5.2 Packet Services at a Glance
The AST570 supports two access methods:
Direct access
Once initial configuration is done, continuous and immediate
access is available via the DSL line.
For direct access use either of:
Transparent Bridging
Routed Ethernet
CIP & IP Routing.
Dialin access
In this mode access must be explicitly established, e.g. by
dialing" into a Remote Access Server (RAS).
For dialin access use either of:
Bridged PPPoE
Routed PPPoE
Relayed PPPoA
Routed PPPoA.
As their names imply the packet services can be differentiated in
two groups:
Forwarding packet services:
Transparent Bridging
Bridged PPPoE
Relayed PPPoA.
These packet services forward frames unmodified.
Routing packet services:
Routed Ethernet
Routed PPPoE
Routed PPPoA
CIP & IP Routing.
These packet services, combined with NA(P)T allow to share a
single IP address amongst multiple users on the (W)LAN.
