The STPro IEEE802.1D Transparent Bridging packet service (further
referred to as Bridging) offers complete protocol transparency and
has inherent configuration simplicity. Yet it provides excellent
forwarding performance.
The STPro RFC1483 Routed Ethernet packet service (also referred
to as MAC Encapsulated Routing (MER)) relies on standard IP
Routing for its forwarding. However, prior to output IP packets on
the DSL line they are wrapped in Ethernet frames.
By doing so there is no apparent difference for the remote access
server between frames sourced by a bridge and those sourced by
the STPro MER entity.
PPPoE is one of two popular mechanisms to get in touch with the
SP.
 Bridged PPPoE
By installing a PPPoE client application (provided by your SP.)
on your PC(s) and by using the STPro's bridge, connectivity
can be established.
 Routed PPPoE
PPPoE SP access can equally be accomplished by the
embedded PPPoE client of the STPro.
The other method to get in touch with the SP over the DSL line is
PPPoA.
 Relayed PPPoA
Similar to Bridged PPPoE this requires installation of a PPTP
dialin application (*) on your PC(s).
 Routed PPPoA
PPPoA SP access can equally be accomplished by the
embedded PPPoA dialin client of the STPro.
(*) Most popular OSs have a PPTP dialin application installed, e.g. Microsoft
DialUp Networking or support PPTP Tunneling software to be installed.
