DI-1162/DI-1162M Remote Access Router
11
Each WAN port can be configured to either receive dial-in calls (act as a Remote Access Server), dial out to other
routers (at branch offices or the Internet, for instance), or both (but not at the same time). The WAN ports can also
be configured for a leased line (synchronous) connection. Please note however that we recommend only one single
WAN connection to the Internet since a second connection will not significantly enhance the performance of the
connection.
Enabling a WAN Port
In this section, we will use WAN1 as an example. Other WAN ports however, will follow the same procedures.
1.
The WAN port must be enabled in the
Interface Configuration
submenu.
♦
Choose
Interface Configuration!WAN 1
.
♦
Configure the Protocol setting. This is a very important setting as it determines what type of device can be
connected to the WAN port.
◊
SLIP
Asynchronous mode used for modems.
◊
PPP_ASYN
Asynchronous mode used for modems.
◊
CISCO_HDLC
Synchronous mode used for CSU/DSU’s or synchronous modems
using a leased line.
◊
PPP_SYN
Synchronous mode used for CSU/DSU’s or synchronous modems using a
leased line.

FRAME_RELAY
A high-speed protocol available from many ISPs for switched lines.
The current version of this router only supports IP over frame relay and PVC. OSPF,
IPX, and bridge are not supported.
