DI-1162 Remote Access Router
Configuration and Management 51
The Remote Access Configuration submenu is shown below. All items
in the submenu are described as follows.
Dial Configuration
You can configure the two WAN interfaces on your DI-1162 to
dial-out only when a packet is forwarded to that interface, and
hang up after all data has been transferred and the link is idle. This
can be used to lower the cost of an unpopular link or used as a
backup link to your ISP. This feature is commonly called “Dial on
Demand”. WAN interfaces can also be configured here to receive
calls from dial in users and other networks, called “Remote
Access”. Please note however, that in all cases, after configuring
the WAN interfaces in the
Dial Configuration submenu,
they must be further configured in the Dial-In User
Profile submenu or Remote Network Profile
submenu.
