VPN Cisco IPSEC - ISAKMP id_connexion
Hi Experts,
We have a site to site VPN IPSEC between a router Cisco 1801 and 800F fortigate firewall.
Works VPN, but a quesiton that I are just Conn Isakmp id changes very frequently and I wanted to just make sure that I understood why.
When I run the isakmp crypto to show its command, I get the following:
IPv4 Crypto ISAKMP Security Association
DST CBC conn-State id
1.2.3.4 5.6.7.8 QM_IDLE 2455 ACTIVE
1.2.3.4 5.6.7.8 2454 MM_NO_STATE ACTIVE (deleted)
In the time it took me to write this, it has changed:
IPv4 Crypto ISAKMP Security Association
DST CBC conn-State id
1.2.3.4 5.6.7.8 QM_IDLE 2457 ACTIVE
1.2.3.4 5.6.7.8 2456 MM_NO_STATE ACTIVE (deleted)
1.2.3.4 5.6.7.8 2455 MM_NO_STATE ACTIVE (deleted)
So, for me it looks like the phase ISKAMP 1 re-lance his SA very frequently. I put the ISAKMP policy as follows:
World IKE policy
Priority protection Suite 10
encryption algorithm: three key triple a
hash algorithm: Message Digest 5
authentication method: pre-shared Key
Diffie-Hellman group: #5 (1536 bit)
lifetime: 86400 seconds, no volume limit
Therefore, should - that means that the Phase 1 SA should only re-iniate 86400 seconds?
Any information would be appreciated,
Thank you very much
Jonathan
Hello
It seems you have DPD (isakmp crypto KeepAlive) configured on your router. This determines the accessibility of the other VPN endpoint, and we are not to understand thanks for the packages "R U THERE" (due to the problem of the DOI) that we send them, ISAKMP marks the tunnel as death and tears down.
Traffic on the tunnel seems so the tunnels, and then DPD expires them again.
Flip through your configuration for the "keepalive" order and if it is set for periodicals, set the KeepAlive for 'on demand' (which should be the default) so that we only send DPD when we are unable to determine whether the tunnel is alive because no traffic is coming on it.
This doc link is old, but he describes the functionality well enough:

Cisco VPN Client and Windows XP VPN Client IPSec to ASA
I configured ASA for IPSec VPN via Cisco VPN Client and XP VPN client communications. I can connect successfully with Cisco VPN Client, but I get an error when connecting with the XP client. Debugging said "misconfigured groups and transport/tunneling mode" I know, they use different methods of transport and tunneling, and I think that I have configured both. Take a look at the config.
PS a funny thing - when I connect with client VPN in Windows Server 2003, I have no error. The only difference is that client XP is behind an ADSL router and client server is directly connected to the Internet on one of its public IP of interfaces. NAT in the case of XP can cause problems?

Hello
For the Cisco VPN client, you would need a tunnel-group name configured on the ASA with a pre-shared key.
Please see configuration below:
http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a00805734ae.shtml
or
Please see the section of tunnel-group config of the SAA.
There is a tunnel-group called "rtptacvpn" and a pre-shared key associated with it. This group name is used by the VPN Client Group name.
So, you would need a specific tunnel-group name configured with a pre-shared key and use it on the Cisco VPN Client.
Secondly, because you are behind a router ADSL, I'm sure that's configured for NAT. can you please activate NAT - T on your ASA.
"crypto isakmp nat-traversal.
Thirdly, change the transformation of the value
raccess 1 set transform-set vpnclienttrans crypto dyn1 dynamic-map
Let me know the result.
Thank you

IPSec site to site VPN cisco VPN client routing problem and
Hello
I'm really stuck with the configuration of ipsec site to site vpn (hub to spoke, multiple rays) with cisco vpn remote client access to this vpn.
The problem is with remote access - cisco vpn client access - I can communicate with hub lan - but I need also communication of all lans speaks of the cisco vpn client.
There are on the shelves, there is no material used cisco - routers DLINK.
Someone told me that it is possible to use NAT to translate remote access IP-lan-HUB customers and thus allow communication - but I'm unable to set up and operate.
Can someone help me please?
Thank you

How the DLINK has been configured for traffic between the site to site VPN subnets? You are able to add multiple remote subnets on DLINK? If you can, then you must add the pool of Client VPN subnet.
Alternatively, if you cannot add multiple subnet on DLINK router, you can change the pool of Client VPN 192.168.6.0/24, and on the crypto ACL between the site to site VPN, you must edit the 180 existing ACL
DE:
access-list 180 allow ip 192.168.7.0 0.0.0.255 192.168.1.0 0.0.0.255
access-list 180 allow ip 192.168.200.0 0.0.0.255 192.168.1.0 0.0.0.255
TO:
access-list 180 allow ip 192.168.6.0 0.0.1.255 192.168.1.0 0.0.0.255
Also change the ACL 190 split tunnel:
DE:
access-list 190 allow ip 192.168.7.0 0.0.0.255 192.168.200.0 0.0.0.255
access-list 190 allow ip 192.168.1.0 0.0.0.255 192.168.200.0 0.0.0.255
TO:
access-list 190 allow ip 192.168.7.0 0.0.0.255 192.168.6.0 0.0.0.255
access-list 190 allow ip 192.168.1.0 0.0.0.255 192.168.6.0 0.0.0.255
Finally, replace the remote subnet 192.168.7.0/255.255.255.0 192.168.6.0/255.255.254.0 DLINK.
Hope that helps.

Hello
I just upgraded to macOS Sierra and built-in Cisco IPsec VPN no longer works. When you try to connect, I get a "cannot validate the certificate of the server. "Check your settings and try to reconnect" error message. I use Cisco ASA with self-signed certificates and everything worked fine with previous versions of OS X.
Please help me, I need my VPN Thx a lot
I am having the same problem with StrongSwan and help cert signed with the channel to complete certificates included in the pkcs12 file imported to the keychain. It was working properly in El Capitan, but now broken in the Sierra.

I looked at the configuration of your router RT-897VA once again, and I don't know if static NAT statements in there are supposed to work or not, but they won't because you have not specified any inside and outside interfaces.

the system still works, but I don't know why, we get the error log.
Thanks for any help you can provide!
Duyen
Hello Duyen,
I think I've narrowed the issue. When remote access VPN using RADIUS authentication we must keep in mind that authentication and authorization are included on the same package.
Depending on your configuration, the ACS is defined as a server RADIUS (Gserver Protocol radius aaa server) and becomes the VPN Tunnel authenticated and 'authorized' on this server group:
authentication-server-group LOCAL Gserver
authorization-server-group Gserver
As noted above, the RADIUS of request/response includes authentication and authorization on the same package. This seems to be a problem of incorrect configuration that we should not set up the 'permission' in the Tunnel of the group.
Please remove the authorization under the Tunnel of Group:
No authorization-server-group Gserver
Please test the connection again and check the logs of the ACS. At this point there are only sucessful newspaper reported on the side of the ACS.
Is 'Permission-server-group' LDAP permission when authenticating to a LDAP server so to retrieve the attributes of permission on the server. RAY doesn't have the command as explained above.
I hope this helps.
Kind regards.

Jabber of Cisco on Cisco ipsec VPN client
Hello
I wonder if anyone has had this problem. I am currently using the 9.2.3 J4W customer and when I use Jabber in my office, everything works fine. IM works very well and my incoming and outgoing calls work. The question I have is when I work from home on my personal wifi and customer VPN Cisco (version 5.0.07.0290) ipsec remote in my area that the instant messaging and presence features work fine however only outgoing calls work. With Jabber, I can dial any DN in my organization and a willingness to work. The only problem is when someone tries to call me, I'll never get an alert for the incoming call. However my ip back to my desk phone will be keep ringing and I'll see the voicemail and calls to jabber? For some reason any call does not make for me on my VPN session. I'm not sure of what could be the problem. Jabber has certain requirements on ipsec VPN to work? We use the ASA 5510 firewall and VPN endpoint.
Thank you

We recently had this problem: one of my other network admins had to prosecute with TAC, their resolution is to add
a static NAT on our ASA for external source outside translation is your VPN network, destination is your VPN network.
Thank you

Hello
I would like if it is possible to make the IPsec VPN connection as a customer.
ISP router (VDSL connection)
<--->Cisco 887 <---->pc more with conditional redirection
VPN router (as strongVPN)
Thank you for your help.
Best regards
Hi Bruno.
Yes the IOS router may be a VPN client, it is called easy VPN:
How to configure Easy VPN Cisco IOS (server and client)
* The server must be a Cisco device such as another router or an ASA.
Keep me posted.
Thank you.

Customer Cisco IPSec vpn cisco ios router <>==
Hello
I need to implement ipsec vpn for all users of 10-15. They all use the vpn cisco 5.x client and we have a router for cisco ios at the office. We already have a situation of work for these users. However, it has become a necessity which known only devices (laptops company) are allowed to install a virtual private network.
I think that the only way to achieve this is to use certificates. But we don't won't to buy certificates if there is a free way to implement. So my question is
(1) what are the options I have to configure vpn ipsec, where only known devices can properly configure a vpn and all unknown devices are blocked?
(2) if the certificate is the only way. Can I somehow produce these certificates myself using cisco router ios?
(3) someone at - it an example of a similar installation/configuration?
Thanks in advance.
Kind regards
M.
Unfortunately if you connect to the router IOS, there is no other way except using the certificate. If you connect to a Cisco ASA firewall, then you can identify the laptop company using DAP (Dynamic Access Policy).

Hi all
I am not cisco trained or worked with cisco, im a complete beginner in Cisco platforms. We are an IT support MPH and we have recently taken on a client that has an office abroad using a Cisco 881 device with a Draytek router to the United Kingdom. Site to site connectivity is necessary. I watched and watched videos of youtube on how to configure the VPN and think I have it in place by using the config on the cisco below:

Type to abort escape sequence.
Send 5, 100 bytes toICMP echoes, waiting time is 2 seconds:
.....
Success rate is 0% (0/5)I also can't ping the remote site in the Cisco lan.
I think that it is towards the end of cisco, the Draytek is a basic router and no routing is able to be configured. It does it automatically. The VPN is so no traffic...
Please can someone point me in the right directoin?
Thank you
The additional ip route does not harm even if it is not needed. I love these additional routes that they can serve as a sort of "online documentation" when it is used with a keyword "name" extra at the end.
Your NAT - ACL does not have the traffic. Just add the following:
ip access-list ext 102 1 deny ip
0.0.0.255 0.0.0.255 -
Client VPN Cisco router Cisco, MSW CA + certificates
Dear Sirs,
Let me approach you on the following problem.I wanted to use a secure between the Cisco VPN client connection
(Windows XP) and Cisco 2821 with certificate-based authentication.
I used the Microsoft certification authority (Windows 2003 server).
Cisco VPN client used eTokenPRO Aladdin as a certificate store.Certificate of MSW CA registration and implementation in eToken ran OK
Customer VPN Cisco doesn't have a problem with the cooperation of eToken.
Certificate of registration of Cisco2821 MSW ca ran okay too.Cisco 2821 configuration is standard. IOS version 12.4 (6).
Attempt to connect to the client VPN Cisco on Cisco 2821 was
last update of the error messages:ISAKMP: (1020): cannot get router cert or routerdoes do not have a cert: had to find DN!

This problem? There is someone who knows how to understand these mistakes?
Thank you very much for your help.Best regards

Problem with ping VPN cisco 877
Hi all!
I have a working VPN between a fortigate and a Cisco.
I have a problem with ping network behind the cisco of the network behind the forti.
When I ping to vlan2 cisco without problem (192.168.252.1) interface, but I can't ping a server in the vlan2 (192.168.252.2) behind the cisco.
However the Cisco I can ping the server. In the forti, I see that ping to the interface vlan2 and server in vlan2 take in the same way, and I can see package.
I post my config could see it it as blocking the ping from 10.41.2.36 to 192.168.252.2 while 192.168.252.1 ping is OK?

Customer VPN CISCO C2691 4.9.01.0180 does not work
Hello
After reading and find information about the client IPsec and VPN som, I now try to make it work, but:
The TEST LABORATORY is to follow:
INTERNET-> (IP 192.168.10.1/24) C1841-> INT0/1 TEST LAB

I can PING from the computer:

But when I run the VPN, I have no communication, the PASSWORD and LOGIN are correct with the scrip.

IPSec driver successfully stoppedThe manuscript in the CISCO 2691 is just suited for my setup, I don't think that I made a few mistakes, but you never know.
If has a first time, I'm able to establish a VPN connection to my computer and my router, I'll be happy, if I see my home network of the CISCO 1841 (ROUTER MAIN one) this will be perfect, that's also what I would like to check in.

Hi Didier,.
Looking at your first series of VPN client logs, it seems that the VPN client is set to use IPSec/TCP on port 10000 while CTCP has not been enabled on the router.
I suggest you to change the configuration on the client VPN IPSec/UDP rather than TCP. (Go to the tab "Transport" when you change the corresponding connection on the VPN client).
Let me know if this helps out!
See you soon,.

Configuration VPN Cisco ASA5505 new 800
I have 2 office buildings using routers Cisco 800 series with a L2L VPN between the two. I'm upgrading from the router to an ASA5505 at one of the offices but cannot understand the L2L VPN on the SAA. Specifically, may not know how to set the pre-shared key. On the Cisco 800 there:
ISAKMP crypto key
address This doesn't seem to work on the SAA. Can anyone help this? Here is my current config on the Cisco 800...
crypto ISAKMP policy 10
BA 3des
md5 hash
preshared authentication
Group 2
ISAKMP crypto key

Crypto ipsec transform-set esp-3des esp-md5-hmac DUMAC3

match address 101
access-list 101 permit ip 192.168.1.0 0.0.0.255 192.168.7.0 0.0.0.255
in your crypto-maps, the '10' and '65535' are the sequence numbers. A CM handset might look like this:
address for correspondence primaryisp_map 10 101 crypto card
