Differences Between 833IS and Cisco Products
290 Perle 833IS User Guide
For IP, the 833IS looks like a router between two networks. The first network is
comprised of the devices on the LAN. The second network, referred to as the
"Internal WAN network", is comprised of all IP clients and routers that are dialed
into the WAN ports.
Setting up a basic 833IS IP configuration requires the following:
!
Defining the network on the LAN side, and defining the address of the LAN
router port.
!
Defining the network on the WAN side, and defining the address of the WAN
router port.
All clients dialed into the WAN, see the same address for this WAN router port.
!
Each client dialing in requires a unique IP address. The 833IS supports multiple
methods for defining and supplying IP addresses to clients.
If a router dials in to the WAN, the 833IS can route traffic from the dial in router to
the LAN. This feature is referred to as "LAN-to-LAN". Note that it is not possible
to route from this dial in router to a client or router on the Internal WAN network.
