Block the wide use of old VPN client.
Hello
I would like to block connections that still use older versions of the VPN client software.
I use an ASA5510.
I can ask customers to use the new version, as provided on the SAA, but they can always refuse this.
To force the use of the latest version of the client, I have the ability to block older versions.
Anyone?
Thank you.
Bart
Hi Bart!
You can restrict the versions of the Client VPN connection to the asa using the 'rule-access-client' in your group policy attributes. With this command, you can restrict by type or the version of the client.
You can find details on how to use it in the following link, so you can restrict older versions you want to avoid:

I hope that works for you!
See you soon!

I've recently updated to 8.3.2 and I have been informed of these NAT changes, but even after reading the https://supportforums.cisco.com/docs/DOC-12569 I am still unable to rectify the communication network 192.168.100.0 VPN with hosts on 172.16.1.0 and 172.16.9.0.

There is no route to the address pool of vpn. Maybe that's the problem? I don't know than that used to work before we went to 8.4.
Check if the firewall is enabled on your host from the client ravpn and blocking your pings.

The CBAC &; VPN Client
I use soft Cisco VPN client behind a Cisco CCCB router running. What are the ports must be opened to allow the client VPN working properly?
I am currently using:
allow an esp
allow udp any any eq isakmp
These are necessary, but you may also need to open UDP 10000 to support NAT - T if IPSec must cross a NAT border along its way.
You'll also need allow beach access VPN client address to the IP address ranges whatever they are to be used in common. This is because packages through the ACL twice, once encrypted using ESP and ISAKMP, there not yet encrypted.
So, if the VPN client has a range of pool to say 10.1.1.0/24 and his contact only the acl 10.2.0.0/16 subnet would look like:
IP access-group extended VPNACCESS
allow an esp
allow udp any any eq isakmp
permit IP 10.1.1.0 0.0.0.255 10.2.0.0 0.0.255.255

Function of automatic update for the IPsec VPN Client
Hello.
Do you have anyone ever tried the PIX / ASA ' feature IPsec VPN Client Auto-Update?
(see also Document ID: 105606).
He wants to make sure that I understand this right.
The user will receive a popup of information telling him to download the latest version of the client? And then there start the update itself?
If so, this would mean that the user must have the rights of full adminsitative using a laptop.
From my point of view, full administrator rights on a laptop are prohibited - 100% and therefore the functionality would be totally useless.
Anyone who can tell me whether I am good or bad?
Best
Frank
Frank,
You are right, if the computer desktop or labtop is completely locked regarding the installation of the software the customer won't be able to install it, they may be able to download from the link that you configured in ASA, once they connect to your server ASA RA but with regard to the installation user's machine needs rights profile appropriate to be able to install it.

Connection to the VPN Client 5.0.07 returns error 443 (activity included)
I got the Cisco VPN Client to work on my windows 8.1 box, but my windows 10 box gives me some issues.
I am trying to connect to a Cisco VPN using Cisco VPN Client 5.0.07.0290. 10 Windows. The first Cisco VPN would not install and I discovered that I had to install Citrix DNE before installing Cisco VPN. I did it and now the Cisco VPN client installs fine.
Now, I get an error 443 with the following log information when I try to connect:

----Things I've tried:I took the SSL certificate to my computer that works (windows 8.1) and installed on my machine Windows 10 and ensured that it was valid. I then imported it in the Cisco client. It did not work.I checked the registry to ensure there was incorrect data in the DisplayName value, and that works.Any thoughts on what I might try next?Hello Onimallar,
I had this same problem with my Windows 64-bit 10. But on my 32-bit Windows 10 VM the Client VPN Cisco worked OK. So I looked into the differences. It seems that Setup 64-bit VPN client cannot change the network settings to add the network client 'DNE light filter' required for the properties of the network adapter.
I tried the Citrix DNE update, and while that helped Cisco VPN Client install successfully on my 64-bit machine, it would not establish a connection.
Using the differences, I removed the two of the DNE Updater and Cisco VPN Client, and then installed 64-bit Dell SonicWall VPN Client, as this has been installed in my VM 32 bits (the 32-bit version). This added the workstation network DNE filter of my 64-bit machine. I reinstalled the Cisco VPN Client successfully and was able to connect to a remote site with success.
It worked for me.
You can download the SonicWall VPN Client from:

Activate the Transparent Tunneling on the VPN client?
Hi, I can connect my Cisco using my Cisco VPN Client hub if I turn off the transparent tunnel option or turn it on by using either IPsec over UDP or IPsec over TCP, one of these 3 options provide the best security or speed, or am I OK just to use the default value for my users that is active transparent and IPsec via UDP?
Thank you
IPsec over udp is fine. If you disable it, you'd probably find people difficult to establish communications behind nat devices. I do not think it is safer than the other, but I think udp is faster than tcp.

Hello
I set up a lab for RA VPN with a version of the ASA5510 8.2 and VPN Client 5 software using digital certificates with Microsoft CA on a Windows 2003 server. I did the configuration based on this document from Cisco's Web site:
Now, the vpn works fine, but now I need to configure a tunnel-different groups so I can provide different services to different users. The problem I have now is that I don't know how to set it up for the certificate is the name of tunnel-group. If I do an ASA debug crypto isakmp I get this error message:

% ASA-713906 7: IP = 165.98.139.12, connection landed on tunnel_group DefaultRAGroupSo, basically, when using certificates I connect always VPN RA only with the group default DefaultRAGroup. Do I have to use a model of different web registration for application for a certificate instead of the user model? How can I determine the OU on the user certificate so that match tunnel-group?
Please help me!
Kind regards
Fernando Aguirre
You can use the group certificate mapping feature to map to a specific group.
This is the configuration for your reference guide:
http://www.Cisco.com/en/us/partner/docs/security/ASA/asa82/configuration/guide/IKE.html#wp1053978
And here is the command for "map of crypto ca certificate": reference

VPN client and ssh to the external interface of the ASA
Hello world
I was testing clientless ssl in my lab at home.
When you're connected via vpn without customer, I am able to ssh ASA outside interface, but when I use ssl vpn only I can't ssh to the external interface of the ASA.
Need to figure out how I can ssh to the external interface of the ASA using clientless ssl vpn?
Concerning
MAhesh
Mahesh,
When you are on clientless SSL VPN to your customer is not limited routes of the Internet, isn't being NATted etc. If ASA is set to allow ssh from outside, then the VPN SSL without client user is no different from any other.
A the user SSL VPN full tunnel can have any or all of these factors at play. One of them can cause the impossibility to access the ASA outside interface via ssh. I see the configuration to tell you which one (or more) is to blame.

Professional Windows Vista crashes when you use Cisco VPN Client 5.05.0290
I have a Dell Latitude E6400 Windows Vista Business (32 bit) operating system. When I go to turn on the VPN client, I get invited to my username / password and once entered, the system just hangs. The only way to answer, it's a re-start. I took action:
1 disabled UAC in Windows
2 tried an earlier version of the VPN client
3. by the representative of Cisco, I put the application runs as an administratorIf there are any suggestions or similar stories, I would be grateful any offereings.
It IS the COMODO Firewall with the 5.0.x CISCO VPN client that causes the gel. The last update of COMODO has caused some incompatibility. I tried to install COMODO without the built in Zonealerm, but it is still frozen. The only way to solve it is to uninstall COMODOD. Since then, my CISCO VPN client works again...

Erik,
Please check it out because no decaps means the ASA does not what it is the other side of the tunnel.
If you send traffic and you will see the crypt increment... but nothing in return... 99% sure that the problem is at the other end.

VPN Client AnyConnect 5 migration
Dear community
We are migrating the old Cisco VPN Client 5-Cisco AnyConnect.
I have a couple of ASA-5510 9.1 (1) running the code with a license Base and in the current configuration, all remote users is in the VPN using standard methods of IKE/IPSec with their laptops (no split tunneling, nothing fancy). The VPN Client currently has a profile that is imported into each user's computer and has a pre-shared key that is stored, the solution works very well.
Management has decided to go for the more AnyConnect version, rather than Apex which I believe meets all our requirements (preview here: http://www.cisco.com/c/en/us/td/docs/security/vpn_client/anyconnect/anyconnect40/feature/guide/anyconnect40features.html).
I have three questions about the migration of Client AnyConnect VPN:
(1) currently my ASA shows that AnyConnect is disabled (see attached screenshot to see the version). Can I upgrade the license on my ASA? If what comes with AnyConnect or do I need to order it separately?
(2) is it possible to use the AnyConnect VPN Client VPN profile or should I create a new one?
(3) can someone direct me to a guide for remote access VPN configuration using the rather than the old VPN Client AnyConnect client? Are there any caveats / pitfalls, I should be aware of?
Thank you very much!
Best regards
Martin1 order the AnyConnect license you will get a PAK that you can redeem on the auto-serivce portal to get an activation key for your ASA. (You will need the serial number ASA as well.) This will allow you to "Essentials" AnyConnect (former name for more have together (which now includes Mobile), more or less) and allow you to run the command "anyconnect essentials".
2. the old style IPsec profiles channel not again SSL VPN ones.
3. There are many many of them out there. If you are new to it, you can find Pete Long message on the blog useful How - to's:
-
I could not connect using Mac OSX VPN Client 4.9. The "DEL_REASON_PEER_NOT_RESPONDING" message continues to appear. The log is attached.
Think you that requests connection to the VPN server. Newspapers, looks IKE packets never make to the customer. Could be a firewall on the client that blocks the IKE/IPSEC traffic or Server VPN itself does not. If he's the only successor client, check for the personal firewall or a firewall device blocking traffic.
