Farallon Communications R9100 - Manual (Page 69)

WAN and System Configuration 8-9
Class A addresses are assumed to have a mask of 255.0.0.0
Class B addresses are assumed to have a mask of 255.255.0.0
Class C addresses are assumed to have a mask of 255.255.255.0. Class C address ranges are generally
the most common subnet allocated.
If a remote network has a non-standard mask (that is, it uses subnetting), the only way for it to successfully
connect to the Netopia Router is by matching a connection profile. In other words, you will have to set up a
connection profile for that network.If Must Match a Defined Profile is set to No, you can also set the
following parameters for accepted calls that do not match a connection profile:
Call acceptance scenarios
The following are a few common call acceptance scenarios and information on how to configure the Netopia
R9100 for those purposes.
■ To accept all calls, regardless of whether they match a connection profile:
■ Toggle Must Match a Defined Profile to No.
■ To only accept calls that match a connection profile through use of a name and password (or secret):
■ Toggle Must Match a Defined Profile to Yes, and
■ Set Authentication to PAP or CHAP.
Note: The authentication method you choose determines which connection profiles are accessible to
callers. For example, if you choose PAP, callers using CHAP or no authentication will be dropped by the
answer profile.
■ To allow calls that only match a connection profile’s remote IP and/or IPX address:
■ Toggle Must Match a Defined Profile to Yes, and
■ set Authentication to None.
System configuration screens
You can connect to the Netopia R9100’s system configuration screens in either of two ways:
■ By using Telnet with the Router’s Ethernet por t IP address
■ Through the console por t, using a local terminal (see “Connecting a console cable to your router” on
page 6-3 )
You can also retrieve the Netopia R9100’s configuration information and remotely set its parameters using the
Simple Network Management Protocol (see
“SNMP” on page 12-12 ).
Open a Telnet connection to the router’s IP address; for example, “192.168.1.1.”
