Cisco VPN :: Two ASA (v8.4) - IKEv1 And IKEv2 Session In ASDM Monitor?
Oct 25, 2012
I have a L2L tunnel setup between two ASA's (v8.4). I used the wizard to set these up and selected the defaults of both IKEv1 and IKEv2, thinking that it would select one or the other. The strange thing is that now I see a separate session between these ASA's, one for IKEv1 and one for IKEv2. Both are passing traffic. Is this expected behavior? Should I disable IKEv1 to force only v2 since both are v8.

If I implement IKE V2 on Cisco ASR 1006 Router or on firewall and sets up IPsec with IKEv1 device ( Cisco Router , Juniper etc )will it work or not ?

I've setup and configured the following local monitor session on a 7606 but it doesnt seem to be outputing anything. Any guess as to why, or what I might be doing wrong? Gi1/1 is doing ~40Mb/s egress & 15Mb/s ingress. Both source and destination ports are routed ports.
monitor session 10 source interface Gi1/1
monitor session 10 destination interface Gi1/10 ingress
interface GigabitEthernet1/1

-monitor session 1 dest int fas 5/0/24
-monitor session 1 src int fas 5/0/34

For the command "monitor session 1 source" in Cat4900 (e.g. 4948), how many source interfaces can be supported per monitor session?

We have 2 6513 switches with SUP720/PFC3A and various POE modules and a 6748-GE-TX facing our servers. Additionally, we have a 4Gbps portchannel trunk interconnecting the switches. We have approximately 300 Nortel IP 1140e phones in use between the two switches.For the purpose of call recording, we've attempted to mirror the voice vlan using various approaches and have been met with limited success. We mirrored the VLAN using tx, rx, and both. When using both we appear to get duplicate packets at the destination interface.We seem to lose packets completely going in one direction or another for a given call. Packets are lost before they get to the destination interface?

I have a 2821 Router with several IPSec Tunnels on it. I would like to replace this with a ASA 5510. My hope is to swap these out with minimal impact on the active Tunnels. I have the details of each Tunnel well documented. My question or concern is in configuring the Tunnels on the ASA. Do I need to configure IKE proposals in just IKEv1? If I use IKEv2, my concern is that there will be compatibility issues with the remote end of the Tunnels, or is IKEv2 functional with IKEv1? If not, then, do I just configure everything in IKEv1 and ignore IKEv2?

just upgraded my ASA5510 from IOS 8.25 to 8.42Everything is running fine apart from one VPN between ASA5510 and cisco 887V router.The VPN session is up but no data traffic is being passed through The tunnel although this VPN was working fine with old IOS. The tunnel is up but no data is passing through IKEV1 session.

I connecting to a Cisco ASA 5500 using a third party IKEv1 client. The initial connection and all rekey attempts that start on the client are successful. A tunnel is established, data cna be transferred between the client and the ASA's internal network etc.However, when the ASA initiates rekeying of a Quick Mode SA this is rejected on the client. The rejection occurs due to QM3's HASH payloading having a length of 4, which is wrong.
ASA log:
ISAKMP Header
Initiator COOKIE: 48 81 9e 1b 80 94 41 a9
Responder COOKIE: fa ab 87 c7 a5 d9 8d 35
Next Payload: Hash
Version: 1.0
Exchange Type: Quick Mode
[code]...
Since the initial negotiations work, pre-shared key, IKE/IPsec settings etc should be correct; if they weren't the connections wouldn't work in the first place.

I've enabled Cisco "Anyconnect Premium Peers" for client less ssl vpn connections, the obvious catch is that for ikev2 Anyconnect sessions it wants to use up the SSL license pool instead of the IPSEC pool (which I have lots of connection licenses for "Total VPN Peers : 250".
* Is there any way to configure Anyconnect to connect via IPSEC and use an IPSEC license (while keeping the Anyconnect Premium Peers enabled)?
* Do I have to consider 3rd party vpn clients, outside Anyconnect?

I have been working for a while trying to get the Linux AnyConnect Client to Connect to the ASA using IKEV2 and EC Certs. I have gotten it to work with SSL, but I can't seem to figure out how to get IKEV2 turned on. On the profile screen (attached) in the ASA when I check IKEV2 I get the cert screen, I check the cert, but then it fails to bring the cert and unchecks the block. The Network Design is simple. ASA IP on high side (outside) 172.20.206.8 with the client at 172.20.206.50. Local LAN is at 10.200.203.0/24.

We are testing the AnyConnect VPN Client to replace legacy IPSec VPN Client 5.0.x. We could setup the connections with SSL and IPSec (IKE v2).Now we have to decide which ist the better method.

i have a little 877 router running Version 12.4(24)T2. I want to muck around with an IKEv2 IPSec VPN but i can't find anywhere to configure IKEv2.
I have found some doco that says its under the crypto config, something like router(config)# crypto ike2 ...........
But i don't have that option. Is it anywhere else?

I seem to be unable to access any IKEv2 features. The command crypto ikev2 is not available. Everything I've read suggests IKEv2 is available in this IOS version.Is there something I'm missing?

I have 2 ASA5505's connected through a site-to-site using IKEv1 and IKEv2.Recently, I ran through the wizard to configure the AnyConnect software. [code]Now, my site-to-site connection will only come up using IKEv1.Is there a way to have both the Site-to-Site and the AnyConnect VPN connections use IKEv2?

I have Any Connect (ver 3.1.01065) configured on Cisco router 891. VPN is working fine from the desktop, but I also need the ability to establish a VPN connection through a RDP connection (i.e. I'm using RDP to connect to a PC which has AnyConnect installed on, then trying to establish a VPN connection). OS Windows 7 SP1 x86.I've read about changing some settings in profile file (changed the <WindowsVPNEstablishment> option to "AllowRemoteUsers". Then applied the profile to the relevant Group Policy. Connected VPN from the PC (not through RDP), so that it downloads the new profile, and then disconnected again.): url...
But this make sense to the cisco asa... I have a cisco router on the ios 15.1. I've checked the XML file on the local PC to confirm the profile has been downloaded and is has, and I can't see the AllowRemoteUsers option.So I still can't start VPN through an RDP connection. (Error is "VPN establishment capability from a remote desktop is disabled. A VPN connection will not be established".)This also happened with the previous version of AnyConnect (2.5.xxxx).The PC's local routing tables look fine, and I can't see any conflicts that would cause the RDP session to drop.In the main window of Cisco anyconnect secure mobility client Ive noticed label: Web Authentication required.

I have configured my Cisco 881 and finally got past the "Cannot see my network" with IPSec VPN issue.I have a usecase where I need to access the gateway from the VPN Session.When I connect to the VPN using Cisco VPN Client 4.8x, I do not get back a Default Gateway on the VPN Adapter. When I try to ping my LAN Gateway IP (10.20.30.1) it does not respond and I cannot access it with any other tools.I am pretty sure this is a very ACL issue and it makes sense to hide the gateway by default but the big question is how do I configure my router to see the Gateway and be able to access it from the VPN session?
