• Anyconnect Ikev2 uses aggressive Mode

  Hello world

  I'm trying to fix the IKE Aggressive mode with vulnerabilities PSK on our Cisco ASA that runs old IPsec and Ikev2 Anyconnect VPN.

  When I run the command

  Crypto isakmp HS her

  User using IPSEC VPN

  IKEv1 SAs:

  HIS active: 25
  Generate a new key SA: 0 (a tunnel report Active 1 and 1 to generate a new key during the generate a new key)
  Total SA IKE: 25

  1 peer IKE: 63.226.x.x
  Type: user role: answering machine
  Generate a new key: no State: AM_ACTIVE

  Then, he tells me that this VPN client is using aggressive mode right?

  Need to know anyconnect ikev2 does not share any key of share pre then why the number of line 17 shows AM (aggressive mode)?

  The ikev2 Protocol has nothing to do with the aggressive mode or main at all.

  If you do a 'sh crypto isa"it will show you the the ikev1 and his ikev2.

  If you still see a flow in the table, maybe it's a stuck session.

  To disable the aggressive mode, enter the following command:

  Crypto ikev1 am - disable

  For example:

  HostName (config) # crypto ikev1 am - disable

• IPSEC of AnyConnect-IKEv2 authentication failure

  I have configure Anyconnect webvpn using IPsec (IKEv2) to an ASA with version 8.4 (2).

• AnyConnect IkeV2 backup server with test

  Hello world

  I configured anyconnect with ikev2 on our two different sites.

  Client PC have anyconnect pre configured on their PC.

  Under profile anyconnect each site I also put the IP address of the other ASA VPN site in the case where if users at site 1 connects to the ASA at site 1 so if this ASA is down they should automatically connect to Site 2 ASA.

  Want to know how I can test whether users are able to connect to the rear for the ASA.

  This test will be ok

  Turn off the ASA at site 1 and test the PC using name of Site 1 as Site 1 ASA connection is broken or turned off should it automatically connect to

  Back up the server who is ASA at site 2?

  Concerning

  MAhesh

  Yes, this test should do the trick, and give you an indication if the anyconnect client is toggled to the ASA secondary if the primary is unavailable.

• Restricting access via AAA auth group AnyConnect IKEV2

  Hello world

  I have config ASA with 2 groups of connection

  Say Group 1 and 2.

  Both are currently assigned to the same Auth AAA group

  One of our external suppliers has access to these two files group of connections 1 and 2 XM...

  If I want the seller must only connect to connect to the Group 2 should I change the Group AAA auth for Group 2 of the connection?

  Then, even if he tries to connection group 1 should not function as a group AAA Auth will only affect Group 2 right?

  Concerning

  Mahesh

  Mahesh

  If you have a single authentication server (or a pair of servers in operation HA), then it would seem that the seller would be authenticated any group, they are trying to access.

  I have a client who was using the function of blocking the group to accomplish something similar to what you describe. They used the RSA authentication two factors as you do so. They had the air was to send the authentication request to a Radius server. The Radius server would send the ID and code is entered at the RSA to do the authentication to the Radius Server and two factors would also querry Active Directory to learn more about membership in a user group. The Radius server then would return the results of the RSA and ED to the ASA group that would use the group lock feature to ensure that the user entered the right group. Maybe something like that might work for you?

• Type of cert for ikeV2 anyconnect

  Hello world

  I created the CSR for anyconnect IkeV2.

  When I ask the seller to cert that I should ask them what type of certificate that I needed for IkeV2?

  We do not want users to use ssl as https://xyz.com and to connect and download the client.

  We want machine pre installed with anyconnect and profile users and connect using IkeV2.

  Concerning

  Mahesh

  Each certificate provider has their own list of choices. Many understand Cisco among their choices. that is to say:

  http://www.InstantSSL.com/SSL-certificate-support/csr_generation/SSL-CER...

  In General, a standard server certificate just because we don't do a lot of fancy with it - just check identity. CN in the CSR must match the FQDN in this case...

• Cisco Anyconnect VPN vs IPSec AnyConnect SSL

  Hello

  Can someone tell me what is the difference between the Anyconnect SSL VPN and Anyconnect VPN IPSec.

  When we use one and not the other?

  Thank you very much.

  Best regards.

  Hello Abdollah,

  AnyConnect based on the SSL protocol is called Anyconnect SSL VPN and if you deploy Anyconnect with the IPSec protocol, it is called IKev2.

  AnyConnect (via IKEv2 or SSLVPN) does not use a pre shared key to authenticate the user.  A certificate will be used to authenticate the user and the ASA of + pass and the certificate used to authenticate the user.  The XML profile is necessary just to use the Anyconnect IKEv2 client rather than the default of SSL when connecting to the ASA.

  Here is the doc announced some of the benefits of using Anyconnect with Ikev2 rather than SSL VPN.
  http://www.Cisco.com/en/us/docs/iOS-XML/iOS/sec_conn_ike2vpn/configuration/15-2mt/sec-cfg-IKEv2-Flex.html#GUID-6548042E-1E4C-416A-8347-00DCF96F04DF

  In essence, if you have a simple deployment, then you can go with the installation of SSL VPN and if you want to take advantage of additional features, you can use Anyconnect with IPSec.

  Kind regards

• IKEv2 VPN without using licensed SSL? (ASA-5512)

  Hi all

  I enabled Cisco 'Anyconnect Premium peers' for customer less connections vpn ssl, the obvious snag is that for Anyconnect ikev2 sessions he wants to use the SSL license pool instead of the IPSEC pool (which I have a lot of connection for 'peers VPN Total: 250' licenses.

  * Is it possible to configure Anyconnect to connect through IPSEC and use licensed IPSEC (while keeping Premium Anyconnect active peers)?

  * Should I consider 3rd third-party vpn outside Anyconnect clients?

  CyA

  Craig

  Remote access to sessions with IKEv2 will always consume a Premium license. Change for another customer will not help unless you change to a customer that uses the legacy technology with EasyVPN. But this should not be the solution.

  If you enable AnyConnect Essentials, you can use AnyConnect with IPSec the platform limit, but you cannot use the features award (as a clientless) more at the same time.

  In a situation like that where many AnyConnect-Sessions are necessary and only a couple of sessions without client, I installed AnyConnectEssentials on the ASA principal and deployed an another ASA only for VPN without client. Due to the high cost of premium VPN licenses, is much cheaper then buying the Premium licenses for all VPN users.

• With the help of ASA as a tool for deployment of profile Anyconnect

  I have a requirement to use a router ASR as a head of network clients Anyconnect IKEv2.  I want to use the ASA firewall to allow users (multiple operating systems - Win/Mac/Linux) for ease of deployment, download their respective Anyconnect customers as well as the required profile to connect to the ASR.  Note that the ASA is used only for AC and AC downloads profile, he participates in any VPN termination.  Users will just point their browser to the ASA firewall web page and download the client from HQ and the profile, then they will launch the AC and connect to the router ASR.

  My question is, is it possible?

  Thank you!

  I guess it should work even if I haven't tried it personally.

  Note that above ' ASA shows a screen connection in the browser window, and if the user meets the logon and authentication. So you have an SSL connection without client on the ASA FRONT to take the step "downloads the client...". ».

  You should be able, from here, download the client and profile and have the host of profile configuration to point to the address of the router ASR.

• Remote access VPN VPN Ping from ASA clients

  I would like to know if it is normal to not being able to traceroute or ping for VPN clients connected from the ASA command line? The VPN client and the connection works well at the moment. I can't ping / connect to the VPN and vice versa internal hosts. I can't ping however the ASA VPN client IP address himself well. I'm so split tunnel but that seems to work correctly based on the determination of route I ran.

  Can I have an IKEv1 and IKEv2 for VPN IPSEC configuration? I try to keep the IKEv1 VPN for the legacy Cisco VPN client while I began to roll on the AnyConnect IKEv2 client. Just end up creating a new configuration of VPN for the AnyConnect VPN (easier)?

  What is the purpose of the injection of the route the other way around? It seems to be against intuitive. I was hoping it say for VPN DHCP pool 32 come to me so I would not add static routes on my heart to point to the ASA for these ranges. This ASA is reserved for the VPN firewall not this traffic is not normally head to it. Right now I have just the static route for the 24 I use in the DHCP pool on carrots. I have of course the possibility to redistribute the beach many other ways with EIGRP / OSPF / RIP it seems to me that RRI was a nice way to do, but it doesn't seem to be.

  It probably all comes from me probably do not understand exactly how bits to pass through the firewall to the actual machine of the VPN client. You see only not an interface layer 3 for part of the ASA in the tunnel, according to me, is part of what confuses me.

  Basically, I followed this guide and added split tunnel and aaa via RADIUS which seem to work well. I can't emphasize enough that for all intent and purposes, it seems that the VPN works as it should now. Wait for this time I broke it a few hours while I was playing with various other orders lol.

  Thank you

  Tim

  Reference:
  ASA 5505 (base right now, license #labgear) 9.2 (4) running

  It is normal to not be able to ping remote VPN clients to the ASA's.  To be able to do outside the ASA IP address must be included in the field of encryption, which is not normally.

  Yes, you can use IKEv1 and IKEv2 at the same time.  However if you change consider using SSL.  It is best taken in charge and less painful.

  If you choose to ignore this advice, then I would create a new IKEv2 VPN rather than modify the existing and then migrate users through him.

  The reverse route injection does exactly what you describe.  They appear as static routes on the SAA, you will then need to redistribute in any routing protocol you like.  I wouldn't normally use for traffic of users, but for the traffic of a site when managing more complex failover scenarios.

  I recommend to stick to the single 24 static road in your kernel.

  Is it possible to create a VPN Anyconnect of RA with just the name of user and password + pre-shared key (Group) for the connection, as could do for ikev1 with cisco VPN client? I am running 8.4.X ASA code and looks like tunnel-group commands have 8.2.X somewhat change. If you change the group type of the tunnel for remote access, now there is no option for IKEv2 PSK.

  I'm getting old so I hope that it is not in another complaint curmudgeonly on the loss of functionality. :)

  Many small businesses do not want to invest in the PKI. It is usually a pain to deploy, backup, make redundant, etc..

  But it would be nice to have a bit more security on VPN other than just the connections of username and password.

  If this is not possible, it is possible to configure the Anyconnect customer to IKEv1 with PSK and name at the level of the Group client?

  If this is not possible, WTH did cisco end customer VPN cisco as a choice of VPN connection (other than to get more fresh mail of license)?

  I really hope that something like this exists still!

  THX,

  WR

  You are welcome

  In addition to two factors, you can also do double authentication (ie the two using the user name and password). Each set of credentials can come from a Bank of different identities.

  With this scheme, you can can configure a local user name (common) with password on the SAA (think of it as your analog PSK) and the other be the AD user identification information.

• AnyConnect using IKEV2 that allows access to the provider

  Hello world

  We have configured Anyconnect using IKEv2 for our internal users and it works fine.

  Recently I received the request of our management to allow our service provider to our network, but they do need full access to our internal network.

  This provider also uses the IKEv2 anyconnect to access their own internal network.

  What I've done is asked our IT guy provider to update their profile with info below xml

  
    
     XYZ.com
     XYZ.com

  where xyz.com is our ASA VPN hostname.

  Need to know what I have to config anyconnect new profile and political group to make it work, or can I only create new group policy for this provider?

  Concerning

  Mahesh

  Yes, it's a common use case Mahesh.

  Whenever you install remote access VPN, one of the things you have to decide is to tunnel all traffic, traffic tunnel to specified networks, or to exclude the tunneling for some networks.

  It is usually a case of "split tunnel" (these two types) or "no split tunnel" (or "tunnelall"). Since you want to tunnel all traffic, then follow a Setup for "tunnelall." It should look like:

  attributes of the strategy of group vendorgroup
  Ikev2 VPN-tunnel-Protocol
  Split-tunnel-policy tunnelall

  It is a good recent example in the next document in TAC.

• AnyConnect with IKEv2

  Hello world

  I have config Anyconnect with IKEv2 only no web launch and SSL is also turned off.

  I downloaded the anyconnect - anyconnect-victory - 3.1.05160 - k9.pkg on PC.

  tried to connect but no luck.

  Is that it is designed to work this way?

  Concerning

  Mahesh

  Yes - it's a way to do it.

  Profile .xml is a simple file (but critical) very small, you can copy manually the ASA to your PC as well as through the automatic method, which, as noted, requires customer services via the SSL on the SAA. If you have the correct .xml file (should specify transport IPsec) and AnyConnect on the PC client software, you don't need the ASA via SSL customer service.

  If you make the manual method, any future update profile must also be distributed manually.

• Anyconnect with IPSEC IKeV2 certificate requirement

  Hello world

  We are implementing Anyconnect with IKEv2.

  Need to know if I can do this without a valid CA certificate?

  Will this work with ASA self-signed certificate?

  Concerning

  Mahesh

  Mahesh,

  SSL is used only for a few initial steps ("customer service" - such as downloading AnyConnect package and profile.xml file) in a remote IPsec IKEv2 VPN access.

  As with the more familiar SSL VPN, you can use a self-signed certificate on the SAA in conjunction with IKEv2.

  Your customers will have to or click beyond the warning of the untrusted server every time or else install the certificate self-signed SAA in their store of trusted CA root. with a certificate issued by the CA public they can't do either of those things.

  There are a few excellent documents elsewhere here on CSC that you reference in your deployment. Here are the links to them:

  Reference #1

  Reference #2
