Aggressive mode IKE on VPN3K

Hello

I have VPN 3005 with 4.7.2 OS (a last to this day). I am trying to turn off the Mode aggressive treatment (stick to the main Mode only) for VPN clients to remove. Please note that remote VPN clients and NOT the LAN-to-LAN connections.

So far I don't see how this can be done.

TAC engineer is not to come up with more good responses.

In any case has an idea?

Thank you!

David

I don't think you can do the Remoting on VPN

the hub works with the main mode, unless

you decide to use the certificate instead of

pre-shared key:

"The Cisco VPN client uses main mode and aggressive mode pre-shared keys are used when the public key (PKI) infrastructure is used in Phase 1 of the tunnel negotiations. After wearing the Internet Security Association and Key Management Protocol (ISAKMP Security Association) Association Security upward for secure communications, Cisco VPN 3000 Concentrator prompts the user to specify the credentials of the user. In this phase, also known under the name X-Auth or extended authentication, the VPN 3000 Concentrator valid user on the database of authentication configured. If authentication success, the Cisco Concentrator sends a message of successful customer authentication. After X-Auth, the Cisco VPN client application configuration settings such as the assigned IP address, the domain name system (DNS) server IP address and the IP address of the Server Windows Internet Naming Service (WINS). During this phase, called mode-config, the VPN 3000 Concentrator sends the settings configured at the client. The final step for a VPN tunnel successful is negotiating the parameters of Phase 2.

    Hi Bill,

    Aggressive mode (3 pkt Exchange) is only used for remote access IPsec. The site to site VPN using main mode (6 pkt Exchange). If you don't have any VPN site to site, you can disable these commands but if you have VPN site to site then removing these will break them.

    There was nothing called aggressive mode in Anyconnect. AnyConnect uses a totally different protocol called SSL (port 443 TCP/UDP).

    Hope that answers your question.

  • Need for visibility on the IPsec protocol: aggressive Mode

    Hello

    I have a few doubts about VPN. I already went through a large number of documents. Everybody says something I don't agree with. So please don't view this kind of material in your answer.

    Aggressive mode: what I know, there are 3 Exchange for aggressive mode. Initiator in the first message sends the ID parameters, DH, HIS (IP address, domain name FULL). Then the answering machine (2nd MSG) reacts with the SA settings, DH, ID, HASH_R, then the initiator (3rd MSG) responds with HASH_I and PHASE 1 is established here.

    As the initiator and the responder IDs are sent in clear text, so we say that aggressive mode is not course.

    DH is used to exchange keys between peers. DH, negotiates and then generate a SECRET_KEY which in turn, is used to encrypt the symmetric key. We have SA parameters for encryption, hash, authentication.

    Here are my questions:

    (a) all of ITS parameters, IDs, DH traded first and second messages. The third message from the initiator is to send to HASH_I. Now, I don't see at all any use of DH in this mode, no encryption (payload ISAKAMP is not encrypted).  A single phase 1 aims to build a secure layer of management so that the PHASE connection 2 (data connection) may establish under a secure layer (PHASE 1). Now, I see that in aggressive mode we are not able to achieve this secure layer. So, what's the point of having encryption algorithms and DH in PHASE 1 if they are never used? Instead of skip PHASE 1 and we can have the PFS in Phase 2 for serving as a DH and we were hashing algorithms, encryption too.

    (b) the PRE SHARED KEY is actually shared via connect using the DH? Or just a HASH of PRE-SHARED-KEY is generated and sent on the connection for authentication?

    (c) why the aggressive mode can be used for dynamic addressing and not the main mode?

    If please answer queries and correct me if I am wrong somewhere.

    Thank you

    Rakesh Kumar

    (a). theoretically, jumping Phase 1 and done everything in Phase 2 (for aggressive mode only) would probably be a good idea to make it safer.  However, this would require a complete redesign of the IKE protocol.  As you probably already know, aggressive mode is used by default only for VPN remote access, and I've never seen used for a site to any of the customers that I came in contact.  In aggressive mode, in my opinion, would be used only in situations where a large number of VPN tunnels are built and demolished all the time (as with RA VPN) to save on material resources.  But... It is what it is, not a very safe to use method.

    (b) the pre-shared key is used to create a hash and this hash is sent to the remote peer.  If the remote peer can create the same hash using its own pre-shared key, then peers know they share the same secrets.  The problem with aggressive mode is that the hash is sent in plain text format, so if an attacker is able to capture these data they could preform a brute force offline attack.

    (c). I think that this has to do with the fact that the aggressive mode sends its identity in text clear and not must therefore not be pre-configured as a peer answer as it does with tunnels with addresses static at both ends.

  • Anyconnect Ikev2 uses aggressive Mode

    Hello world

    I'm trying to fix the IKE Aggressive mode with vulnerabilities PSK on our Cisco ASA that runs old IPsec and Ikev2 Anyconnect VPN.

    When I run the command

    Need to know anyconnect ikev2 does not share any key of share pre then why the number of line 17 shows AM (aggressive mode)?

    The ikev2 Protocol has nothing to do with the aggressive mode or main at all.

    If you do a 'sh crypto isa"it will show you the the ikev1 and his ikev2.

    If you still see a flow in the table, maybe it's a stuck session.

    To disable the aggressive mode, enter the following command:

    Crypto ikev1 am - disable

    For example:

    HostName (config) # crypto ikev1 am - disable

  • VPN in aggressive mode

    Hello

    Can someone tell me whatthe above message means and how to solve it.

    Thank you

    The command to disable connections inbound aggressive mode.

    If you want, there is an option to disable connections inbound aggressive mode on the tunnel-group as well.

    tunnel-group ipsec-attributes xxxxxx

    ISAKMP am - disable

    In this way you disable connections inbound aggressive mode to a specific peer.

    If a peer tries to establish a connection in aggressive mode, you should see a message like this in the logs:

    "Unable to initiate or respond to fashion aggressive while disabled"

    This command prevents Easy VPN Virtual Private Network (easy) clients to connect if they use of pre-shared keys because the easy VPN (hardware and software) customers use aggressive mode.

  • IPsec VPN Client - aggressive mode

    Hi all

    I just got got off the phone with the customer who underwent a check sweep of security from a third-party vendor. One of the vulnerebilities mentioned in the report is this:

    I know that only the IPsec VPN client using aggressive mode to negotiate Phase I. So my question is how to convince my customer to continue to use the IPsec VPN? Is this what can I do to reduce the risk of the use of this type of access remotely. In addition, am I saw the same problem, if I use SSL based VPN Client?

    Kind regards

    Hello

    Ikev1 HUB in aggressive mode sends his PSK hash in the second package as well as its public DH value.

    It is indeed a weakness of slope Protocol.

    To be able to act on this, U will be on the path to capture this stream in order to the brute force of the hash [which is not obvious - but not impossible.

    This issue is seriously attenuated by activating XAUTH [authentication].

    Xauth happens after the DH, so under encryption.

    Assuming that the strong password policy is in use, it is so very very very difficult to find the right combination of username/password.

    Ikev2 is much safer in this respect and this is the right way.

    See you soon,.

  • SRX5308 IPsec Config Mode - [IKE] ERROR: no configuration is found for...

    I have a real simple setup for Client-to-gateway VPN installation. Base tunnels seem to work fine, but when I try to install

    a policy of Mode Config I get an error in the connection and cannot ping resources on the local VPN network.

    The local IP address at the end of check-in Mode Config is 192.168.1.0. The manual says to leave the field empty and it will default to the address of the gateway, which is 192.168.1.1. If I leave the field blank this wrong address gets automatically enrolled and if I try to manually enter the right one I get an error saying it's an invaild address?

    Then when I connect, I get the following error:

    I think that is the question. How to work around this problem or do it properly? The manual is not any help and I googled my old brian dead.

    Thanks for any idea that you can give me!

    CC

    Thanks for the reply okadis and thanks for the link to this site, it is very useful!

    I was able to find a solution. Turns out that the works of very good firewall configuration. All I had to do was use the remote configuration of the CLIENT as the LAN address 192.168.1.0, and then everything worked.

    Now, for me, it's 2 "bugs" in the SRX5308 of Mode Config record:

    1 192.168.1.0 is not the address of the Local network subnet, it is 192.168.1.1; The manual says if left blank by default subnet LAN, which it isn't, it's default 192.168.1.0

    2. it won't let you enter ANY ip address here. It must be left blank.

    Maybe I'm missing something here, but it works perfectly after using what is there in the end customer.

    Should have been simple. Well...

  • iPsec gateway to gateway on LRT224, main mode?

    Hi, I just got my new Linksys LRT224

    I'm new to Linksys, but have used Netgear, D-Link and routers VPN Redfox.

    About 20 minutes after conversion unboxing of the LRT224 I have an iPsec tunnel of aggressive mode between my Netgear SRX5308 and the LRT224 work, very impressive I think, well not my performance but the ease of LRT224. Very nice interface easy to understand and quick Web. However, I noticed two things so far, 1 I can open only my SRX to the LRT224 tunnel and not vice versa. 2nd I can't get aggressive mode working on LRT224? I do something wrong or does the LRT224 not support the main mode?

    Someone else who tried the main mode?

    (there is no check box to select the main mode, but by selecting the name of domain + IP FQDN on local and remote in aggressive mode is not checked)

    I normally set up routers like this:

    Hi Ea > Br

    You can try it. Set the parameter to LRT224.

    As below:

    Configuration of the remote control groups:
    Remote security gateway type = IP + authentication with domain name

    Remote IP Type group = IP by DNS resolved:

    XXXX.dyndns.org

    Domain name = xxxx.dyndns.org

    The VPN tunnel will be working on the main mode, and you can open tunnel of LRT224 too.

    Hi Mike, the built-in client for MAC does not work with the RV220W. The reason is, the MAC IPSec client is the same as the Cisco VPN 5.x client.

    The reason that this is important is that the 5.x client work that on certain small business products include the SRP500 and SA500 series.

    I would recommend that you search by using a client VPN as Greenbow or IPSecuritas.

  • EzVPN between Cisco ASA 5505 (with NEM mode) and Ciscoo 881 Roure

    Hi friends,

    I configured the Cisco ASA 5505 and Cisco router with DMVPN 881. 3 offices works very well but one office remains failure. I did the same configuration for all facilities but this router does not work. Any ideas?

    Please find below the exit of 881 router Cisco:

    There is no DMVPN on the SAA. All that you have configured, is not compatible with the ASA or something another DMVPN then. At least debugging shows that there are some EzVPN involved.

    The debug version, it seems that there is no communication on UDP/500 possible between devices. Maybe something is blocking who?

  • Ports used in IKE Phase 1

    Hello world

    He had to confirm IKE Phase 1

    We use port UDP 500

    IKE Phase 2, we use ports

    ESP - 50

    NAT - T UDP 4500

    ESP TCP-1000-50
    NAT - T UDP 4500
    TCP-1000

    Concerning

    Mahesh

    IKE phase 1 (main mode/aggressive mode) is udp src and dst 500

    Phase 2 of IKE could be:

    • Protocol IP 50 (ESP)
    • NAT - T is udp src (customer) ephemeral dst (server) udp 4500
    • In former VPN clients tcp encapsulation was CBC (customer), ephemeral dst (server) tcp 10000 (10,000 in US) and 10,000 in most of the other countries

  • Pre shared keys used in IKE Phase 1

    Hello world

    Need to confirm if we use the buttons pre shared during IKE Phase 1 main mode and aggressive mode

    Concerning

    MAhesh

    The pre-shared key is used in both modes of IKE Phase I. With pre-shared keys, the same preshared key is configured on each IPSec peer. IKE peers authenticate each other computer and sending a hash key data that includes the pre-shared key.

  • 8.2 ASA failure phase2 ike ipsec

    I used the wizard to access remote vpn, IPSEC on an ASA 5510 security + running os version 8.2.

    When connecting using the client, it says «fixing communications...» "and then it flashes and it is disconnected. Hoping the following debug output to help you will help me, so I didn't enter the config.

    What seems to be the cause of failure of the phase 2 of IKE?

    IPSec driver successfully stopped

    Hello 3moloz123,

    Crypto ipsec transform-set esp-3des esp-md5-hmac TRANS_ESP_3DES_MD5

    Crypto ipsec transform-set transit mode TRANS_ESP_3DES_MD5

    Crypto ipsec transform-set esp-SHA-ESP-3DES-3des esp-sha-hmac

    1. the reason why the VPN remote access (RA) couldn't form with success before the passage of TRANS_ESP_3DES_MD5 to ESP_3DES_MD5 is the mode of transport is not supported for RA VPN.  You must use Tunnel mode for the processing of IPSec together we must maintain the IP header inside so that, once the package is decapsules and decrypted at the head of IPSec end we can transfer the package.

    In the newspapers, you can see this failure

    29 Dec 18:54: 26 [IKEv1]: Phase 2 failed: Mismatched types of class attributes Mode of Encapsulation: RRs would be: UDP Tunnel(NAT - T) Cfg had: UDP Transport

    Repeat x 4

    RRS of transformation all sent by the RA Client.  Cfg would be is that the dynamic encryption card supports.

    2. the isakmp policy change was unnecessary, the Phase 1 session came fine ISAKMP indicating worked.  Phase 2 begins only after a successful Phase 1 (session ISAKMP).

    After failing to build Phase 2 (child SA) we drop the ISAKMP Security Association since it is not used.

    I hope that answers your questions.

    Kind regards
    Craig
