Configuring IP Protocol
94 Perle 833IS User Guide
WAN The IP Protocol - WAN screen is as follows:
WAN Network
Address Clients dialing in to the 833IS must be assigned IP addresses on an Internal WAN
Network. This section defines the Internal WAN Network used by the 833IS and
should be completed after consulting with your IP Network Administrator. The
address of this Internal WAN Network must be different from the address of the
LAN segment network, although the Internal WAN Network may be a subnet of the
LAN segment network.
All dial-in client IP addresses, regardless of how they are acquired, must belong to
the network defined by this IP Address and Subnet Mask.
All dial in IP devices that are dialed into the WAN appear as if they are on their own
IP network. This network is referred to as the "Internal WAN Network". The 833IS
also requires one address on this network for the router port.
In general, it is recommended to define the Internal WAN network distinct from the
LAN network. It is possible to define the Internal WAN network as a subnet of the
LAN network, but there are limitations:
■
Routers on the LAN using RIP V1 cannot discover the Internal WAN network,
and will not be able to route to the dial in clients on the Internal WAN network.
■
DHCP is not supported for dial in clients in this mode.
