Restrictions on the IP VPN peer

Hi all

I hope that someone can help you.

I'm trying to restrict my ASA to meet the demands of the handshake any IP address outside the specified remote peer - I don't have a VPN between the HO and DC. So far I have removed the encryption card WATCH 65535 ipsec-isakmp dynamic SYSTEM_DEFAULT_CRYPTO_MAP I thought I would have responded to any request VPN. I also disabled the SSL VPN for good measure.

I have installed the certificates that I tried to get the rsa - sig, which was a failure - if you have a Watchguard on the other end originally do not try!

The ike-scan output that runs from an address different from the peer:

[email protected] / * /: ~ $ sudo ike-scan - v - M - trans = 5, 1, 2, 5 - id = test

*. *. *. * - showbackoff

Thanks in advance.

Hey Damo,

Assuming that you don't need to IKE to listen to the world, but only to specific counterparts, you can possibly use the access map command option, for example as follows:

test from the list of access permit udp host 10.48.67.145 interface outside isakmp eq

extended access list test deny udp any any eq isakmp

extended list permits all ip one access test

Access-group test in interface out-of-control plan

This will prevent other hosts to reach the IKE process:

% 4 ASA-106023: Deny udp src outside:10.48.67.144/500 dst identity:10.48.67.76/500 by access-group 'test' [0xe4b28725, 0 x 0]

You can learn more about this option on the following links:

  • Validation of the IOS VPN peer identity IP with NAT - T

    I just lost a lot of time to understand this behavior of the IOS. My conclusion reached: If you work with the good old peer identity address validation in profiles ISAKMP and the peer you are talking about is located behind a NAT, you must use the private IP address of the peer in the command "adapter address of the identity". I thought that NAT - T takes care of the translation in all sections of required configuration, but here especially, seems not so much. The interesting thing is that for all other orders, you must use the public IP address.

    See the following example (showing only the relevant articles with statements by peer inside):

    door-key crypto OUR_KEYRING

    key pre-shared key address 1.2.3.4

    Crypto isakmp PROFILE_NAME profile

    VRF TEST

    key ring OUR_KEYRING

    function identity address 192.168.99.5 255.255.255.255

    OUR_MAP 6 ipsec-isakmp crypto map

    defined peer 1.2.3.4

    the value of PROFILE_NAME isakmp-profile

    Does anyone know if this is normal or if it is a bug? It would be useful and consistent if NAT - T changed the identity of the peer address during the phase 1 negotiation, then we would not deal with peer private addressing within site to site VPN configs. I also think of IP scenarios that overlap that may occur when you work with dealing with private peer.

    See the release of relevant debugging in the attachment, after documenting a failed connection attempt (using the public, NATted IP of the peer in the command 'fit the address of identity') and once a following connection attempt (using the IP private, internal counterpart).

    My router is a C2951 with IOS 15.3 (2) T2. The counterpart is an ASA (version & unknown config so far, but I'm sure that the other engineer did not indicate what it is using a private address in its config, despite my session from behind a NAT router, too).

    Thank you & best regards

    Toni,

    Problem with identity is that it is an encrypted package (in Exchange MM) so cannot be changed in transit, so that a host may not know reliably it is the external IP address (it can make assumptions, but he doesn't know how long it is valid for).

    Also if you "NAT 'd" identity you can't the difference between two devices behind same NAT/PAT on end of answering machine.

    There are some implmentations IKE allowing IKE to identity type and value to specify manually. IOS not among them.

    Yes decouple us identity and peer of the intellectual property, it adds flexability with a few corner cases which may arrise.

    Yet another reason why NAT is evil?

  • Unable to connect to the Cisco VPN you use native client: El Capitan

    I'm unable to connect to the Cisco VPN using native client server Cisco OSX via IPSec. Before the upgrade for connections VPN El Capitan has worked without any problems. VPN uses the shared secret of group. It seems, I get the error "raccoon [2580] ': could not send message vpn_control: Broken pipe ' during the connection."

    When I upgraded to El Capitan, VPN connection has stopped working. I tried to do the following:

    * connect using the old work VPN connection: without success

    Config: Hand [server address, account name],

    AUTH settings [shared secret, the Group name].

    Advanced [mode to use the passive FTP = TRUE]

    errors:

    "raccoon [2580]: could not send message vpn_control: Broken pipe"

    ...

    * Add new VPN connection using L2TP over IPSec: without success

    Config: Hand [server address, account name],

    Authentication settings [user authentication: password, identification of the Machine: Shared Secret].

    Advanced [send all traffic on the VPN = TRUE]

    errsors:

    * Add new connection using Cisco via IPSec VPN: without success

    Advanced [mode to use the passive FTP = TRUE]

    errors:

    "authd [124]: copy_rights: _server_authorize failed.

    "raccoon [2580]: could not send message vpn_control: Broken pipe"

    VPN server is high and does not work and accepts connections, this problem is entirely on the client side.

  • Unable to connect via the Cisco VPN Client

    Hello

    I have configured remote access VPN to ASA and tries to connect via the Cisco VPN Client 5.0

    I am not able to connect and watch the journal on the SAA

    ASA-3-713902: Group = xxxxx, IP = x.x.x.x, withdrawal homologous peer table is placed, no match!

    ASA-4-713903: Group = xxxxx, IP x.x.x.x, error: impossible to rmeove PeerTblEntry

    ASA does not support the K9 i.e. VPN - DES is enabled and VPN-3DES-AES is disabled.

    What could be the reason.

    Concerning

    Hi, I had this same problem, here is the solution:

    When you perform a debug crypto isakmp 255, so you see that the cisco vpn client does not support SHA +, you must use MD5 + AN or sha with 3DES/AES.

    Be careful, this debugging is very talkative, but that's the only way I found to get ITS proposal on debugging.

    Well, change your strategy using MD5 isakmp / OF would do the trick.

  • ASA 5520 8.0 (4) port depending on the ACLs vpn works not

    Hi all

    I have a problem with an ASA (5520 8.0 (4)) for lack of working with a port based acl for remote clients. I have a simple acl from a single line to split traffic, if I allowed the tunnel IP works fine, if I lock it up to TCP 3389 rdp will not work. I don't see anything in the logs and debug output, I did have a problem with a similar configuration (5510 8.0 (4) and I'm at a loss to explain it.)

    Everyone knows about this problem before? I have nat exclusions etc and as I said, the tunnel only works if the acl permits all IP traffic between client and server.

    THX in advance

    Split-tunnel list cannot IP, if you want to restrict which ports are are sent via the tunnel vpn for your clients vpn, you need to use VPN filters under Group Policy:

  • The anyconnect vpn easy vpn Remote communication problem

    Hi team,

    I have a problem of communication of the anyconnect vpn easy vpn Remote I´ll explain better below and see the attachment
    topology:

    (1) VPN Tunnel between branch HQ - That´s OK
    (2) VPN Tunnel between Client AnyConnect to HQ - that s OK

    The idea is that the Anyconnect Client is reaching the local Branch Office network, but has not reached.
    Communication is established just when I begin a session (icmp or rdp) branch to the AnyConnect Client,.
    in this way, the communication is OK, but just for a few minutes.

    Could you help me?

    Hello

    communication works when you send the traffic of easyvpn derivation because it froms the IPSEC SA to pool local subnet and anyconnect HQ. The SA formed only when the branch initiates the connection as it's dynamic peer connection to HQ ASA.

    When there no SA between branch and HQ for this traffic, HQ ASA has no idea on where to send the anyconnect to network traffic.

    I hope this explains the cause.

    Kind regards

    Averroès.

    Route ISP_2 3.3.3.3 255.255.255.255 2.2.2.254

    Establishing the VPN tunnels in both directions when using ISP_1 works very well establshing in both directions of remote access users and several tunnels L2L (only showing a for example).

    On ISP_2

    1. peer device 3.3.3.3 establishes a VPN tunnel, but the return traffic does NOT get back to devices 3.3.3.3 tunnel.

    2. the local firewall does NOT establish a VPN tunnel to 3.3.3.3

    It suggests that the problems lies with this firewall multihomed do not direct traffic properly on back down and VPN tunnel of workbenches (point1) or to trigger a tunnel if there is (point 2).

    Reconfiguration of the VPN tunnel to 3.3.3.3 counterpart to be on the local firewall, all the springs in the life ISP_1! All ideas, there are enough license etc...

    Another way you need is the subnet of destination on VPN_ACL_B to be routed to ISP_2 as well.

    So you must send the address of peers (in your case 3.3.3.3) and the remote subnet (in your destination subnet case VPN_ACL_B) at 2.2.2.254

  • Coming out of the IPSec VPN connection behind Pix535 problem: narrowed down for NAT-Associates

    Hello world

    Previously, I've seen a similar thread and posted my troubles with the outbound VPN connections inside that thread:

    https://supportforums.Cisco.com/message/3688980#3688980

    I had the great help but unfortunatedly my problem is a little different and connection problem.  Here, I summarize once again our configurations:

    hostname pix535 8.0 (4)

    all PC here use IP private such as 10.1.0.0/16 by dynamic NAT, we cannot initiate an OUTBOUND IPSec VPN (for example QuickVPN) at our offices, but the reverse (inbound) is very well (we have IPsec working long server /PP2P). I did a few tests of new yesterday which showed that if the PC a static NAT (mapped to a real public IP), outgoing connection VPN is fine; If the same PC has no static NAT (he hides behind the dynamic NAT firewall), outgoing VPN is a no-go (same IP to the same PC), so roughly, I have narrowed down our connection problem VPN is related to NAT, here are a few commands for NAT of our PIX:

    Results of packet capture are listed here for the same PC for the same traffic to Server VPN brach, the main difference is UDP 4500 (PC with static NAT has good traffic UDP 4500, does not have the same PC with dynamic NAT):

    #1: when the PC uses static NAT, it is good of outgoing VPN:

  • Control the access of the user for the SSL VPN profile.

    I have two ssl vpn profile, can I restricted the user to access only ssl vpn profile, when they get to the page of the ssl vpn service. Each profile to create different types of access, and they will have different client IP address.

    Hello

    Yes, using different ways; one of them is using group-lock, which is a simple check to validate if the Tunnel group or the connection profile as you called it with that sign corresponds to what you have defined under group policy. If the value of Tunnel-Group-Lock (condition true), the VPN remote access session is allowed to install;  otherwise the session is not allowed to be implemented.

    The tunnel-group-lock featurecan be defined as follows:

    • via the group-policy setting locally on ASA
    • via the LDAP attribute
    • via the Radius attribute

  • What is the best vpn for OS 10

    What is the best VPN for my MacBook Pro running Yosemite

    The question is really not much sense.

    A VPN is not something that you install on a computer. It's a service that you connect to, as such, there is no better for a specific type of computer.

    What exactly you need to accomplish with a VPN?

    Usually, a VPN is used to connect to a remote network and use its resources, such as printers and servers, as if you were connected locally to them.

  • Locked out of my iPad on lock due to restrictions of the child screen

    When we use FaceTime we always allow child restraint (disabling screen etc) for our child can also facetime with family, preventing to end the call.

    We just got a call, answered he, restrictions enabled by clicking the home button 3 times.

    the call is completed on the other side, the iPad has jumped into the lockscreen.

    But the restrictions of the child are still on. Outside of the FaceTime app.

    but the lockscreen does not allow me to push the code to turn off the child lock.

    So now I'm locked out of the iPad. all buttons and off screen.

    Anyone an idea how to get back?

    Resolved now power + home until you restart.

    After the reboot, the lock is disabled.

  • Restrictions on the HW HP (small businesses) to license reuse laptop components?

    Restrictions on the HW HP (small businesses) to license reuse laptop components?

    I realize that it is illegal to use a part of the (OEM) software that was distributed with the renovated nw8440 Mobile Pro HP workstation (laptop HP Compaq small business) I bought (HP direct) on a different computer (that software provided with).

    My question concerns well hardware components (HDD, keyboard, memory modules, speakers, mouse, etc.) accompanying.
    Specifically, is it legal for me to use these hardware components on a different computer (that the software provided with), or even to sell it, give it, or Dispose (separately from the HP computer system it is come with)?

    The reason why I ask this is that among the license agreements supplied with the system says something like:

    • The initial user of the product can perform the unique transfer of the product to another end user. ... The transfer may not be an indirect transfer, such as a consignment.

    and I am his retirement that computer (Windows XP) and am not familiar with these license terms.

    I just started to use his hard drive in a desktop computer more old we which hard drive has failed.

    I think that should be OK license-wise, but it made me wonder what restrictions, if any, I might have on other future uses of this type of material.

    Thank you.
