ASA allows 1 only RAS VPN Client IPSEC

Hi all

I have a strange problem where an ASA 5510 configured for IPSEC - over - udp VPN RAS allows only one 1 customer vpn traffic through.

Other clients can connect successfully (obtain IP/DNS etc., auth using LDAP) but only the all connected client is first able to browse internal resources. Others show 0 decrypted packets when I check the statistics. I have confirmed that it is not a problem with the license that the ipsec default license allows customers up to 250 I believe. Does anyone had this problem in the past?

TKS,

Donavan

It is usually a problem with the translations, which intervened on the NAT/PAT device in front of these multiple machines:

http://www.ciscotaccc.com/Kaidara-Advisor/security/showcase?case=K71102938

Check the translations look correct initially on this device. There should be a translation for each VPN.

There were also a few bugs on multiple clients behind the same PAT, such as CSCse03299, but these had to do with IPSec over TCP connections.

  • 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

    http://tinyurl.com/5t67hd

    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

  • Problems to connect via the Cisco VPN client IPSec of for RV180W small business router

    Hello

    I tried to configure my router Cisco of RV180W as a customer VPN IPSec, but have encountered a problem that I hope someone can help me with. "" I managed to do the work of configuration so that the Cisco's VPN IPSec client authenticates successfully with the XAUTH user, I put on the router, but during the negotiation, the client ends with the following, which appears several times on the router error message: ' Mar 20 Oct 19:41:53 2015 (GMT + 0000): [r1] [IKE] ERROR: local configuration for > [34360] has no config mode.

    I've read around the internet and a number of people seem to say that the Cisco VPN Client is not compatible with the router, but the same thing happens to my iPhone VPN client.

    Is it possible that this can be implemented? Below, I have attached the full configuration files and the log files. Thank you much in advance.

    Correct, the RV180 is not compatible with the Cisco VPN Client.  The Iphone uses the Cisco VPN Client.

    You can use the PPTP on the RV180 server to connect a PPTP Client.

    In addition, it RV180 will allow an IPsec connection to third-party customers 3.  Greenbow and Shrew Soft are 2 commonly used clients.

  • All necessary licenses on ASA 5510 for old Cisco VPN Client

    We're trying to migrate our firewall Watchguard to a Cisco ASA 5510, who bought some time ago. For some reason, all of our users have already installed the old Cisco VPN client. I think it will work. Are there licensing issues on the 5510 I had to be concerned with?  No matter what special config that needs to be done on the 5510?

    Fix. You don't require licensing of AnyConnect of any type of configuration and the use of IKEv1 IPsec remote access VPN (which use the old Cisco VPN client).

    You will be limited to 250 active IPsec peers (remote access more no matter what VPN site-to-site) by the platform (hardware) device capabilities that are enforced by the software.

  • Have problems with the IPSec VPN Client and several target networks

    I use an ASA 5520 8.2 (4) running.

    My goal is to get a VPN client to access more than one network within the network, for example, I need VPN client IPSec and power establish tcp connections on servers to 192.168.210.x and 10.21.9.x and 10.21.3.x

    Hello Kenneth,

    Based on the appliance's routing table, I can see the following

    C 10.21.9.0 255.255.255.0 is directly connected, DeviceManagement

    C 10.21.3.0 255.255.255.0 is directly connected, servers

    C 192.168.210.0 255.255.255.0 is directly connected to the inside

    And you try to connect to the 3 of them.

    Politics of Split tunnel is very good, the VPN configuration is fine

    The problem is here

    NO_NAT list of allowed ip extended access all 172.31.255.0 255.255.255.0

    NAT (inside) 0-list of access NO_NAT

    Dude, you point to just inside interface and 2 other subnets are on the device management interface and the interface of servers... That is the question

    Now how to solve

    NO_NAT ip 192.168.210.0 access list allow 255.255.255.0 172.31.255.0 255.255.255.0

  • Internet access with VPN Client to ASA and full effect tunnel

    I'm trying to migrate our concentrator at our new 5520 s ASA. The concentrator has been used only for VPN Client connections, and I have not the easiest road. However, I, for some reason, can't access to internet through our business network when I've got profiles with lots of tunneling.

    I've included the configuration file, with many public IP information and omitted site-to-site tunnels. I left all the relevant stuff on tunnel-groups and group strategies concerning connectivity of VPN clients. The range of addresses that I use for VPN clients is 172.16.254.0/24. The group, with what I'm trying to access the internet "adsmgt" and the complete tunnel to our network part is fine.

    As always, any help is appreciated. Thank you!

    Hüseyin... good to see you come back.. bud, yes try these Hüseyin sugesstiong... If we looked to be ok, we'll try a different approach...

    IM thinking too, because complete tunnel is (no separation) Jim ASA has to go back for the outbound traffic from the internet, a permit same-security-traffic intra-interface, instruction should be able to do it... but Jim start by Hüseyin suggestions.

  • Cisco VPN client 3.5.1 and Cisco ASA 5.2 (2)

    Hello

    I have a strange problem about Cisco VPN client (IPSec) with Cisco ASA. The Cisco ASA runs software version 5.2 (2). The Cisco VPN client version is 3.5.1.

    The problem is the customer able Cisco VPN to authenticate successfully with Cisco ASA, but could not PING to any LAN behind the Cisco ASA. In any case, the problem disappeared when we used the Cisco VPN version 4.6 or 4.8 of the customer. All parameters are exactly the same. What has happened? What is the cause of this problem? How can I solve this problem?

    Please advice.

    Thank you

    Nitass

    I understand your problem, I never used 3.5.1 so I thought that maybe nat - t is not enabled by default as 4.x.

  • The dynamic firewall application on the VPN Clients with ASA

    Hello

    I'll put up a Cisco ASA to complete the remote VPN client connections, but I want to assure you that the dynamic firewall is enabled on the client.

    I know it's possible with the VPN concentrator, but cannot see any documentation detailing that can be performed on an ASA.

    Anyone encountered this?

    Thank you

    James

    I believe you can use Group Policy settings to configure the firewall client.

    You can find more information about this feature in the migration to http://www.cisco.com/en/US/docs/security/asa/asa72/vpn3000_upgrade/upgrade/guide/migrate.htmlguide.

    Hope this helps.

    Andrea.

    Step 1 under Configuration > VPN > General > Group Policy Panel, select group policy in the table and

    Click on change. ASDM displays the Edit Group Policy dialog box.

    Step 2: click on the customer Firewall tab Figure 5-6 shows the firewall client options configured for this example:

  • Access PIX using SSH when connected remotely with VPN client

    Hello

    I think that this should be a fairly simple for someone to sort for me - I'm new to PIX configuration If Yes please excuse my stupidity!

    I changed the config on our PIX to allow only access via SSH (rather than via telnet as it was previously configured)

    Now, everything works fine when I'm in the office - I can connect to the PIX using SSH without any problem.

    However, if I work from home and connect to the office using my VPN client (IPSEC tunnel ends on the PIX firewall itself) I find that I can not connect to the PIX.

    I have configured the PIX to access ssh on the office LAN subnet and the client pool of IP addresses used for VPN connections by using the following commands:

    SSH 172.64.10.0 255.255.255.0 inside

    SSH 192.28.161.0 255.255.255.0 inside

    where the 1st line is reference to the office's LAN, which works very well, and the 2nd line denotes the IP address pool configured on the PIX for VPN access.

    Can someone tell me how to fix this? I have the feeling that its something pressing!

    Thank you

  • Problem setting up vpn l2tp/ipsec

    I tried to configure an ASA5505 with a l2tp/ipsec vpn which I can connect to with Windows Vista vpn client. I had connection problems. When I try to connect, watch windows vpn client tell an error message "error 789: the L2TP connection attempt failed because the security layer detected a processing error during initial negotiations with the remote computer." The newspaper on the SAA is errors saying "Phase 1 failure: incompatibility of the types of attributes of class Group Description: RRs would be: unknown Cfg was: Group 2.

    It seems that the ASA does not like windows vpn client IKE proposal but I do not know if I interpret correctly this error message.

    I was wondering if anyone has seen this problem or have had success with this type of installation. I have the setup of device OK so that I can connect with the Cisco VPN client, but get l2tp/ipsec Setup to work with the windows vpn client turns out to be problematic.

    Can you post the Config of your ASA. Did you check the following link:

  • Cannot connect AnyConnect Secure Mobility Client IPSec 3.0

    Hello

    Our company has a configuration of IPSec VPN on a Cisco ASA 5505.  We previously using the Cisco VPN Client - Version 5.0.07.0410.  Everything worked well with this customer to date.  The problem is it is not supported in our Virtual Machine, and environment with our new version of our networks paravirtualized drivers we get the problems of inadequacy HMAC and not connect to.

    I created a file .pcf with the following information for the 5.0.07.0410 customer:

    Input connection: VC VPN

    Description: no

    Host: xxx.xxx.xxx.xxx (IP address of the Interface of the ASA VPN)

    Authentication group:

    • Name: The name of the Group
    • Password: password for pre-shared Key

    Transport:

    • Activate Transport tunnel
    • IPSec over UDP (NAT/PAT)

    I import the .pcf file in the client, the client connects, you are prompted for AD username - everything has worked well.

    We have currently met that he had to use the Cisco AnyConnect Secure Mobility Client (3.0.0629) - I tried to use the profile for that AnyConnect client editor and I can't not all profile options.  I leave all the defaults preferences (Part1), preferences (Part2), backup servers, matching certificate, Certificate Enrollment and the mobility policy.

    I in the list of servers, click Add.  I enter in the hostname, host (the host name IP address) address and group.  There are no backup servers, I change the main IPSec protocol, save the profile and place it in C:\ProgramData\Cisco\Cisco AnyConnect Secure Mobility Client\Profile (Win7).  Open the AnyConnect Secure Mobility Client and the profile is loaded. Trying to link returns "VPN Agent is unable to establish a connection."  ASA, I don't even see a connection attempts to the outgoing IP address.  On the client, I can ping the ASA and connect with ordinary VPN Client.

    I can't find a place to enter a pre-shared in the profile editor.

    The AnyConnect client seems also not to read the .pcf files.  Am I missing something here?

    My package DART from the failing client is attached.  Any help would be greatly appreciated!

    Kind regards

    Rich,

    AC uses IKEv2 (for IPsec) which is not yet supported on SAA. Support is planned for 8.4 ASA which is still at least a few weeks.

  • Cisco vpn client 5.0.07 no internet access

    I am trying to configure access remote vpn for the ASA 5505 in my office.

    The config is configured on my ASA, and I have cisco vpn client 5.0.07 installed on my laptop (64 bit) to Windows 7.  I can start the vpn, put in my references and it seems that everything goes through, but once I'm connected, I lose access to the internet, and I cannot ping anything (4.2.2.2, 192.168.1.1 (gateway), etc...)

    I keep seeing something uncheck the "use default gateway on remote network", but this option is available in the TCP/IP properties.  Any suggestions?

    Eric,

    This should be the last change. Looks like you don't have inside the network split tunnel.

    Here is the entry you need to do

    TunnelSplit1 list standard access allowed 192.168.1.0 255.255.255.0

    disconnect and reconnect. It should work like a charm.
