Packet encryption and decryption by IPSEC Tunnel

Hello world

You must confirm if Site A has VPN IPSEC to Site B through Public network.

PCs on site say a package is sent in clear text to the switch, then switch sends to the VPN router.

Router VPN to site A will make encryption and send over a WAN link encrypted.

When the packet reaches a router B Site it will decrypt the packet and send clear text to PC right of the site B?

Thank you

MAhesh

Hello Manu,

Yes, you are right.

Encryption and decryption will perform VPN closing devices.

Best regards

    Hello

If I encrypt also I can able to run and remove the scenario and what ever.please suggest me and so I have can use this concept in my Production.

    Hello

    Encrypt a script/procedure/KM helps protect the valuable code.

    An encrypted script or KM or a procedure cannot be read or modified if it is not decrypted. Orders generated in the newspaper by a scenario Encrypted KM or procedure are unreadable.

    Oracle Data Integrator uses a personal encryption key-based encryption algorithm. This key can be saved in a file and reused to perform encryption or decryption operations.

    P.S:there is impossible to decipher a procedure without the encryption key or encrypted KM. Therefore, it is strongly recommended to keep this key in a safe place. It is also advisable to use a unique key for all developments.

  • Decision on DMVPN and L2L simple IPsec tunnels

    I have a project where I need to make a decision on which solution to implement... environment is as follows...

    • 4 branches.
    • Each branch has 2 subnets; one for DATA and another for VOICE
    • 2 ISPS in each (an Internet access provider and a provider of MPLS)
    • Branch #1 isn't necessarily the HUB office that all database servers and files are there are
    • Branch #2 is actually where the phone equipment
    • Other 2 branches are just branches speaks (may not need never DATA interconnectivy, but they do need interconnection VOICE when they call since we spoke directly to the other)
    • MPLS is currently used for telephone traffic.
    • ISP provider link is used for site to site tunnels that traverse the internet, and it is the primary path for DATA. Means that all branch DATA subnets use the tunnels from site to site as main road to join the #1 branch where all files and databases are located.
    • I'd like to have redundancy in case the network MPLS down for all traffic VOICE switch to L2L tunnels.

    My #1 Option

    Because it isn't really a star to the need, I don't really know if I want to apply DMVPN, although I read great things about it. In addition, another reason, I would have perhaps against DMVPN is the 'delay' involved, at least during initialization, communications having spoke-to-spoke. There is always a broken package when a department wants to initiate communication with one another.

    My #2 Option

    My other choice is just deploy L2L IPSec tunnels between all 4 branches. It's certainly much easier to install than DMVPN although DMVPN can without routing protocols that I think I'll need. But with these Plains L2L IPSec tunnels, I can also add the GRE tunnels and the routing of traffic protocols it as well as all multicast traffic. In addition, I can easily install simple IP SLA that will keep all tunnels upwards forever.

    Can someone please help to choose one over the other is? or if I'm just okay with the realization of the #2 option

    Thanks in advance

    Hi ciscobigcat

    Yes, OSPF will send periodic packets 'Hello' and they will maintain the tunnels at all times.

    The numbers that you see (143 and 1001) are the "cost" of the track, so OSPF (Simplified) will calculate what different paths there are to a destination and assign each of them a 'cost' (by assigning a cost to each segment of the path, for example GigabitEthernet is "lower cost" Fastethernet and then adding the costs of all segments).

    Then it will take the path to the lowest cost (143 in your case, in normal operation) and insert this in the routing table.

    So since traffic is already going the right way, I don't know if you still need any tweaking? Personally, I would not add a second routing protocol because, generally, makes things more complicated.

    QoS, it is important to use "prior qos rank".

    See for example

    http://www.Cisco.com/en/us/docs/solutions/Enterprise/WAN_and_MAN/QoS_SRND/IPSecQoS.html

    Oracle knows nothing about your data is encrypted. So like all other columns, the column must be defined with a length that will contain the largest value that it must take. Redefine the column to make it longer.

    Have you considered using the Oracle Transparent data encryption?

    < cfoutput > #txtuserid1 # < / cfoutput >

    Thank you!!!

    In the encryption

    Encrypt (txtuserid, "#txtuserid #")

    1st parameter is the string to encrypt.

    2Md parameter is key or seed used to encrypt the string.

    In decription

    encrypted_string String or a variable that contains a. String to decipher
    seeds Required string. The 32-bit key that was used to encrypt the string.

    main.cfm (test only)


    #URLEncodedFormat(Encrypt(txtuserid, "> ' > Click me.

    Here the key to encryption is 'txtuserid' (123)

    for decription same key must be used for encryption

    Main2.cfm

    #txtuserid1 #.

    Here the value of txtuserid IE the 2nd parameter is the decryption key that wasn't the same key you used to 4encryption u have to also use the same key for decryption. If you change

    Main2.cfm

    #txtuserid1 #.

    you will get the response as 123.

    Please try the example below... Then, you'll get the IDEA

    main.cfm (test only)



    #URLEncodedFormat(Encrypt(txtuserid, "> ' > Click me.

    Main2.cfm

  • Resolution in real-time for IPSec Tunnel peer

    Hello

    There is a document on Cisco's Web site

    http://www.Cisco.com/en/us/docs/iOS/12_3t/12_3t4/feature/guide/gtrlres.html

    explaining that when setting up a card encryption static and peer instead of the IP address peer, we can specify following domain COMPLETE with "dynamic" command name I tried this option and no luck. My VPN end point (routers 2611XM and 831) solve another name with a DNS server, but when it starts to lap crypto maps to interfaces I get the following error message:

    ISAKMP: reminder: no SA is for 0.0.0.0/0.0.0.0 [vrf 0]

    Virtually no SAs are set up and malfunctioning coming IPSec tunnel.

    Everyone tried and had the same problem? I would appreciate your help on this.

    Thank you

    Remi

    What authentication method you use? If you use "pre-shared" you can't always use not "cry isa key... name...". "even if the DNS resolves this IP. It is a feature of the IKE Messrs. use so, CERT.

  • NAT on IPSEC tunnel on cisco router

    Hello.

    I have a central router works as a Hup with two talks about routers, but rays routers has the same encryption domain network (the same local Network Segment), I need to do a nat on one of VPN tunnels to avoid conflicts in the concentrator, router. Can anyone help me?.

    Sent by Cisco Support technique iPad App

    NAT is performed before the encryption and decryption, so you should be able to configure your NAT as you please.

    Example:

  • Can I use private as Source IPs from a remote network IP addresses while building the IPSec tunnel?

    Can I use private as Source IPs from a remote network IP addresses while building the IPSec tunnel? If not why? If so, how?

    Your explanation is much appreciated.

    Hi Deepak,

    In such a situation, you usually NAT traffic that goes to the internet, but exempt traffic that goes through the VPN, because it will be wrapped in packages with public IP (tunnel) addresses. You can use the same IP address on your interface in the face of internet for the NAT/PAT and source of IPSEC Tunnel.

  • IPSec tunnel and NetFlow packets

    I have a router 1841 IPSec running with an ASA. F0/0 is the source interface. I also set up NetFlow, which must be sent through the IPSec tunnel to the parser. The acl setting the IPSec interesting traffic covers addresses, source and destination of NetFlow. But NetFlow Traffic is not captured by the tunnel. When I ping the destination router, icmp traffic is picked up and goes through the tunnel. Are there ways to force NetFlow traffic to go to the tunnel?

    Thank you.

    Y at - it a route to the destination address of netflow? I have noted problems with traffic heading towards a destination that was not in the routing table is not made down a VPN.
