PPP Configuration Status will be displayed at the bottom
of this page to show all the Session Names with its [Adapter]
(PVC number), [Mode] ([PPPoA] or [PPPoE]), [Service Name],
[Account to Use] (PPP Account ID), [Disconnect Timeout]
configuration, [MRU], [MTU], [MSS], [Authentication Mode]
([Auto], [CHAP] or [PAP]), and [Auto Reconnect] configuration.
NAT Configuration
The [NAT Configuration] page allows the user to set the
configuration for the Network Address Translation. The default
setting is [Dynamic NAPT]. It provides dynamic Network Address
Translation capability between LAN and multiple WAN connections,
and the LAN traffic is routed to appropriate WAN connections based
on the destination IP addresses and Route Table. This eliminates
the need for the static NAT session configuration between multiple
LAN clients and multiple WAN connections.
When the [Dynamic NAPT] is chosen, there is no need to configure
the NAT Session and NAT Session Name Configuration.
NAT (Static) and NAPT (Static)
The [NAT] option only maps single WAN IP address to the local
PC IP address. It is peer-to-peer mapping. (1x1) For each WAN
interface, only one local PC IP address can be associated with
each WAN interface. Click the link [Session Name Configuration]
to add the session name for WAN interface.
The [NAPT] option maps the single WAN IP address to many
local PCs IP addresses. (1xN). It is the multiple-mapping
mechanism. For each WAN Interface, more than one local
PCs can be associated with one WAN Interface. Click the link
[Session Name Configuration] to add the session name for
WAN interface.
