Configuring IP Protocol
96 Perle 833IS User Guide
WAN IP Addresses Clients dialing in to the 833IS using the IP protocol need their own IP address. All
clients are assigned IP addresses on the Internal WAN Network that has a subnet
address distinct from the subnet address of the 833IS LAN port segment. The 833IS
will route packets between the LAN port segment and the Internal WAN Network.
The Perle 833IS can manage the client IP addresses using a number of different
schemes:
■ You can define an internal pool of IP addresses in the 833IS. A user dialing in
will be assigned an unused address from this pool.
■ If your network uses a DHCP server to manage IP addresses, the 833IS can
obtain an address for a dial in client from this server.
■ The client dialing in can provide the IP address.
■ You can configure an IP address for each user in the User database. If you are
using an external user database that supports the configuration of IP addresses
(such as RADIUS), the 833IS can use that address.
■ You can use a pool or server to get the IP address but allow the user to override
it if there is an address supplied by the user database or the client.
In all of the above cases, the IP addresses assigned to the dial-in client must be
within the range defined for the Internal WAN Network. See "Enter the IP address of
the Secondary WINS server. Blank indicates no Secondary WINS server." on page
104 for more details.
The following parameters control the assignment of the WAN IP addresses:
No Default
Select No default if you do not want to assign a WAN IP address from the internal
pool or a DHCP server.
DHCP
Select DHCP to use a DHCP server on your network to assign WAN IP addresses.
Use Internal Pool
Select Use Internal Pool if you wish to define an internal IP address pool. The IP
addresses will be assigned from this pool.
Allow Client Specified IP Addresses
When checked, the client supplied IP address will be used if available. This address
will override all other WAN IP addresses. (user database, internal pool or DHCP
server).
