IPSEC encryption package is encrypted

IPSec will encrypt a package that is already encrypted? Don't care if IPsec package is already encrypted, or just run the encryption on the pack and decipher it without care if its encrypted already?

Advertisement

IPSec do not care if the package is already encrypted. A case is ipsec in ipsec tunneling, where you would be tunnel log ipsec from your pc to a session ipsec server on a lan-to-lan (or site to site).

The only thing that IPSec will rely on when he decided to protect/encrypt a package is if the source and dest are an interesting access list. So if the acl crypto says to allow ip net1 to net2 occurs, ipsec protection even if a previous router apply ipsec between on net1 host1 and host2 on net2.

  • Proposal of IPsec encryption

    Dear Cisco

    I would like to know if I only use IKEV2 VPN site-to-site with Cisco 5505 connection peripheral to connect a few site.  What method of encryption is best to choose with more fast and stable IPsec encryption proposal

    AES256, AES192, AES, 3DES, AND? What is the best site to site IKEV2 VPN tunnel?

    Best regards

    Alan

    AES is faster than the algorithm, so I would exclude both OF or 3DES.

    If you want only the safest of the AES, pls use AES256

  • On DMVPNs selective IPSec encryption

    Hello

    I have a DMVPN with two rays on a MPLS-L3-IPVPN network. IPSec over GRE profiles using crypto. Works very well. Now, he only need to encrypt all traffic except EF DSCP. Tried with the help of ACB defining IP-Next Hop for EF-packages and just normal dug routing for all other types of traffic.

    My question is, I know cryptographic cards that use ACLs can selectively encrypt traffic through the IPSec/GRE tunnels. Cryptographic profiles don't seem to have this feature. Is there another way to do this?

    With DMVPN, no.  You will need to return to the use of just cryptographic cards, only using access lists to control what is and is not encrypted.

    If the "EF" traffic was dedicated VoIP subnets so you would have more options, you can choose everything just don't not to route these subnets above the Tunnel.

  • IPSEC encryption beyond the borders of the country

    A question about creating encrypted VPN tunnels in the United States to the Ireland and/or the United Kingdom:

    Are the limits or restrictions on encrypt an IPSEC Tunnel with regard to connections sent outside the United States?  My brain has a few blurred memories of "export restrictions".

    You can use crypto enough everywhere, but you can use crypto "fort" in us of the countries 'limited '.  In some cases, there is a limit of flow crypto (85 Mb/s of memory).

    The United Kingdom and the Ireland wouldn't the American controlled export destinations for strong cryptography, so you won't have any problems.

    Note that most of the Cisco routers with base licenses comply with the speed limit, and you must purchase the HSEC license to activate the additional throughput.

  • Encryption of Gigabit

    Hi all

    I'm looking for a Cisco router (preferably) for a design I have write

    at this rate.

    Any ideas/experience? It is a MPLS VPN connection and we hear

    using DMVPN with IPSEC for encryption of the EC - ec. That's a financial House and headquarters

    Thank you all

    Stephen,

    I'm not sure of current sheets, perhaps better to do a ping of a Cisco self?

    Possible solution cat6k + VPN SPA or ASR1k (not sure that sheets are saying about this last tho)

    Marcin

    Edit: ASA will not manage DMVPN so I did not mention 5580.

    Find the link, I had in mind

    http://www.Cisco.com/en/us/prod/collateral/iosswrel/ps6537/ps6586/ps6635/ps7180/prod_brochure09186a00801f0a72.html

    With regard to the experience...

    If you don't want one not far from the step configuration guide, VPNSPA is very correct.

    ASR1k has a good potential, but it's still new, a great team so internally.

  • Microsoft l2tp IPSec VPN site to site ASA on top

    I have a specialized applications casino that requires end-to-end encryption. I'm under the stack of Microsoft IPSec l2tp between my XP machine and my Windows 2003 server on the LAN. Can I use the same type of protocol stack Microsoft l2tp IPSec between my XP machine and the Windows Server 2003 a branch on the SAA to site to site ASA VPN tunnel? The VPN site-to site ASA is a type of key Preshare IPSec VPN tunnelle traffic between our head office and a branch in distance.

    In other words, the ASA site-to-site IPSec VPN will allow Microsoft l2tp through IPSec encrypted traffic? My ACL tunnel would allow full IP access between site. Something like:

    name 192.168.100.0 TexasSubnet

    name 192.168.200.0 RenoSubnet

    IP TexasSubnet 255.255.255.0 RenoSubnet 255.255.255.0 allow Access-list extended nat_zero

    Hello

    Yes, the L2TP can be encapsulated in IPSEC as all other traffic.

    However, make sure that no NAT is performed on each end. L2TP is a default header protection which will see NAT as a falsification of package and reject it.

    Thoughts?

    Thank you

    You cannot use the mode of transport in this situation. You need two-heads IP here: one for end tp (1.1.1.1 to 2.2.2.2) communication and one for transport of IPsec (12.12.12.1 to 12.12.12.2). This is the reason that your router automatically in tunnel mode.

  • VPN IPSEC RV220w problem

    Hello, I hope someone can help with my problem.

    I have a RV220w in the office, I set it for ipsec vpn connections. Behind the router, there is a NAS for file storage.

    My setup as follows:

    RV220w 192.168.1.1 with dyndns, configured for ipsec vpn with default Client strategies.

    Remote location (my laptop) local IP: 192.168.3.2

    Remote site VPN IP (given by ShrewVPN): 192.168.30.5

    I managed to connect to the router at home with ShrewVPN and I can ping each client connected to RV220w.

    The problem is that I can't connect to the web interface of the router or the NAS web interface or any other web page intranet (the browser gives no error, but continues to load without displaying the web page). Even if I can access the web pages of my laptop.

    In addition, in windows Explorer when I log into the NAS, although I can go through the files, I can't copy the files from my laptop on the NAS and vice versa, I still get timeout error (I checked the permissions on the NAS and also I managed to copy a txt file small 1 KB) (, but no luck with large files).

    I also tried with QuickVPN client, but I got the same results.

    When I connect with pptp windows everything works like a charm.

    My laptop has windows 7 64 bit.

    If you need other configuration details, please advice.

    Thank you

    Hi Spyros, one of the differences between IPsec and PPTP is that IPsec requires the client that connects to use another LAN IP address, when you connect. Unlike PPTP, it is assigned by the router.

    Another difference is that the requirement of bandwidth is much higher for IPsec connections.

    I don't think it's a problem of IP subnet as you are able view readers to all least, then it means that the unit can accept connections from different subnets. But it is possible, it may be a problem of download speed. QVPN needs Mbit upload environ.5 to have an activity and a reliable and quality connection.

    Another problem may be a matter of downtime with IPsec encryption. The RV220W has a non routable WAN address. This suggests to me that you have another router upstream. Time to answer through the IPsec tunnel can be volatile because of the translation through multiple jumps.

    access-list 100 permit gre 203.115.12.1 host 203.115.34.4

    I understand the purpose of the ACL above regarding the test configuration that I posted here.

    Let me explain.

    LAN - router - WAN - router - LAN

    Communication between the two LANs can be on a GRE tunnel to an IPsec tunnel or IPsec/GRE tunnel.

    If you simply want to communicate between them unicast IP traffic, IPsec is recommended because it will encrypt the traffic.

    If you need non-unicast or non - IP traffic through, then you can create a GRE tunnel.

    If you want IPsec encryption for the GRE tunnel and then configure IPsec/GRE.

    The ACL you mention will not work because the GRE traffic is only between tunnel endpoints.

    The traffic that flows between local networks is the IP (not the GRE traffic) traffic where a permit GRE ACL will not work.

    It will be useful.

    Federico.

  • VPN IPSec S2S problems

    Hello

    I have a headquarters and a remote site and I want to get a VPN site-to site between the two. I have the following Setup on each router. 'Show encryption session' says that the VPN is in the IDLE-UP condition (and my somewhat limited understanding of virtual private networks, this means that the phase 1 of IKE is complete and waiting for phase 2) When you run a "debug crypto ipsec" on the remote site, I get "no ip crypto card is for addresses local 100.x.x.x" and the VPN remains to IDLE-UP. The ACL on the external interface allows the IP of the remote site. I have CBAC running on the external interface of both routers and ACL permits all traffic between the addresses 100.x.x.x and 200.x.x.x. Could someone help me with the config? I have to do something wrong somewhere.

    Thank you!

    Hi Shaun,

    Some comments...

    The QM_IDLE means that the phase 1 is established. (sh cry isa his)

    You should see with "sh cry ips its" that he has put SAs in place for IPsec encryption/decryption of traffic for the phase 2.

    The ACL for VPN (the crypto ACL) should be one mirror of the other (you have "all" on one side and two statements by the other peer network.

    You do NAT, therefore, there should be a 'workaround NAT rule' VPN traffic (to remove the IPsec NAT traffic).

    This should be it.

    Federico.

    I am a site configuration to site IPSec VPN using a PIX515E to site A and ASA5520 to Site B.

    I have attached the lab diagram. Consider PIX and ASA are in default configuration, which means that nothing is configured on both devices.

    According to the scheme

    ASA5520

    External interface is the level of security 11.11.10.1/248 0

    The inside interface is 172.16.9.2/24 security level 100

    Default route is 0.0.0.0 0.0.0.0 11.11.10.2 1

    PIX515E

    External interface is the level of security 123.123.10.2/248 0

    The inside interface is 172.16.10.1/24 security level 100

    Default route is 0.0.0.0 0.0.0.0 123.123.10.1 1

    Could someone tell me how to set up this configuration? I tried but didn't workout. Here is the IKE protocol I have used.

    IKE information:

    IKE Encrytion OF

    MD5 authentication method

    Diffie Helman Group 2

    Failure to life

    IPSEC information:

    IPsec encryption OF

    MD5 authentication method

    Failure to life

    Please enter the following command

    on asa

    Sysopt connection permit VPN

    on pix not sure of the syntax, I think it is

    Permitted connection ipsec sysopt

    What we are trying to do here is basically allowing vpn opening ports

    Alternatively you can open udp 500 and esp (or port ip 50) out to in on the two firewalls

  • ASA5505: Configure the ASA for IPSec and SSL VPN?

    Hello-

    I currently have my 5505 for SSL AnyConnect VPN connections Setup.  Is it possible to set up also the 5505 for IPSec VPN connections?

    So, basically my ASA will be able to perform SSL and IPSec VPN tunnels, at the same time.

    Thank you!

    Kim,

    Yes, you can configure your ASA to support the AnyConnect VPN IPSec connections and at the same time.  In short, for the configuration of IPSec, you should configure at least a strategy ISAKMP, a set of IPSEC, encryption, tunnel group card processing and associated group policy.

  • Pix IPSec support

    Hello

    I'm trying to set up a tunnel to PIX-501 6.3 version. It's an old device that needs to be replaced soon, but unfortunately we have a tunnel now...

    I used this document as reference (6211): http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080094761.shtml

    The remote end is a sonicwall.

    The problem seems to be that the pix never sees interesting traffic for the tunnel and never tries to establish a connection. I activated the ipsec encryption and debugs isakmp crypto, but no data is never displayed, even when you try to access a device on the remote side of the tunnel!

    Someone tried to implement this feature with some tunnels in the past, but never succeeded, so I think it can stay commands in the running-config causing problems...

    I'm grilled at this stage, so any help would be greatly appreciated. I will provide all necessary information as needed.

    Thank you very much.

    The issue is your inside interface/subnet has been configured as a 16 network and it duplicates the remote network.

    The inside interface: 172.21.25.254 (mask: 255.255.0.0), and network remote 172.21.19.0/24 also falls under the same subnet.

    Instead of routing the packet, inside host will try to proxyarp for the destination that they think they are in the same subnet, so does not.

    Try changing the inside interface with 24 subnet if you want to keep the same IP address and also change the mask of 24 inside your host.

    Otherwise, you need to configure NATing to a completely different subnet to the remote 172.21.19.0/24.
