CONFIG Commands

Internet Key Exchange (IKE) Settings

The following four IPsec parameters conﬁgure the rekeying event.

set security ipsec tunnels name "123" IKE-mode

ipsec-soft-mbytes (1000) {1-1000000}

set security ipsec tunnels name "123" IKE-mode

ipsec-soft-seconds (82800) {60-1000000}

set security ipsec tunnels name "123" IKE-mode

ipsec-hard-mbytes (1200) {1-1000000}

set security ipsec tunnels name "123" IKE-mode

ipsec-hard-seconds (86400) {60-1000000}

•

The

soft

parameters designate when the system

begins

to negotiate a new key. For

example, after 82800 seconds (23 hours) or 1 Gbyte has been transferred (whichever

comes ﬁrst) the key will begin to be renegotiated.

•

The

hard

parameters indicate that the renegotiation

must

be complete

or the tunnel will

be disabled. For example, 86400 seconds (24 hours) means that the renegotiation

must be complete within one day.

Both ends of the tunnel set parameters, and typically they will be the same. If they are not

the same, the rekey event will happen when the longest time period expires or when the

largest amount of data has been sent.

Stateful Inspection

Stateful inspection options are accessed by the

security state-insp

tag.

set security state-insp [ ip-ppp | dsl ] vcc

n

option [ off | on ]

set security state-insp ethernet [ A | B ] option [ off | on ]

Sets the stateful inspection option

off

or

on

on the speciﬁed interface. This option is dis-

abled by default. Stateful inspection prevents unsolicited inbound access when NAT is dis-

abled.

set security state-insp [ ip-ppp | dsl ] vcc

n

default-mapping [ off | on ]

set security state-insp ethernet [ A | B ]

default-mapping [ off | on ]

Sets stateful inspection default mapping to router option

off

or

on

on the speciﬁed inter-

face.

set security state-insp [ ip-ppp | dsl ] vcc

n

tcp-seq-diff

[ 0 - 65535 ]

set security state-insp ethernet [ A | B ] tcp-seq-diff

[ 0 - 65535 ]

Sets the acceptable TCP sequence difference on the speciﬁed interface. The TCP

sequence number difference maximum allowed value is 65535. If the value of

tcp-seq-diff

is 0, it means that this check is disabled.

set security state-insp [ ip-ppp | dsl ] vcc

n

deny-fragments [ off | on ]

set security state-insp ethernet [ A | B ]

deny-fragments [ off | on ]

Sets whether fragmented packets are allowed to be received or not on the speciﬁed inter-

face.

set security state-insp tcp-timeout [ 30 - 65535 ]

Sets the stateful inspection TCP timeout interval, in seconds.

CONFIG Commands

set security state-insp udp-timeout [ 30 - 65535 ]

Sets the stateful inspection UDP timeout interval, in seconds.

set security state-insp dos-detect [ off | on ]

Enables or disables the stateful inspection Denial of Service detection feature. If set to

on

, the device will monitor packets for Denial of Service (DoS) attack. Offending packets

may be discarded if it is determined to be a DoS attack.

set security state-insp xposed-addr exposed-address# "

n

"

Allows you to add an entry to the speciﬁed list, or, if the list does not exist, creates the list

for the stateful inspection feature.

xposed-addr

settings only apply if NAT is off.

Example:

set security state-insp xposed-addr exposed-address# (?): 32

32 has been added to the

xposed-addr

list.

Sets the exposed list address number.

set security state-insp xposed-addr

exposed-address#

"

n

" start-ip

ip_address

Sets the exposed list range starting IP address, in dotted quad format.

set security state-insp xposed-addr

exposed-address#

"

n

" end-ip

ip_address

Sets the exposed list range ending IP address, in dotted quad format.

32 exposed addresses can be created. The range for exposed address numbers are from

1 through 32.

set security state-insp xposed-addr

Page 264 / 351

264

exposed-address#

"

n

" protocol [ tcp | udp | both | any ]

Sets the protocol for the stateful inspection feature for the exposed address list. Accepted

values for

protocol

are

tcp

,

udp

,

both

, or

any

.

If

protocol

is not

any

, you can set port ranges:

set security state-insp xposed-addr

exposed-address#

"

n

" start-port [ 1 - 65535 ]

set security state-insp xposed-addr

exposed-address#

"

n

" end-port [ 1 - 65535 ]

CONFIG Commands

SNMP Settings

The Simple Network Management Protocol (SNMP) lets a network administrator monitor

problems on a network by retrieving settings on remote network devices. The network

administrator typically runs an SNMP management station program on a local host to

obtain information from an SNMP agent such as the Motorola Netopia® Gateway.

set snmp community read

name

Adds the speciﬁed name to the list of communities associated with the Motorola Netopia®

Gateway. By default, the Motorola Netopia® Gateway is associated with the public commu-

nity.

set snmp community write

name

Adds the speciﬁed name to the list of communities associated with the Motorola Netopia®

Gateway.

set snmp community trap

name

Adds the speciﬁed name to the list of communities associated with the Motorola Netopia®

Gateway.

set snmp trap ip-traps

ip-address

Identiﬁes the destination for SNMP trap messages. The

ip-address

argument is the IP

address of the host acting as an SNMP console.

set snmp sysgroup contact

contact_info

Identiﬁes the system contact, such as the name, phone number, beeper number, or email

address of the person responsible for the Motorola Netopia® Gateway. You can enter up to

255 characters for the

contact_info

argument. You must put the

contact_info

argu-

ment in double-quotes if it contains embedded spaces.

set snmp sysgroup location

location_info

Identiﬁes the location, such as the building, ﬂoor, or room number, of the Motorola Neto-

pia® Gateway. You can enter up to 255 characters for the

location_info

argument.
