    Hello

    As for your question, you can have more than 1 card crypto on the interface.

    However, you can use the same card encryption for several strategies. You can change the ma-card to vpnmap.
    In this way the two are enabled on the same interface, with one having a higher priority than the other.

    So if a package came from inside, the first crypto ACL interface is checked and then the next and so on. The first match found is chosen for the IPsec negotioation.

  • I need help for the upgrade of my current system.

    I need help for the upgrade of my current system.

    I have SBS 2008 with (Exch 2007, SQL 2005, Sharepoint, backupexec 2010 for sbs) licenses.

    I want to make the larger environment using the following:

    (1) apply Virtualization

    (2) apply to the failover process (clustering)

    "(3) the environment must support adding server terminal server, ERP server, exchange server, domain controller, backup manager.

    Storage 4) that supports Raid (1 and 5)

    UTM excellent 6) that supports (SSL VPN, VPN Global)

    suitable backup solution 7)

    (8) good antivirus for clients

    my questions:

    (1) can you provide me with a good design for this environment

    (2) should I choose what operating system:

    Microsoft datacenter or company

    I know datacenter provide us the unlimited VM but needs per processor license

    so if I have two Grouped servers I want to buy 4 licenses

    and just 4 VMs per company license... to say that we have two servers and maintain 8 vms so wat happened if 1 goes down... How can I migrate the 4 virtual machines on the server failed to another server group... ? should I buy enterprise license?

    (3) if I get the SAN storage for data... How can I save this storage... should I get another SAN?

    (4) how can I upgrade SBS stad single server (windows standrad) without losing the licenses as Exch 2007, SQL 2005, sharepoint.is it a must to buy an edition full std server or there is a way to upgrade (license wise, I mean)?

    (5) what about win2k8 license for VM:

    lets say we have physical that has windows license so that enough to have windows for VM or should I buy windows for VM licenses?

    (6) can I use backExec license for SBS with windows 2008 standard

    (7) who better to virtualization AMD or INTEL

    (8) hyper V or VMware?

    (9) what of Microsoft data protection Manager... is this good?

    (10) what virtual machine manager? What are the benefites keys

    Is availble for IPsec VPN FOS 6.3 support stateful failover

    SAJ

    Hello Saj,

    Unfortunately not... stateful failover replica information such as:

    Table of connection TCP, udp xlate table ports, h.323, PAT port allocation table...

    they replicate data such as:

    user authentication (uauth) table

    Table ISAKMP / IPSEC SA

    ARP table

    Routing information

    Therefore, in the case where the main breaks down, the IPSEC vpn will be reformed for the failover... Meanwhile, the user will not be able to access the applications...

    I hope this helps... all the best... the rate of responses if deemed useful...

  • Need help for optical safety circuit.

    I buy these parts and prototype with real components, but since I multisim, I thought it would be nice to create the circuit and maybe work through issues I can practically.

    I need a circuit that takes 120 VCA, generates 5 VDC and 1.5Vdc power of optical transmitter and receiver.  I actually use a data port because he has great range and is pretty cheap.  Rather than send the binary code well I just send a light stead that is broken or not broken through doors and windows in my house.  Then the receiver sees this as an entry and order a relay.

    I tried several voltage regulators that come with multisim, but I get an error of execution of my circuit.  Really I can't the 120 VAC to power levels necessary for the functioning of the optics.

    Otherwise I might want to run on a system 120Vdc with battery backup, so throw a 120Vdc up to 20 v DC switching power supply - but I have not found a SMP in the library which takes 120 as input and as output 20.

    Basic plan: 120VAC source-> transform to 24Vac-> Full bridge rectifier to ~ 20 v DC-> voltage capacitor filter on the input of two voltage regulators (1 to 5 VDC, 1 to 1.5Vdc) - then circuit since the two power supply of the transmitter and the receiver.

    I just need help for 5V and 1.5V, from there, I know that the real world circuit will work component tests already carried out.  Thanks for reading.

    I didn't Multism so I can't advise you on the compatible models. I ran the model on semiconductors with slight modifications of format on my SPICE simulator based on Berkeley Spice 3f5. I had to change the format of model resistance semiconductors appeal but has not changed any values.

    The output of your power supply circuit 3 (with 5 V, not the 1.5 V regulator regulator) was 4.99995 V.

    There are a few messages about changing templates published for compatibility Multisim woth. You can search those to see if there are any suggestions on what you'll need to fix in the model.

    Thank you

    Hi Jixian, the native client MAC does not work. The IPSEC VPN client is the same as the 5.x Cisco VPN client is not supported on this device.

    Your alternatives are to use PPTP or a 3rd party IPsec client such as ipsecuritas.

  • Need help with Config VPN on ASA5505

    Our client has a seller who needs to establish a VPN tunnel to their own router that sits behind our firewall.

    Concentrator VPN (seller) ASA5505 customer (7.2) <------> <------->3750 Switch <------->VPN router (Vendor)

    Here is the implementation of information:

    ASA outside Interface - 208.64.1x.x4 DG - 208.64.1x.x3

    ASA inside the Interface - 172.20.58.13/30

    3750 switch Interface connected to ASA - DG - 172.20.58.13 and 172.20.58.14/30

    3750 switch Interface connected to router VPN - 172.20.58.21

    The Interface of the VPN router connected to the 3750 - 172.20.58.22/30 DG - 172.20.58.21

    I have also attached a Visio for that and the current configuration of execution of ASA and 3750. We have no access to the router VPN TNS.

    Our responsibility is to everything just to make sure that the tunnel rises.

    You kindly help me with this?

    Here is what I intend to do:

    (1) create a static NAT on the ASA Public Private IP Address of the VPN router

    Public - 208.64.1x.x5 / 28

    Private - 172.20.58.21 / 30

    Will be the ASA automatically ARP for this address or do we I have to configure another interface on the ASA with this public IP address?

    (2) what would the access on the ASA list?

    (3) the customer gave us some config to copy the stuff on the SAA so that they can create the tunnel but I couldn't put these commands in the SAA. How this would apply and which interface?

    Access to firewall: the information below is about access between the VPN router and the

    VPN concentrator. If a firewall/router is present in front of the VPN services must be

    Can someone help me with the commands I need to run it on the ASA? The 5505 running 7.2 code (4).

    Thanks in advance.

    HS

    Your steps are correct, you need to configure static NAT and the list of access to allow access.

    Static NAT would be as follows:

    static (inside, outside) 208.64.1x.x5 172.20.58.21 netmask 255.255.255.255

    You also need a road inside interface-oriented join 172.20.58.21:

    Route inside 172.20.58.21 255.255.255.255 172.20.58.14

    You have already access list on the external interface? If you have, then just add in the existing access list, if you don't have it, and then add the following:

    access list outside-acl permit udp any host 208.64.1x.x5 eq 500

    access list outside-acl permit udp any host 208.64.1x.x5 eq 4500

    access list outside-acl allow esp any host 208.64.1x.x5

    Access-group acl outside in external interface

    If you also have an inside interface access list, you must also allow passing traffic by as follows:

    access-list allow host 172.20.58.21 udp any eq 500

    access-list allow host 172.20.58.21 udp any eq 4500

    access-list allow host esp 172.20.58.21 all

    If you have not had any access inside the interface list, then you don't need to configure it.

    Hope that helps.

  • Need help for reading in parallel on the same interface and writing XNET

    Hello. I need help to configure CAN interface to write and read from the same interface.

    I use NI PXI-8513/2. I use CAN1 as interface.

    My had TO send status messages CAN every 100ms. I have to read in order to return akntoowlege to keep DUT CAN interface happy and not make mistakes.

    So, I want to open Strim Session and readall frames in the loop. At the same time, I need to be able to write in a frame HAD at the time...

    I only need to read one picture at a time too, but since I know the ID, I can pull it from the stream.

    What I'm confusing all is how to put in place the same CAN1 interface to be able to write and read in parallel.

    I think I would get errors that interface is already in use.

    Since I'm new to CAN, I was read and write only when necessary. But, sometimes I was getting errors on my messages. Sometimes I get message, sometimes miss me. But, when I run CAN test criminal as sniffer he sends and written every time. I was told it's because it recognizes all messages.

    I opened to suggestions of how best to implement the interface.

    I guess I can use CAN2 and separator to work around this problem, but I would use an interface if possible.

    Thank you

    Hi Rus,

    The XNET hadrware takes care of most of the low level of detials for you. The reading and writing of the circuits are both connected to the bus at any time. When you write to the hardware it will try to put a frame on the bus at the first opportunity he can. If the frame loses arbitration material re - will attempt to send the frame up is successful. Reception equipment monitor activity on the bus, regardless of what it conveys. The material received will usually throw a framework that was sent by communication equipment, but there is an Echo property pass to circumvent this behavior too.

    Take a look at the example of the expedition: MAY-> NI - XNET-> Sessions-> multiple Sessions Intro-> CAN even exit entry framework Port unique Point.vi. Keep in mind that this example you will need to use a second CAN interface to recognize frames, it transmits. I would recoment against the example CAN output Frame Single Point which would mimic your ECU if you choose a type of cyclic frame running this example.

Maybe you are looking for
