one local PC can be associated with one WAN PVC.

The setting procedures are as follows:

Dynamic NAPT

Dynamic NAPT option maps the IP address and UDP/TCP port ID of the WAN PVC to the IP address and UDP/TCP port ID of the local PCs. (1 to N). It is the multiple-mapping mechanism, and it is dynamically allocated, this provides more functionality for Internet application under a NAT networking environment.

The setting procedures are as follows:
