VTI and crypto card

Hello

I wonder if it is possible to have a configuration in IPSEC tunnel, in which one side of the tunnel is configured with static VTI and the traditional second with crypto-map.

If so, how the configuration on the crypto-Map site should be configured.

Thank you in advance for an answer.

Concerning

Lukas

Lukasz,

This config is impractical for several reasons.

VTI dictates that a "any any" proxy set ID is negotiated. While this works well on a virtual interface, where routing can push traffic to a specific interface, it will make ALL traffic is encrypted on crypto maps side and expect all traffic is encrypted when it is recived (because crypto card is part of ECAS in the Lane exit).

A more practical approach in the world of Cisco is multi SA DVTI, where a DVTI can put end to any kind of insider tunnel (i.e. allow us DVTI to manage several SAs under a virtual interface) it works very well in some cases.

You can have DVTI on your end and allow the clients to use almost anything (from ASIT cryptographic maps).
I'll shoot you as an email at the same time, a bit stuck on something at the moment.

  • Site to Site VPN working without Crypto Card (ASA 8.2 (1))

    Hi all

    Find a strange situation on our firewall to ASA5540:

    We have a few Site to Site VPN and also activate on the ASA VPN cleint, all are working properly. But finding that a VPN from Site to Site is running without crypto map configuration. Is this possible?

    I tried to erase isa his and claire ipsec his then VPN came once again. Tested too, it's the ping requests to a remote site through the VPN.

    I saw there are config tunnel-group for VPN but saw no card crypto and ACL.

    How is the firewall knows what traffic should be encrypted for this VPN tunnel without crypto card?

    This is the bug?

    Thanks in advance,

    It can be an easy vpn configuration.

    Could you post output config operation remove any sensitive information.  This could help us answer your question more specifically.

  • 'Crypto card' to the in-house/internal interface. Possible?

    Hi, I have a two routers on a VPN to a point where the 'Crypto Map' statement is attributed to external as usual. It works fine but I need each router to a different IP address to the external interface.

    For example:

    crypto ISAKMP policy 1

    BA 3des

    preshared authentication

    life 3600

    privatekey key address 4.4.4.4 crypto ISAKMP xauth No.

    !

    !

    Crypto ipsec transform-set esp-3des esp-sha-hmac 3des

    !

    crypto map 1 VPN ipsec-isakmp

    defined peer 4.4.4.4

    Set transform-set 3des

    match the vpn address

    !

    interface FastEthernet0/0

    IP 4.4.4.4 255.255.255.252

    NAT outside IP

    IP virtual-reassembly

    10 speed

    full-duplex

    No cdp enable

    VPN crypto card

    !

    interface FastEthernet0/1

    IP 8.8.8.8 255.255.255.248

    IP nat inside

    IP virtual-reassembly

    automatic duplex

    automatic speed

    Instead of the "4.4.4.4" presented to the other side of the VPN, I need the 8.8.8.8 will be presented. I tried to change just the Crypto statements like below, but she always presents the 4.4.4.4 probably because of the interface that the Crypto map is applied

    crypto ISAKMP policy 1

    BA 3des

    preshared authentication

    life 3600

    privatekey key address 8.8.8.8 crypto ISAKMP xauth No.

    !

    !

    Crypto ipsec transform-set esp-3des esp-sha-hmac 3des

    !

    crypto map 1 VPN ipsec-isakmp

    defined peer 8.8.8.8

    Set transform-set 3des

    match the vpn address

    How can I make sure that 8.8.8.8 is what is presented on the other side?

    Thank you

    Andy

    Hi Andy,.

    I suggest the following command:

    card crypto-address

    http://Tools.Cisco.com/Squish/9c85B

    To specify and name an interface identify to be used by the encryption for IPSec traffic card, use the card crypto - local address in global configuration mode command. To remove this command from the configuration, don't use No form of this command.

    card crypto map-name - address interface id

    no card crypto name of the map address

    Example:

    interface loopback0

    IP 4.2.2.2 255.255.255.252

    !

    mymap-address loopback0 crypto card

    !

    S0 interface

    crypto mymap map

    !

    Of course, you need to make sure that the remote end can reach this additional IP address.

    Let me know if you have any questions.

    Please note any workstation that will be useful.

  • Multiple Crypto cards on simple external Interface

    Hi, I got the following encryption card configured on my ASA5505 to allow Cisco IPSec VPN clients to connect from the outside:

    crypto dynamic-map SYSTEM_DEFAULT_CRYPTO_MAP 65535 pfs Group1 set

    Crypto dynamic-map SYSTEM_DEFAULT_CRYPTO_MAP 65535 value transform-set ESP-AES-128-SHA ESP-AES-128-MD5 ESP-AES-192-SHA ESP-AES-192-MD5 ESP-AES-256-SHA ESP-AES-256-MD5 ESP-3DES-SHA MD5-ESP-3DES ESP-DES-SHA ESP-DES-MD5

    outside_map card crypto 65535-isakmp dynamic ipsec SYSTEM_DEFAULT_CRYPTO_MAP

    outside_map interface card crypto outside

    I'm now trying to set up a map of additional encryption - a static configuration to establish a tunnel with Windows Azure services. The configuration, they gave me is:

    Crypto map Azur-crypto-map 10 correspondence address azure-vpn-acl

    crypto azure-crypto-card card game 10 peers XXX.XXX.XXX.XXX (hidden)

    card crypto azure-crypto-map 10 set transform-set of Azur-ipsec-proposal-set

    Azur-crypto-card interface card crypto outside

    However, when I apply this configuration, my Cisco IPSec clients can connect is no longer. I think that my problem is that last line:

    Azur-crypto-card interface card crypto outside

    that blows away my original line:

    outside_map interface card crypto outside

    It seems that I'm stuck with just picking one of the maps to apply to the external interface. Is there a way to apply both of these cards to the external interface to allow the two IPSec tunnels to create? We lack ASA version 8.4 (7) 3.

    Hello

    You can use the same "crypto map"

    Just add

    card crypto outside_map 10 correspondence address azure-vpn-acl

    crypto outside_map 10 card game peers XXX.XXX.XXX.XXX (hidden)

    card crypto outside_map 10 set transform-set of Azur-ipsec-proposal-set

    Your dynamic VPN Clients will continue to work very well that their statements "crypto map" are in the order of precedence / low in "crypto map" configurations (65535) and VPN L2L is higher (10)

    And I want to say with the above is that, where a connection VPN L2L is formed from the remote end it will be naturally VPN L2L configurations you have with the number of configurations "crypto map" '10'. Then when a VPN Client connects it naturally will not match the specific configurations of the number "10" and will move to the next entry and the match (65535)

    If you happen to set up a new connection VPN L2L then you might give him the number "11" for example and it would still be fine.

    Hope this helps

    Hello:

    Your model does not include built in bluetooth network.

    The Atheros wireless network adapter is only wireless, not an adapter without wireless/bluetooth combination.

    You need this driver for the SD card reader...

    This package contains the driver that allows the Realtek card reader in laptop models running a supported operating system. The card reader allows users to read or write to removable storage cards supported, which are typically used in digital cameras, digital music players and cell phones.

    Please help me make my card reader works again.
    Concerning

    Post edited by: domaking

    For me, the matter is simple, and the reason why the SD card reader is not working, it's just a driver compatible isn't installed.
    My theory seems to be correct, given that the SM bus controller and PCI simple communication controller appear in Device Manager and I suppose that one of these devices belongs to the player/controller of the SD card.

    I think that you should simply install this Realtek card reader controller that I found on the page of the Toshiba UE driver
    http://Support1.toshiba-tro.de/Tedd-files2/0/CARC-20130924161048.zip

    In addition, you must install all the other drivers Win 7 as well as Toshiba tools available by Satellite C850 series.

    Very important is the chipset driver, USB 3.0 driver (Win 7 has this port driver to control the USB 3.0), display driver. etc.

    Not very essential tools are Bulletin Board, product information online Reeltime, etc. This tools additional don t improved the performance of the laptop so its up to you if you want to use these software components

    Hello

    I want to say clearly that portable computers technology design is not the same as on the desktop and if you have a good experience with desktop computers, you'll know that upgrading the graphics cards is not so problematic, but on laptops, the situation is very different.

    Laptops design and construction doesn't allow such flexibility for upgrades, upgrading the graphics card is not possible.

  • Satellite P300 - 220 (PSPCCE) and express card FireWire

    I have problems with an IRQ that is shared between the firewire (IEEE1394) and ati mobility radeon 4600. (the IRQ used by both devices is 16)
    Sharing this make my firestudio presonus (external FireWire sound card) problems when playing music on my DAO.

    I would buy an Express card for this problem, but I have to be sure that it won't be the same IRQ (16) than the other firewire connection.

    If you use such a card please check wich IRQ is used when it is connected on the laptop.
    You can see with Device Manager.

    Thank you very much.

    Hello

    The Windows operating system controls and assigns automaticity all remedies to all controllers!
    In my case the SD host controller and the graphics card share the same IRQ 16 and there is NO conflict.
    So I doubt that your problem is related to the same IRQ which is used by firewire and graphics card.

    Sorry, but that's all I can suggest about your question

  • 9174 OR with 2 cards 9233 and 1 card 9234

    I want to use a 9174 OR-DAQ with 2 cards 9233 and 1 card 9234, 9233 card allows us to sample up to 50 kech. / s and the 9233 up to 51.2 kech. / s. Now, we start the sampling at the same time. We work with 12 microphones, four in each card. It does not matter if each card samples at a different pace, we only need the highest possible in all cases. The problem is that we have not found a way to do this with the DAQ 9174 materials. When you have completed a task of sampling, it seems that sampled to 51.2 kech. / s with all cards, even with the 9233. What can we do to accomplish this task? Thank you in advance.

    Hi Luis,.

    You see the expected behavior.  As you have noted, the 9233 has a maximum rate of 50kS/s and the 9234 a maximum rate of 51.2 kech / s but that's only what they are capable of using their internal time base.  The 9233 specifies a max rate using a base of external time of 51.3kS / s.  When you put s and 9234 9233 s in the same spot, DAQmx chooses the fastest time base module (in the 9234 in this case) and he shares with the other modules.  This has the effect of executing your 9233 s to 51.2 kech / s and is located in the module specifications.

    I don't know why you do not want to run run the 9233 s 50kS/s, but if you wanted to you could put them in a separate task without the 9234 and they would use their internal time base to run 50kS/s.

    The other option is to define the basic source of time clock sample and the rate to a base time of one of the 9233 s.  If all the modules have been in the same spot, your 9234 would go then to 50kS/s as well.

    Processor, Yes with a lot of difficulties and costs. Video card, no. It is soldered to the motherboard, so there is no upgrade path that you can follow. There is an available plus motherboard, but if you buy a motherboard and processor and pay for the replacements work it will cost just as much or more the laptop he really wants to.
