The
NAT
option only maps single WAN IP address to the local PC IP address.
It is peer-to-peer mapping (1x1). For each PVC, only local PC IP address can
be associated with each WAN PVC. Even you can input more than one IP
address for one NAT Session, only the first IP address of each session takes
effect. Click the link
Session Name Configuration
to add the session name
for each PVC.
The
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 (1xN). It is the
multiple-mapping mechanism. More then one local PC can be associated with
one WAN PVC.
