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?

HSRP support on the cisco SMB switches
Hello!
Just a question.
One of the Cisco Small Business L3 switches support the failover as HSRP, VRRP, and GLBP entry protocols?
Thanks in advance
Hi Dejan,
Oops, I overlooked the fact that you need L3 switches.
In this case, indeed the Catalyst 3560 would be the best choice.
Thank you for your trust to Cisco!

Ports 10/100/1000 on the cisco 2911 router does support etherchannel
Hello
I need like below

--------Trunk-------- 2911 Router 2911 Router-------Trunk-------------
-Ethernet point to point leased - Line2
I intend to use existing 3 onboard 10/100/1000 ports router 2911 for a configuration of trunk and etherchannel. Trunk connects to local lan conncts and etherchannel for remote sites. My doubt is can I configure 2911 as trunk ports on board and implement etherchannel? From now on, there will be no routing configuration in 2911.
Concerning
Siva K
Hi Siva,
> As of now, there is no routing configuration in 2911.
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
Chris
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.

Cisco Connect 'advanced settings '.
I have a Linksys E1000, firmware 2.1.02 Build 5. Everything works fine. I wish I could turn off and turn on Wi - Fi. I can't have a simple way of Cisco Connect to do. Is there a way?
Before installing Cisco Connect, I did it by browsing to 192.168.1.1, logging and the wireless tab, I chose 'Disabled' or 'Active '. Now, I think I need to go to Cisco Connect > router settings > change > advanced settings. But, he says: "... to change the advanced settings may prevent you from using Cisco Connect.
My question, if I turn off the Wi - Fi using the advanced settings of Cisco Connect, I eventually will be able to activate Wi - Fi using Cisco Connect advanced or I'd lose Cisco Connect altogether? Thank you.
Yes, it possible to disable, and then click Enable wireless by Cisco Connect. Cisco Connect will be still functional even after following the steps listed above. Later, when you want to enable wireless on your router, please ensure that you activate via Cisco connect itself.

Cisco RV042 VPN hub and spokes, connecting spokes question
Hello
I have a few Cisco RV042 router and VPN links them with a hub and spoke topology.
Each speaks VPN works, they manage to connect to the platform.
The hub can see each VPN active rays.
A computer under the hub can connect to a computer in any talks.
A computer under any talks can connect to a computer running the hub.
Which works very well.
Now, what I really need, is to connect computers under a RADIUS to connect to computers under another spoke.
It don't work.
Current configuration of LAN:
HUB IP / mask: 192.168.0.1 / 255.255.255.0
Spoke1 IP / mask: 192.168.1.1 / 255.255.255.0
Spoke2 IP / mask: 192.168.2.1 / 255.255.255.0
I was wondering if the Cisco RV042 can be configured to allow that and HOW?
If we can not do, should what other router I use as a hub? Should I change the rays as well?
Thank you and have a nice day
Hope that this document can point you the right direction.

E2500 Cisco's router dual-band
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.
Thank you
Tom.
Hi GV Expert,.
Thanks for your explanation as to what is measured and its relevance.
I would like to run the test that describe you.
First; When you say to connect my computer to a single band, I say - would allow a band to achieve this result?
In addition, how do you transfer a file, we are talking about transfer between my two computers?
Thank you for your patience and your help.

http://www.Cisco.com/en/us/Tech/tk583/TK372/technologies_tech_note09186a0080094203.shtml#cryptomapYou 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.
DT3-45 a (config) #crypto card armadillo 10 ipsec-isakmp

DT3 - 45's (config-crypto-map) #match address 101
--------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?-the pfs value
http://www.Cisco.com/en/us/docs/iOS/Security/command/reference/sec_s2.html#wp1063163Default values
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.

Need to know how to reconfigure the router settings
Hi - I was on the phone with technical support for an hour before, they told me they couldn't help me unless I paid or bought a new router. Isn't an option for me financially so I hope someone can help. :-(
My cable signal came out very briefly, probably for 5 to 10 seconds. When she came back, my router not working. I jumped through all the hoops reset that work normally, but nothing has worked this time. The tech guy said that I need to reconfigure my router settings. I don't know how. Can anyone here help me?
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!
