VPN Client 3.6.3 question
We use the PIX 515E (ver 6.2 (2)) like a VPN for remote users solution. The PIX uses OF and does not have the license for 3DES. Remote users have no problems to access the PIX using Cisco VPN Client 3.5.2 but cannot access using Cisco VPN Client 3.6.3. When I went on the website to download the new client (3.6.20, he mentions that there's 3DES. The new customer is not step in if that is what sustains the PIX?
Thank you
3.6 client introduces features for AES encryption. Unfortunately, they had to drop some types of existing encryption of the client to respond to this.
From the release notes (http://www.cisco.com/univercd/cc/td/doc/product/vpn/client/3_6/361_clnt.htm), you'll see that SHA/DES is no longer supported / offered by the customer, so if you have the following line in your PIX:
> crypto ipsec transform-set esp - esp-sha-hmac
then you will need to:
> crypto ipsec transform-set esp - esp-md5-hmac
Customer step in, it just does not DES/SHA more.

As far as I know that VPN (anyconnect or ipsec) clients or the firewall is not a restriction that each client that connects and establishes a VPN session must have a single public ip address. Let explain me, if we have 10 people (contractors) works in an office behind a firewall remotely, share one public IP address and we do not want to create a site to site vpn connection, then these 10 people can always use anyconnect VPN in the seat.
They all share the public IP address same, single address when they VPN in HQ.
Hello
Yes, all people in a remote region will be able to connect to the Central Office with the AnyConnect client, even if they have the same public IP address.
This is the case, because different clients AnyConnect sessions will be different source TCP ports.What IPsec and old Cisco VPN Clients? The situation should be the same, the VPN Clients because Cisco are behind NAT. Thus, they will have to use NAT-traversal and UDP 4500 to encapsulate the session of ESP. And UDP there is also used different source port numbers.

Classic question: SSL VPN Client and Vista 64 - bit OS
Material: 64-bit software architecture: Windows Vista Home Cisco Hardware (64-bit): 871w router Cisco Software: base of 12.4 T having a challenge with Windows Vista (64) using the SSL VPN. Use of IE, I can navigate to the url, both using the DNS name and IP address. I do not have a signed certificate, so I get the standard warning screen where you will need to click on the red x to continue. At this point, the progress bar moves for a fraction of a second and it's there. For troubleshooting I tried: - clearing cookies, cache, etc. - add url and IP to the Zone of confidence - reset areas rest default - disabled options window popup and phisher IE7 - off all 3rd party Manager BHO - withdrawal of MacAfee software suite - disable User Control that allowed me to make the sign in page, but after the signature - I had a blank white screen. Then, I downloaded Firefox 3.0 (newer) and tried to connect. After a series of guests to accept and download the certificate, I was able to connect and click on the Start button to start the session. The next little screen came as expected and he chose Java. I received a message that it could not install the Cisco AnyConnect Client's and I had to download it manually. Downloaded and installed the client software. Logging out of the browser and its closure - I could not access the page again. It appeared to hang again with a progress bar. I went to empty cache, cookies, passwords etc in Firefox and reloaded the application. Still, I was able to connect. However, I always received the message that the customer could not install and download manually. For fun, I exported the certificate on the desktop and imported into Internet Explorer. I tried the connection with IE, but he had a similar problem. I was told there was no client IPSEC for OS 64 bit (Vista at startup), but most of the new machines are 64 - bit OS systems. I would appreciate any support. Lucky me, the computer to which it is impossible to connect to the VPN is the home of the CEO of the company. The last person that wants to make him miserable.
Cisco AnyConnect VPN Client is now available for the Windows operating systems, which includes Vista 32 and 64 bit. The Cisco AnyConnect VPN Client, Version 2.2 supports SSL and DTLS. It does not support IPSec at the moment.

Question: how to assign the VPN IP VPN client user using 5.4 ACS?
I'm new to ACS5.4. What I want to achieve is to leave the ACS5.4 to assign IP addresses to users who are connecting to our ASA using the Cisco VPN client. ASA runs as a Radius of ACS5.4 client, and we have tested successfully for Radius Authentication. But users always get "unknown error" in the client VPN, after to be authenticated successfully. I think I used probably incorrect RADIUS attributes to an authorization policy. Here's what I did:
1. in the elements of the policy-> authorization permissions->-> authorization of network access profiles, I created a new profile and this profile is called the Radius CVPN3000/ASA/PIX7.x-DHCP-Network-Scope attribute. An IP address is entered under this attribute as a static value.
2. then, in access policies-> services-> client VPN IPSec with RADIUS Access (it's politics that I created)-> permission, I created an authorization policy allowing RADIUS previously created profile in order to be used.
I missed something? Maybe I got the wrong RADIUS attribute? Thanks in advance for any help!
ACS 5 doesn't have the ability to provide the IP addresses between the pools of IP addresses defined in ACS.
You must assign static users on basis by user on ACS 5. You can also create a pool on the SAA and tap the name of the ACS 5 pool

Unable to connect to other remote access (ASA) VPN clients
Hello
I have a cisco ASA 5510 appliance configured with remote VPN access
I can connect all hosts on the INSIDE and DMZ network, but not able to access other clients connected to the same VPN.
For example, if I have 2 clients connected to the VPN, customer and CustomerB, with a pool of vpn IP addresses such as 10.40.170.160 and 10.40.170.161 respectively, these two clients are not able to communicate with each other.
Any help is welcome.
Thanks in advance.
Hello
I'm a little rusty on the old format NAT, but would be what I would personally try to configure NAT0 on the 'outer' interface.
It seems to me that you currently have dynamic PAT configured for the VPN users you have this
NAT (outside) 1 10.40.170.0 255.255.255.0
If your traffic is probably corresponding to it.
The only thing I can think of at the moment would be to configure
Note of VPN-CLIENT-NAT0-access-list NAT0 for traffic between VPN Clients
list of access VPN-CLIENT-NAT0 permit ip 10.40.170.0 255.255.255.0 10.40.170.0 255.255.255.0
NAT (outside) 0-list of access VPN-CLIENT-NAT0
I don't know if it works. I did not really have to configure it on any ASAs running older software. There was some similar questions here on the forums for the new format.

Routing problem between the VPN Client and the router's Ethernet device
Hello
I have a Cisco 1721 in a test environment.
A net 172.16.0.0/19 simulates the Internet and a net 192.168.1.0/24 simulates the net, the VPN tunnel must go to (intranet).
The net 172.16.0.0 depends on the router 0 FastEthernet, Intranet (VPN) hangs on Ethernet 0.
The configuration was inspired form the sample Configuration
"Configuring the Client VPN Cisco 3.x for Windows to IOS using Local extended authentication"
and the output of the ConfigMaker configuration.
Authentication and logon works. Client receives an IP address from the pool. But there's a routing problem
side of routers. Ping client-side - do not work (the VPN client statistics that count encrypt them packets, but not to decrypt).
Ping the router works too, but decrypt and encrypt customer statistics in VPN packets count progressive
(customer has a correct route and return ICMP packets to the router).
The question now is:
How to route packets between the Tunnel and an Ethernet device (Ethernet 0)?
conf of the router is attached - hope that's not too...
Thanks & cordially
Thomas Schmidt

Thomas,
Can't wait to show something that might be there, but I don't see here. You do not have the card encryption applied to one of the interfaces, perhaps it was not copied. Assuming your description you do it, or should it be, applied to the fa0 and you are connected. Try how you ping? Since the router or a device located on E0? If you ping the router, you will need to do an extended ping of E0 to the ip address of the client has been assigned. If your just ping the router without the extension, you will get sales and decrypts that you declare on the client. Have you tried to ping from the client to interface E0? Your default route on the router is pointing to fa0? You have a next hop to affect? You have several NIC on the client pc? Turn off your other network cards to check that you don't have a problem with routing on the client if you have more than one.

Hello
Client VPN-{Internet} - CVPN - LAN
* Client (physical IP) has overlapping network as the LAN behind the CVPN.
* There will be questions?
* VPN client pool is different from the LAN behind the CVPN.
* This configuration will work.
As stated, I know:
* Avoid any problem except for the fact that the connected vpn client once will not be able to navigate to its local network.

Hi Adi
You'll land with problems related to the delivery. Its is very rare that the customer would connect that same because local and remote identities.
Normally, you would see one like 0.0.0.0 and the other internal IP range.
This is not a recommended thing.
With the cliet 4.x, we can make it work by changing routes to each machine. He looks up in Jean Marc page you might find a DDT on this as well.
Hope this helps

The VPN client VPN connection behind other PIX PIX
I have the following problem:
I wanted to establish the VPN connection the client VPN to PIX on GPRS / 3G, but I didn t have a bit of luck with PIX IOS version 6.2 (2).
So I upgraded PIX to 6.3 (4) to use NAT - T and VPN client to version 4.0.5
I have configured PIX with NAT-T(isakmp nat-traversal 20), but I still had a chance, he would not go through the 1st phase. As soon as I took nat-traversal isakmp off he started working, and we can connect to our servers.
Now, I want to connect to the VPN client behind PIX to our customer PIX network. VPN connection implements without problem, but we can not access the servers. If I configure NAT - T on the two PIX, or only on the customer PIX or only on our PIX, no VPN connection at all.
If I have to connect VPN client behind PIX to the customer's network and you try to PING DNS server for example, on our PIX, I have following error:
305006: failed to create of portmap for domestic 50 CBC protocol translation: dst outside:194.x.x.x 10.10.1.x
194.x.x.x is our customer s address IP PIX
I understand that somewhere access list is missing, but I can not understand.
Of course, I can configure VPN site to site, but we have few customers and take us over their servers, so it'd just connect behind PIX VPN and client connection s server, instead of the first dial-in and then establish a VPN connection.
Can you please help me?
Thank you in advan

Question:
Hi Glenn,.
Following is possible?
I have the vpn client on my PC, my LAN is protected by a pix. I can launch the vpn client to connect to remote pix. Authenticates the vpn client and the remote pix makes my PC with the assigned ip appropriate to its pool of ip address.
The problem that I am facing is that I can not anything across the pix remote ping from my PC which is behind my pix. Can you please guide me what I have to do to make this work, if it is possible?
My PC has a static ip address assigned with the default gateway appropriate pointing to my s pix inside interface.
Thank you very much for any help provided in advance.
Response from Glenn:
First of all, make sure that the VPN connection works correctly when the remote PC is NOT behind a PIX. If that works fine, but then breaks when put behind a PIX, it is probably that the PIX is PAT, which usually breaks IPSec. Add the following command on your PIX VPN client is behind:
fixup protocol esp-ike
See http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref/df.htm#wp1067379 for more details.
If it still has issues, you can turn on NAT - T on the remote PIX that ends the VPN, the client and the remote PIX must encapsulate then all IPSec in UDP packets that your PIX will be able to PA correctly. Add the following command on the remote PIX:
ISAKMP nat-traversal
See http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref/gl.htm#wp1027312 for more details.
NAT - T is a standard for the encapsulation of the UDP packets inot IETF IPSec packets.
ESP IPSec (Protocol that use your encrypted data packets) is an IP Protocol, it is located just above IP, rather than being a TCP or UDP protocol. For this reason, it has no TCP/UDP port number.
A lot of features that make the translation of address of Port (PAT) rely on a single to PAT TCP/UDP source port number ' ing. Because all traffic is PAT would be at the same source address, must be certain uniqueness to each of its sessions, and most devices use the port number TCP/UDP source for this. Because IPSec doesn't have one, many features PAT fail to PAT it properly or at all, and the data transfer fails.
NAT - T is enabled on both devices of the range, they will determine during the construction of the tunnel there is a PAT/NAT device between them, and if they detect that there is, they automatically encapsulate every IPSec packets in UDP packets with a port number of 4500. Because there is now a port number, PAT devices are able to PAT it correctly and the traffic goes normally.
Hope that helps.

VPN client can get the gateway?
I have a question for a long time.
Cisco vpn client will find a gateway to the remote vpn server address.
There are many situations in which we need a gateway assigned to the vpn client. If the customer can freely access all private networks.
PIX of Cisco router has this feature?
Why the customer would need a bridge tunnel?
The customer already has a gateway of the ISP.
Once the tunnel is up, if not to do split tunneling, all customer traffic will be sent on to the CONCENTRATOR's IPSec tunnel. So, indeed, the HUB is the default gateway.
If you use the split tunneling, then your ACL will say what customer traffic must be encrypted on the tunnel on the hub. All other traffic is sent clear for the ISP. So, indeed, the HUB is the gateway for the LAN within the tunnel.
There is a featur default on the 3000 gateway Tunnel, but that's for a different purpose

Using VPN Client coming out behind a PIX
As I understand it, a PIX can operate as a VPN endpoint for IPsec tunnels, or allow IPsec traffic to pass to the other endpoints behind him; My PIX is an end point, but there are a few users who wish to use the VPN Client to connect to outside points beyond the firewall.
Is it possible to configure a PIX to two pass through IPsec traffic AND be an endpoint?
On a related note, two customer software VPN hosts can connect to each other?
Thank you
Marc
My pix company does exactly what you posted, there is lan - lan vpn, and we again establish vpn to other companies via a software vpn client.
concerning the transmission of described video, it should not need additional acl or configuration assuming that there is no acl on the pix. a question must be noticed is that the other end (i.e. the end point of the remote vpn client) needs to nat-traversal since the local pix usually perform nat/pat.
However, the vpn directly between two clients is not feasible as its name suggests (they are the two client).

CISCO ANYCONNECT VPN CISCO VPN CLIENT
Hi, I was in the process of configuring cisco anyconnect vpn for ip phones to our local obtained the license for them either, the question that I get is that I already have remote configured cisco connect via the old cisco vpn client.
now, if I activate the anyconnect ssl on the same outside the interface both can exist without conflict or maybe I need to migrate users to install the end customer for anyconnect system software to connect.
I also need help with authentication of certification.
concerning
You can run both VPN at the same time without problems.
However, you should try and migrate everyone to the latest technology Anyconnect SSL anyway.

Win 7 VPN client cannot access remote resources beyond the VPN server
I have a Win 7 laptop with work and customer Win 7 VPN set up, and through it that I can access everything allowed resources on the remote network.
I built a new computer, set up the Win 7 client with the exact same parameters everywhere, connected to the VPN with success, but can not access any of the resources on the remote network that I can on my laptop.
Win 7 64 bit SP 1
I did research online and suggestions have already had reason of my new set up. In addition, I have a second computer that I've set up the VPN client, and I'm having the same problem. VPN connects successfully, but is unable to access the resources.
Tested with firewall off the coast.
Troubleshooting Diagnostic reports: your computer seems to be configured correctly, distance resources detected, but not answered do not.
I created another VPN client on the new computer to another remote network and everything works perfectly.
Remember the old VPN connection to the remote network that does not work on the new computer works perfectly on Win 7 64 bit laptop computer.
So, what do I find also different between identical configurations "should be" where we work and two new machines is not?
It must be something stupid.

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:
