set ppp module [vccn] conﬁgure-max

integer

Speciﬁes the maximum number of unacknowledged conﬁguration requests that your Neto-

pia Gateway will send. The integer argument can be any number between 1 and 20.

set ppp module [vccn] terminate-max

integer

Speciﬁes the maximum number of unacknowledged termination requests that your Netopia

Gateway will send before terminating the PPP link. The integer argument can be any num-

ber between 1 and 10.

set ppp module [vccn] restart-timer

integer

Speciﬁes the number of seconds the Netopia Gateway should wait before retransmitting a

conﬁguration or termination request. The integer argument can be any number between 1

and 30.

set ppp module [vccn] connection-type

{ instant-on | always-on }

Speciﬁes whether a PPP connection is maintained by the Netopia Gateway when it is

unused for extended periods. If you specify

always-on

, the Netopia Gateway never shuts

down the PPP link. If you specify

instant-on

, the Netopia Gateway shuts down the PPP

link after the number of seconds speciﬁed in the

time-out

setting (below) if no trafﬁc is

moving over the circuit.

set ppp module [vccn] time-out

integer

If you speciﬁed a connection type of

instant-on

, speciﬁes the number of seconds, in the

range 30 - 3600, with a default value of 300, the Netopia Gateway should wait for commu-

nication activity before terminating the PPP link.

Conﬁguring Port Authentication.

You can use the following command to specify how

your Netopia Gateway should respond when it receives an authentication request from a

remote peer.

The settings for port authentication on the local Netopia Gateway must match the authenti-

cation that is expected by the remote peer. For example, if the remote peer requires CHAP

authentication and has a name and CHAP secret for the Netopia Gateway, you must enable

Page 267 / 351

267

CONFIG Commands

CHAP and specify the same name and secret on the Netopia Gateway before the link can

be established.

set ppp module [vccn] port-authentication

option [ off | on | pap-only | chap-only ]

Specifying

on

turns both PAP and CHAP on, or you can select PAP or CHAP. Specify the

username

and

password

when port authentication is turned on (both CHAP and PAP,

CHAP or PAP.) Authentication must be enabled before you can enter other information.

set ppp module [vccn] port-authentication username

username

The

username

argument is 1 – 255 alphanumeric characters. The information you enter

must match the username conﬁgured in the PPP peer's authentication database.

set ppp module [vccn] port-authentication password

password

The

password

argument is 1 – 128 alphanumeric characters. The information you enter

must match the password used by the PPP peer.

Ethernet Port Settings

set ethernet ethernet A mode { auto | 100M-full | 100M-full-ﬁxed |

100M-half-ﬁxed | 10M-full-ﬁxed | 10M-half-ﬁxed |

100M-half | 10M-full | 10M-half }

Allows mode setting for the ethernet port. Only supported on units without a LAN switch, or

dual ethernet products (338x). In the dual ethernet case, “ethernet B” would be speciﬁed

for the WAN port. The default is

auto

.

Command Line Interface Preference Settings

You can set command line interface preferences to customize your environment.

set preference verbose { on | off }

Speciﬁes whether you want command help and prompting information displayed. By

default, the command line interface verbose preference is turned off. If you turn it on, the

command line interface displays help for a node when you navigate to that node.

Page 268 / 351

268

set preference more

lines

Speciﬁes how many lines of information you want the command line interface to display at

one time. The lines argument speciﬁes the number of lines you want to see at one time.

The range is 1-65535. By default, the command line interface shows you 22 lines of text

before displaying the prompt:

More …[y|n] ?

.

If you enter 1000 for the

lines

argument, the command line interface displays information

as an uninterrupted stream (which is useful for capturing information to a text ﬁle).

CONFIG Commands

Port Renumbering Settings

If you use NAT pinholes to forward HTTP or telnet trafﬁc through your Netopia Gateway to

an internal host, you must change the port numbers the Netopia Gateway uses for its own

conﬁguration trafﬁc. For example, if you set up a NAT pinhole to forward network trafﬁc on

Port 80 (HTTP) to another host, you would have to tell the Netopia Gateway to listen for

conﬁguration connection requests on a port number other than 80, such as 6080.

After you have changed the port numbers the Netopia Gateway uses for its conﬁguration

trafﬁc, you must use those port numbers instead of the standard numbers when conﬁgur-

ing the Netopia Gateway. For example, if you move the router's Web service to port

“6080” on a box with a system (DNS) name of “superbox”, you would enter the URL

http:/

/superbox:6080

in a Web browser to open the Netopia Gateway graphical user interface.

Similarly, you would have to conﬁgure your telnet application to use the appropriate port

when opening a conﬁguration connection to your Netopia Gateway.

set servers web-http [ 1 - 65534 ]

Speciﬁes the port number for HTTP (web) communication with the Netopia Gateway.

Because port numbers in the range 0-1024 are used by other protocols, you should use

numbers in the range 1025-65534 when assigning new port numbers to the Netopia Gate-

way web conﬁguration interface. A setting of

0

(zero) will turn the server off.

set servers telnet-tcp [ 1 - 65534 ]

Speciﬁes the port number for telnet (CLI) communication with the Netopia Gateway.

Because port numbers in the range 0-1024 are used by other protocols, you should use

numbers in the range 1025-65534 when assigning new port numbers to the Netopia Gate-

way telnet conﬁguration interface. A setting of

0

(zero) will turn the server off.

☛

NOTE:

You cannot specify a port setting of

0

(zero) for both the web and telnet ports

at the same time. This would prevent you from accessing the Gateway.

Security Settings

Security settings include the Firewall and IPSec parameters. All of the security functionality

is keyed.

Firewall Settings (for BreakWater Firewall)

set security ﬁrewall option [ ClearSailing | SilentRunning |

LANdLocked ]

The 3 settings for BreakWater are discussed in detail on page

SafeHarbour IPSec Settings

SafeHarbour VPN is a tunnel between the local network and another geographically dis-

persed network that is interconnected over the Internet. This VPN tunnel provides a

secure, cost-effective alternative to dedicated leased lines. Internet Protocol Security

(IPsec) is a series of services including encryption, authentication, integrity, and replay pro-

tection. Internet Key Exchange (IKE) is the key management protocol of IPsec that estab-

lishes keys for encryption and decryption. Because this VPN software implementation is

built to these standards, the other side of the tunnel can be either another Netopia unit or

another IPsec/IKE based security product. For VPN you can choose to have trafﬁc authenti-

cated, encrypted, or both.

When connecting the Netopia unit in a telecommuting scenario, the corporate VPN settings

will dictate the settings to be used in the Netopia unit. If a parameter has not been speci-

ﬁed from the other end of the tunnel, choose the default unless you fully understand the

ramiﬁcations of your parameter choice.

set security ipsec option (off) {on | off}

Turns on the SafeHarbour IPsec tunnel capability. Default is off. See

“IPSec” on page 130

for more information.

set security ipsec tunnels name "123"

The name of the tunnel can be quoted to allow special characters and embedded spaces.
