Supported on the Cisco RV042 router settings

Hello

Anyone know if these settings are supported on router CiscoRV042

shared secret - authentication-

-AES-256 / SHA1 encryption

-IKE: Diffie-Hellman (Group 2)

-Phase 1 IKE every 1440 minutes.

-The phase 2 (IPsec) all 3600 sec (every hour) of IKE

Thank you.

These are all very standard parts of IPSEC.

IPSec configuration

So that any encryption occur, both ends of a

VPN tunnel must agree on the encryption methods,

decryption and authentication. This is done by sharing

a key for the encryption code. Key management, the

default mode is IKE with pre-shared key.

Overlay Mode Select IKE with pre-shared key or manual.

Both ends of a VPN tunnel must use the same mode of

key management. After selecting the mode, the

settings available on this screen may change depending

on the selection you have made. Follow the instructions

for the mode you want to use. (Manual mode is available

for VPN tunnels only, no VPN group.)

IKE with preshared key

IKE is used to negotiate Internet Key Exchange Protocol

for Security Association (SA) key material. IKE use it

Pre-shared key for authentication to the remote peer of IKE.

The phase 1 DH group Phase 1 is used to create the SA. DH

(Diffie-Hellman) is a key exchange protocol used for

Phase 1 of the authentication before establishing process

pre-shared keys. There are three groups of different premium

length of the key. Group 1 is 768 bits, and group 2 is 1024 bits.

Group 5 is 1 536 bits. If the network speed is preferred, select

Group 1. If it is better to network security, select group 5.

The phase 1 encryption select an encryption method: SOME

(56-bit), 3DES (168-bit), AES-128 (128-bit), AES-192 (192-

ILO) or AES-256 (256-bit). The method determines the

length of the key used to encrypt or decrypt ESP packets

AES - 256 is recommended because it is the safest.

Make sure that both ends of the VPN tunnel using the same

encryption method.

The phase 1 authentication select a method of

authentication, MD5 or SHA. The authentication method

determines how the ESP packets are validated. MD5 is

a one-way hash algorithm that produces a 128-bit

Digest. SHA is a one-way hashing algorithm which produces

a 160-bit digest. SHA is recommended because it is more

Fix. Make sure that both ends of the VPN tunnels using the

same authentication method.

Phase 1 life time sets the duration of a VPN

tunnel is active in Phase 1. The default is 28800

seconds.

Perfect Forward Secrecy if the perfect forward secrecy

(PFS) is enabled, the IKE Phase 2 negotiation will be

generate new key material for encryption of IP traffic and

authentication, then pirates using brute force to break

encryption keys will not be able to obtain future IPSec

keys.

Phase 2 DH group if the functionality of perfect forward secrecy

is disabled, then no new key will be generated, so you don't have

no need to adjust the Phase 2 DH group (the key for Phase 2

will be the key in Phase 1).

There are three groups of different main key lengths.

Group 1 is 768 bits, and group 2 is 1024 bits. Group 5 is

1 536 bits. If the network speed is preferred, select group 1.

If it is better to network security, select group 5. You do

no need to use the same group of DH that you used for

Phase 1.

Encryption of the phase 2 Phase 2 is used to create an or

several IPSec security associations, which are then used to key IPSec sessions.

Select an encryption method: NULL, (56-bit), 3DES

(168 bit), AES-128 (128-bit), AES-192 (192-bit) or AES-

256 (256-bit). It determines the length of the key used to

encrypt or decrypt packets ESP. AES-256 is recommended

because it is the safest. Both ends of the VPN tunnel

must use the same encryption of Phase 2 setting.

The phase 2 authentication select a method of

authentication, NULL, MD5 or SHA. Authentication

method determines how the ESP packets are validated.

MD5 is a one-way hash algorithm that produces a

Digest of 128 bits. SHA is a one-way hashing algorithm that

produces a 160-bit "Digest". SHA is recommended because

It's safer. Both ends of the VPN tunnel must use

the same Phase 2 authentication setting.

Phase 2 HIS life time sets the duration of a VPN

tunnel is active in Phase 2. The default value is 3600 seconds.

Pre-shared key that specifies the pre-shared key used

to authenticate the remote peer of IKE. Enter a key of

keyboard and hexadecimal characters, for example, [email protected]/ * /.

or 4d795f40313233. This field allows a maximum of 30

characters and hexadecimal values. The two ends of the

the VPN tunnel must use the same pre-shared key. It's

We recommend that you change the pre-shared

Key periodically in order to maximize the VPN security.

  • How to use Layer 2 Ports on the Cisco 1841 router switch

    Hello

    I use the Cisco 1841 router with a single port layer 3 Fe0 and 8 Ports switched.

    I gave the IP on the Fe0 port which is connected to another router.

    Now I don't know how to use Layer 2 of the router switch ports.

    I tried to make one of the port as a Port of access by switchport mode access and connected my laptop and the same subnet given IP, but I can't ping my Fe0 IP port and vice versa, as I am also unable to ping my laptop router.

    Can someone explain to me how to use these ports on layer 2?

    use a LAN switch for this or an etherswitch module installed in routers C2911

    routed ports can be used only routed or bridiging (IRB) ports, you cannot configure the as trunks of L2, you can use them as a L3 port channel but not as a port-channel trunk L2.

  • QoS is supported on the Cisco PIX 501 or 506th?

    Hello

    There is no mention of QoS in technical for the PIX 501 and 506 records but nothing for the 515. PIX OS 7.x configuration guides do not mention specific material support.

    Does anyone know if QoS is taken care of in the 501 or 506th - I need support lines expectations for VoIP over IPSec.

    Thank you

    QoS is supported in 7.x code, you would have to level 501/506 to 7.x code, but this is not supported on these two models, the next logical solution would be to upgrade your PIX 501/506 to asa5505s.

    Hello

    I just install the Cisco E2500 router and set up my wireless network.

    I bought the router hoping it would give me a more powerful than my old G Linksys 2.4 Ghz signal.

    Using inSSider I see my router and unfortunately it seems that both the 2.4 Ghz and 5 GHz range are both at the same time. I need help. The strength of the signal under RSSI is - 60 to-57 for the 2.4 Ghz and 5 Ghz range.

    I have to turn off one of these groups or what should I do to get a stronger signal?... my old Linksys router was to-50.

    Help... I'm not at all intuitive on routers, but I think that I would have only one band at a time or someother setting needs to be changed in order to improve my signal strength.

    Where we cut a band anyway?

    Any help would be appreciated.

  • Default configuration of the PFS on the Cisco ISR

    Hello

    I want to learn more about the default configuration of PFS on the Cisco ISR router.

    -Introduction to IP Security (IPSec) encryption - create a Crypto map
    http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_tech_note09186a0080094203.shtml#cryptomap

    You can also change the configuration of your PFS here. PFS Group1 is the default value in this example. You can change the PFS to group2, or turn off all together, you should not do.

    This example has no configuration PFS PFS is set to group1.
    However, the following command reference indicates that PFS is not requested.
    Which is the correct description for the PFS setting?

    By default, it is not required of PFS. If no group is specified with this command, the Group1 keyword is used by default.
    -------

    Thank you for your cooperation in advance.

    Order is correct.

    If pfs set is not configured in the crypto map configuration, pfs will be negotiated not.

    If set pfs is configured without any group, then it uses default group1

    And if you do not want to use the other group, you set the group # in the command set pfs.

    I hope it is clear now.

    I am running Windows Vista and the router is a Linksys E1000, version 2.  Is there a page on this site that tells me what to do?  I could not find.

    I thank very you much for any help you can give me.  I'm desperate!

    Thank you for your kind reply.  I did some reading and found that if I reinstalled the router, that would take care of the problem.  He did, and I'm back online!  I appreciate your response however!
