SLB™ Branch Office Manager User Guide

For Dial-back, the user will be authenticated via PAP or CHAP (configured with the
Authentication setting). For PAP, the Local/Remote list will be used to authenticate the login
and password sent by the PPP peer. For CHAP, the CHAP Handshake Host/User Name and
Secret/User Password will be used to authenticate the CHAP Challenge response sent by the
PPP peer. If the remote peer requests PAP or CHAP authentication from the SLB unit , the
Remote/Dial-out Login and Remote/Dial-out Password will be provided as authentication
tokens. Once authenticated, the SLB device will use the Dial-back Number configured for the
modem - either a fixed number assigned to the modem, or a number associated with the user
that was authenticated (the user must have Allow Dial-back enabled and a Dial-back Number
defined). If the SLB device can determine a dial-back number to use, it will hang up and wait
Dial-back Delay seconds before initiating the dial-back (if the dial-back fails, the SLB unit will
try Dial-back Retries times to dial-back). The SLB unit will dial, and if the remote peer requests
PAP or CHAP authentication, provide the Remote/Dial-out Login and Remote/Dial-out
Password as authentication tokens. Once authenticated, a PPP session will be established
using the Local IP and the Remote IP.
For Dial-on-Demand, the PPP connection will be established when it sees IP traffic destined
for the Remote IP. When this occurs, the SLBdials the Dial-out Number, and if the remote peer
requests PAP or CHAP authentication, provides the Remote/Dial-out Login and Remote/Dial-
out Password as authentication tokens. Once authenticated, a PPP session will be
established using the Local IP and the Remote IP. The PPP connection will stay active until no
IP traffic for the Remote IP is sent for Modem Timeout seconds. Once the timeout has expired,
the PPP connection will be terminated and will not be reestablished for at least Restart Delay
seconds.
Dial-In/Host List
The SLBwaits for a peer to call and establishes a text (command line) connection to the first host
in a Host List that connects. A host list of a prioritized list of SSH, Telnet or raw TCP hosts to
connect to. If Authentication is enabled for the Host List, the user will be prompted for a login and
password, and will be authenticated via the currently enabled authentication methods (Local
Users, NIS, LDAP, etc). Once authenticated, the SLBwill try to connect to each host in the host list
until a successful connection is established.
CBCP Server and CBCP Client
Callback Control Protocl (CBCP) is a PPP option that negotiates the use of callback where the
server, after authenticating the client, terminates the connection and calls the client back at a
phone number that is determined by the CBCP handshake. For more information on CBCP, see
http://technet.microsoft.com/en-us/library/cc957979.aspx
. CBCP is used primarily by Microsoft
PPP peers. CBCP supports two options for determining the number to dial on callback: the client
can specify a user-defined number for the server to dial on callback, or the client can request the
server use an administrator-defined number to dial on callback. Optionally, some servers may also
allow "no callback" as an option.
CBCP Server
The SLB unit waits for a client to call the it, establish a PPP connection, authenticate the user, and
negotiate a dial-back number with the client using CBCP. If the SLB unit is able to determine a
dial-back number to use, it hangs up and calls the dial-back number.
When a call is received, a PPP connection is established, and the user will be authenticated via
PAP or CHAP (configured with the Authentication setting). For PAP, the Local/Remote list will be
used to authenticate the login and password sent by the PPP peer. For CHAP, the CHAP
Handshake Host/User Name and Secret/User Password will be used to authenticate CHAP
