ASYNC ROUTER AR-P, AR-5, AND SYNC ROUTER USER’S MANUAL
53
A leased line is a type of phone service that offers a continuous connection between two sites,
typically at data rates of 56 Kbps (USA) or 64 Kbps (Europe). Leased lines are often referred
to as DDS lines (digital data service).
A non-leased line (switched), such as Switched-56, offers a high-speed dialup connection (typically 56
Kbps).
• Use as a backup?—For leased lines only, the analog modem (modem0) on the Sync Router can be
used to establish a second dialup connection to the same remote site. This second line would not
be used unless the sync0 port ceased to work correctly.
The analog modem can be used as a backup connection for leased lines, but not for non-leased
(switched) lines.
5.4.5 IP F
IREWALL PARAMETERS
Parameters specific to the IP firewall feature on Routers are listed here.
Do you want the firewall described in the documentation?
Answer yes if you want to install a list of IP filters designed to protect your network when the Router
is used to provide Internet access.
Public server IP address
Enter the IP address of the public server on the LAN connected to the Router.
Do you allow TELNET to the server (n):
If you want to allow telnet activities to your public server from outside of your network, enter “y” to this
question.
5.4.6 C
LIENT PARAMETERS
NOTE
If you have chosen to use a SecurID or RADIUS server, you do not have to configure
clients on the Router.
Client parameters are configured for each remote client. The Router gives you the option of using
Express Setup, to choose the following default values for access time, time quota, idle time, and no
callback:
• access time both inside and outside of the client access shift
• 1440 minutes time quota
• 240 seconds idle time
• no callback phone number (disabled)
To add many remote clients easily, with the default values above, use this faster method.
Express Setup assumes default values, so you enter only for each client: client name, client password,
and if the client is enabled. After you completely enter the data for one client, the Router prompts you
for another client. If you do not want to add more clients, enter n, and press RETURN. The Router
saves all remote client information on the diskette.
