How to change address on ASA 5520 VPN peer

Environment:

7.2 (1) running ASA 5520

IPSEC VPN L2L established by using wizard.

Change the IP address of the remote peer. Using ASDM, I can't change the name of the Tunnel Group (which is currently the address peer). I may change the address peer in the IPSec rule, but is that all that is necessary?

I have to add a new group of tunnel using the new address of peers for the name? If yes how it is related to other objects that are required for a VPN?

When you create a VPN using the wizard, it creates several objects that are difficult to track when changes are required. Is it better to remove all current VPN objects and create a new configuration using the wizard again?

Is it's better to make the changes using the CLI? What lines must be changed for peer address when using the commands?

Thanks in advance for any help!

I may change the address peer in the IPSec rule, but is that all that is necessary?

-No, tunnel group name must match the peer address.

I have to add a new group of tunnel using the new address of peers for the name?

-Yes.

Is it's better to make the changes using the CLI?

-I recommend it, but if you don't know you have no choice.

Add new tunnel-group with group as new name address peer, same key etc. Add a new address peer settings under rule edit ipsec peer. Then you should be able to remove the old tunnel group. Hope this helps you, been a while since I made this way.

  • ASA 5520 VPN licenses

    Community support,

    I want to run this question by you guys to avoid the sales of our partner CISCO and similar pitch more to the best solution that would give us what we want.

    We currently have a VPN from CISCO 3020 hub to terminate the Lan-to-Lan tunnels and have our mobile workers to connect through the client VPN CISCO (300 users-employees and contractors).

    Given that this device is coming to an end of LIFE this year, we bought a CISCO 5520 (here is the current licenses in this topic)

    Licensing seems quite complicated, so here's my question:

    -What VPN do you recommend for our users and entrepreneurs? I understand that the CISCO VPN client does not work with ASA 5500 Series devices

    Is there a license needed to deploy a VPN solution for our remote users(employees/contractors)?

    Thank you

    John

    Your understanding that the Cisco VPN client does not work with ASA is wrong. Maybe it's the version of Cisco VPN client that you use currently does not work with ASA. But these (and so not very new indeed) versions of VPN client work with the ASA. I installed for several clients who use the traditional IPSec VPN client with ASA ASAs and they work well.

    You are right that the granting of licenses for the SAA is complicated. Your tunnels IPSec VPN site-to-site will work on the SAA and pose much challenge in terms of licenses. But there are problems and alternative solutions to consider for remote access VPN clients. At this point, there are two major variants: you can use the classic IPSec VPN client or you can use the new AnyConnect client. From a licensing perspective there is a Hugh difference between them. It is not special license that applies to the traditional IPSec client and they are just against your license for peers Total VPN (for which you have 750 in your license). For the AnyConect there is a condition of licence. There is a premium for AnyConnect license and there are licensed AnyConnect Essentials. The Essentials license price is much lower than the premium license, but Essentials does not all the features that made the premium.

    In the immediate future, that it would sound like an easy question to answer, use the traditional IPSec VPN client for which theere is not a special permit and it is what you are used to. However Cisco has announced the dates of end of sale and end of Support for the traditional VPN client. If at some point you will need to use the AnyConnect client. I would say that if you make the change of the ASA that it might be a good choice to also adopt the AnyConnect client.

  • ASA 5520 - VPN users have no internet.

    Hello

    We just migrated a Pix 515 and an ASA 5520 VPN concentrator.  The firewall part works fine, but we have some problem with our remote VPN.

    Everything inside network is accessible when you use VPN remote but there is no access to our perimeter network or the internet.  I don't know there's only something simple you need that I'm missing, and hoping someone can shed some light on what is needed to allow the VPN tunnel back outdoors and in our DMZ.

    The ASA is running 8.2 (2) 9 and ASDM 6.2 (1).

    See you soon,.

    Rob

    From the 172.16.68.0/24 you can PING 10.10.10.1 correct?

    The 10.10.10.0/24 you can PING 172.16.68.1 correct?

    I'm having a hard time find now how this tunnel is up since you have PFS
    activated on the SAA, but not on the PIX.

    Hello

    Howmany vpn group is supported on asa 5520 with configuraion vpn remote access.

    Concerning

    1 if nat-control is disabled and you do not have any other order NAT in your config file, you do not have it. Try to remove the existing "NAT 0" command and "clear xlate."

    2. you must ensure that your network inside know they can go by ASA to access remote vpn client IP. You have any device layer 3 behind the ASA that does the routing. If so, please verify that this is the routing table.

  • ASA 5520 - VPN using LDAP access control

    I'm setting up an ASA 5520 for VPN access.  Authorization & authentication using an LDAP server.  I have successfully configured tunnel, and I can access internal resources.  What I want to do now is to limit access to a specific ad group membership.  In the absence of this belonging to a group, a user cannot access the VPN.

    My VPN client software testing is Cisco Systems VPN Client 5.0.05.0290 Version.  The Group authentication is configured in a connection entry that identifies the Group of Tunnel. I think I wrote that correctly.

    The Version of the software on the SAA is 8.3 (1).

    My current challenge is getting the VPN to stop letting each request for access through little matter belonging to a group.  I found the thread below to be significantly useful, but there is obviously something which is not entirely mesh with my situation.

  • Routing with Cisco ASA 5520 VPN

    I have installed IPsec vpn remote users in the Cisco ASA 5520 using RADIUS in my main network. Works very well. I have a site to my Cisco ASA5520 tunnels going to other sites, some of the tunnels have Cisco ASA and some have SonicWalls. I wish that my users VPN remote IPSec to be able to navigate in these tunnels is a site to access remote subnets attached to these tunnels. Do I need to use a combination of routing and the ACL? Or can I just use ACL only? Or just use routing only?

    Thank you

    Carlos

    Hello

    The key to set up here is the two ACL of VPN L2L end points that determine the 'interesting' traffic to connect VPN L2L. You will also need to confirm that the connection of the VPN Client is configured so that traffic to the remote sites have sent to the connection of the VPN client. There are also other things that you should check on your ASA plant

    Here most of the things you usually have to confirm

    • Set up 'permit same-security-traffic intra-interface' if it is already present in your configuration

      • This setting will allow connections to form between the hosts that are connected to the same interface on the ASA. In this case, applies because the VPN client users are connected to the interface 'outside' of the ASA and also remote sites are connected to the ASA to "external". If the traffic between the remote VPN Client and VPN L2L sites will be to enter and exit the same interface
    • You will need to check how the customer if configured VPN connection. Split or full Tunnel tunnel
      • If the connection of the VPN Client is configured as Split Tunnel then you need to add all the networks from the remote to the Split Tunnel, so that the connections between the VPN Client is transmitted to the ASA and from there connections VPN L2L
      • If the connection of the VPN Client is configured as full Tunnel, then there no problem that all traffic is transferred to the Client VPN connection all its assets
    • Define the VPN pool in the ACL of VPN L2L
      • You should make sure that the pool network VPN Client is defined in the ACL that define 'interesting' traffic to connect VPN L2L. So, you need to add the pool VPN VPN L2L configurations on the sites of Central America and remote control
    • Configure NAT0 / NAT exempt for remote VPN Client to L2L VPN Site traffic at both ends of the VPN L2L
      • You must ensure that the NAT0 / exempt NAT rules exist for the VPN Client for Remote Site traffic. This will have to be configured on the SAA "outside" interface. Format of configuration varies naturally a bit on the ASA Central his software level.

    These should be the most common things to set up and confirm for traffic to flow between the VPN Client and Remote Sites

    Hope this helps please rate if yes or ask more if necessary.

  • 1841. ASA 5520 VPN

    I set up a VPN site-to site between a Cisco ISR 1841 and a Cisco ASA 5520, everything seems to work but I have a few questions.

    1. I must explicitly authorize all VPN traffic in the ACL on the external interface of the 1841, y at - it an equivalent of router "vpn sysopt connection permit?

    2. Although the VPN rises and pass traffic, I have the opportunity to see what follows?

    * 14:11:52.883 22 June: % CRYPTO-6-IKMP_MODE_FAILURE: fast processing mode has failed with the peer 1.1.1.1

    You can share the outputs full? Both sides at the same time?

    Bottom line, I don't think it's normal in IOS 12.4 mainline unless packages are leaking clear ;/

  • Need help - ASA 5520 VPN issues

    Trying to simulate our in-lab recovery facility. I have 2 ASA 5520 who have a site - tunnel site between them.

    That works fine

    But I also have a requirement for remote access in one of the ASA, which formerly connected needs to route through

    the site - tunnel site to another server on the other side.

    So far the Remoting piece connects very well, I can access all networks connected locally but I can't seem to get the traffic

    to move through the site - site of the tunnel on the other side.

    Is this feasible? If so, if there are suggestions that would be appreciated.

    See you soon

    Dave

    The command is not applied to a specific interface.

    The command activate the feature on the ASA to receive traffic from VPN clients on the external interface and send him outside through the same apart from the interface through the tunnel L2L (and vice versa).

  • How to change an existing in ASDM VPN tunnel?

    I currently have a VPN tunnel together upwards, but to change some of the configurations as making ikev2, replacing the SHA512 hash and change it in the DH group 14. I intend to do this in ASDM. I already created a group of tunnel ikev2 that I put the tunnel and created a Card Crypto that is configured with the right proposal ikev2 IPSec and Diffie-Hellman group. All other configurations such as the IP of Peer address and subnets configured and I'll work with the engineers at the other end of the tunnel to ensure that configurations are, I want to just make sure I'm not missing anything. Someone at - he never comes to change the configuration of an existing ASDM so tunnel, and it worked correctly? Here are the steps that I have will be taken as well as those I've already mentioned:

    -Edit the connection profile so that the name of group policy use the correct tunnel that was created for ikev2

    -Enter the pre-shared key local and remote pre-shared key ikev2 tab

    -Change the IKE Policy so that it uses the ikev2 policy that was created to use SHA512

    -Modify the IPSEC proposal so that it uses AES256-SHA512

    -THE CRYPTO MAP IS ALREADY CREATED

    -Change the secret of transfer perfect in group 14

    Hello

    Let me go through your questions to clarify this double:

    1. If I have a Crypto map applied to my external interface with a proposal of IPSec of ikev1 can I just add a proposal ikev2 in this Crypto map as well?

    If you have a card encryption applied to different peers outside and 3 with different order number, you will need to replace the proposal for the peer using IKEv2: IKEv2 IKEv1, the others must continue to use their IKEv1 IPSec proposal.

    2. so can I add an ikev2 with AES256 SHA512 hash proposal to my 123.123.123.456 tunnel group and continue to have all three tunnel groups always pass traffic? What happens if I add the proposal ikev2, but REMOVE the ikev1 this group of tunnel proposal because I don't want this group of tunnel use one other than AES256-SHA512 hash?

    123.123.123.456 - ikev2 - AES256-SHA512

    I would like to expand this a little more, if her counterpart 123.123.123.456, must use IKEv2, you need to declare the IKEv2 in the tunnel group and add the relevant "Local and remote PSK"--> is for phase 1, and this means that it will use the IKEv2 defined policy before, and IPSec IKEv2 proposal is on phase 2, where the encryption card is you will need to replace the IKEv1 and use IPSec IKEv2 proposal. That way it will use for the phase 1 of the policy of IKEv2, that you set and defined transformation IKEv2, by making this change make sure that both sides are mirrored with IKEv2 and IPSec policy projects, as well as the tunnel will remain and will come with the new proposals.

    This custom affect no matter what another tunnel, as long as you change the settings to the correct tunnel group and do not delete all the proposals, simply remove the profile connection, those employees.

    3. you know what I mean? All groups of three tunnels on that off interface use different cryptographic cards, with only two of the three using ikev1 as a proposal of IPSec. Which will work?

    You can only have one card encryption applied by interface, and 3 tunnels using different sequence number with the same crypto map name, you cannot 2 tunnels on the same card encryption using IKEV1, and always in the same encryption card have the third tunnel using IKEv2 (different transformation defined using IKEv2). This custom cause no problem. 

    4. what Group Policy DfltGrpPolicy? Currently use all my groups of tunnel, but it is configured for ikev1. I'm not really sure what role is in everything it can so I simply add ikev2?

    Default group policy is added by default to all your groups of tunnel (connection profile), whenever create you one default group policy is inherited him by default, you can change to group policy that you can create, group policy is a set of attributes that will be used to define something or limit , for example, for a site, you can configure a VPN filter (filters the traffic that goes through the tunnel), now back to your topic, you define the protocols that will be negotiated as for an L2L IKEv1 or IKEv2, Anyconnect SSL or IKEv2, on default group policy, and so on, it is therefore important that you add the IKEv2 , so trading will be permitted, or both to create a new group policy and add the IKEv2 Protocol; and in the tunnel group, add the group policy relevant, that you just created.

    I hope that this is precisely, keep me posted!

    Please go to the note, and mark it as correct this post and the previous that it helped you!

  • How to change address billing from one country to another

    I moved from the United Kingdom to South Africa and my current credit card is linked to my new address here. However I can't update my billing information, because the field where I enter my zip code does not accept the format of my current zip code (which is different from my old)

    The country of your payment address, the country on your Adobe account and the store you purchase of should be the same.

  • ASA 5520 VPN

    Hello

    Ask for help if it is possible to have both SSL & ipsec site to site vpn configured on a 5520. If so, would there be no degradation of performance or any limitation of no.. users are allowed.

    Any other things I need to know in this respect.

    Appreciate your help,

    Thank you.

    Yes, you can have the SSL VPN, IPSec Site to site, but also remote access IPSec VPN configured and running simultaneously.

    Here's what ASA5520 can support:

    -IPSec 750 (Inc. VPN Site-to-Site and remote access)

    -750 SSL VPN

    http://www.Cisco.com/en/us/products/ps6120/prod_models_comparison.html

    Please note that for SSL VPN, it only comes with license 2 by default, and you must purchase the SSL license if you want to run more than 2 SSL VPN sessions simultaneously.

    Hope that helps.

  • ISPS double and two redundant ASA 5520 VPN tunnels

    Hi all

    I have a requirement that looks like this:

    -with two ISPs (of course public IP of different subnets), I have two firewalls that we have to do 2 l2l VPN tunnels.

    Virtual private networks will be redundant to each other and in the case where one of the links is congested, traffic should pass through the other tunnel.

    Did someone do something like that?

    Thank you

    Vlad

    Hi Vlad,

    To have redundant connections, I suggest the following link:

    ASA/PIX 7.x: example of redundant Configuration or backup ISP links

    To find out when the link is congested? I don't think it could be possible at all on the SAA, with a UDP IP SLA jitter, but I think that it is supported only on IOS routers.

    Analysis of IP Service levels using the UDP IP SLA jitter operation

    Thank you.

  • How to change address MAC of Console of Service?

    Our network department wants the MAC addresses to create DHCP reservations for all systems with a fixed IP address.

    We have provided all service consoles virtual MAC addresses on our ESX 3.5 U4 machines. This method works.

    After reinstalled an ESX after a failure of the drive, our MAC service console has changed. I am looking for a way to configure the MAC address of the former esx Server installation.

    Is it possible somehow?

    Edit/etc/sysconfig/network-scripts/ifcfg-vswif0 and restart the network.
