3.4.1 NEW CONNECTION
A new connection is basically a virtual connection. Your Gateway can support up to 8 different (unique)
virtual connections. If you have multiple different virtual connections, you man need to utilize the static and
dynamic routing capabilities of the modem to pass data correctly.
3.4.2 BRIDGE GATEWAY PROFILE AND CONNECTION
A pure bridged connection does not assign and IP address to the WAN interface. NAT and firewall rules
are not enabled. This connection method makes the router act as a hub, and just passes packets across the
WAN interface to the LAN interface.
To configure the Gateway as a bridge, click on "New Connection" . At the Type field select Bridge and
the Bridge connection setup page is displayed (Figure 3.2). Give your Bridge connection a unique name; the
name must not have spaces and cannot begin with numbers. In this case the unique name is called bridge1.
Select the encapsulation type (LLC or VC); if you are not sure just use the default mode. Select the VPI and
VCI settings; your DSL service provider or your ISP will supply these; in this case the DSL service provider is
using 0,35.

3.4.3 PPPOA CONNECTION SETUP
PPPoA is also known as RFC 2364. It is a method of encapsulating PPP packets over ATM cells, which
are carried over the DSL line. PPP or Point-to-Point protocol is a method of establishing a network connection
/ session between network hosts. It usually provides a mechanism of authenticating users. LLC and VC are
two different methods of encapsulating the PPP packet. Contact your ISP to make sure which encapsulation is
being supported.
By selecting PPPoA, you are forcing your Gateway to terminate the PPPoA connection. The advantage is
that the PPPoA termination is done within the Gateway and not on your PC; this frees up your PC resources and
allows multiple users to utilize the PPPoA connection.
To configure the Gateway for PPPoA, click on Setup and then click on New Connection. At the Type
field select PPPoA and the PPPoA connection setup page is displayed; Figure 3.3 illustrates a typical PPPoA
