    Cisco VPN Client Problem

    Locked

    by ace79424 ·

    Hello!

    The office uses a Cisco 5510 and remote users from home VPN using Cisco VPN Client 5.0.01.0600. Here is the problem. Some users can establish a VPN connection but cannot access the network at all. No network drives, Outlook, or anything in the network. Other users use the Cisco VPN Client and get connected and can access the network just fine. We also have a Microsoft Windows VPN connection that we were using before we installed the Cisco VPN Client and all users can use the MS Windows VPN connection just fine with accessing the network. The users that can connect with the Cisco VPN Client but still cannot access any of the network live all over the United States. The only common denominator in these users is that they all have DSL through AT&T. The users that use a cable modem or DSL that is not AT&T can use the Cisco VPN Client without a hitch.

    To sum up:
    **All remote users can establish an MS Windows VPN Connection and can access the network.
    **All remote users can establish a secure connection through the Cisco VPN Connection.
    **Most remote users can access the network through that connection.
    **Only a handful cannot access any of the network after connection the VPN with an error message of “Cannot Find Path”

    Opened to any and all suggestions!! Is it a Cisco thing or could it be a ISP thing.

    Please help!

      You should always uninstall or disable software that will do the same thing. Cisco is always updating software. Be sure you update computers/laptops to the new software.

      Same Issue

      I have about 10 clients using the Cisco VPN software. One person is having an issue. They brought their laptop into the office and we used a seperate connection to come back in on our main connection. It works just fine. However when they go home they establish a connection but they can’t ping anything no DNS nothing. I can’t ping them either but I can ping others that are connecting through VPN. In the server logs I see the connection, no errors are reported. I gave them a differenct laptop that others have used to connect in with but this also does not work.

        Network range conflict

        by wdewey ·

        In reply to Same Issue

        If the network range behind the VPN is the same as the one that is being connected from than this could be your problem. The most common private ip address range is 192.168.0.0 255.255.255.0 so if this is the address range of the business network then VPN connections will be problematic. It will be necessary to change the address range of the business network to get consistent VPN connections from most locations.

      Same issue. Narrowed down.

      I have a simular issue that involves AT&T Communications Manger for teathering a blackberry. Once I installed this software the user was able to make a remote connnection using cisco vpn but unable to access and remote resources. When I uninstalled the software everything worked fine again. But now she cannot use her teathering feature on her blackberry.

      In this case ATT seems to be the issue. I called them a few months back when they were switching from Cingular back to ATT and they told me they did not support this software???? I noticed in your post you were dealing with ATT DSL and was wondering if they make you install any software to use that service?

        I am seeing the very same issue. Users from some sites get logged on with Cisco VPN but can not ping anything. Has anyone came up with anything on this issue?

          IPSec limitation…and alternative…

          by mstewart ·

          In reply to SAME ISSUE

          I believe this is a limitation of the quantity of IPSec tunnels and is the reason why VPN has moved onto other options… SSL.

          When connecting from Home DSL service, the VPN would connect, and depending on the time of day… the VPN Tunnel works fine. After upgrading the DSL service to Business class DSL, then the problem goes away. Same with Cable Broadband…

          I have moved on to using the SSL VPN Client which works much better, like 100% of the time.

          Locate your .pcf file and edit it. Add the following line at the bottom:
          ForceNATT=1
          Save it and try again. It should work now.

        • #2906649

          ForceNATT=1 doesn’t seem to work either…

          ForceNATT=1 doesn’t solve the problem. Still
          appears to be an issue. Anyone else have luck with this?
          Same problem.
          My client has AT&T PPPoE service DSL 2wire modem. Cisco client works fine everywhere else.
          At his home Cisco client connects but no resources on corporate network can be accessed. Even pings to machines which usually give a ping reply don’t respond. We can verify traffic get’s to the local network but seems to be dropped at the AT&T equipment on return.

      Fix – Worked for me

      by lgilliam ·

      In reply to Cisco VPN Client Problem

      I had this same issue. When reading through my .pcf file, I noticed the field:

      “ISPConnect=BlackBerry Modem”

      For some reason Cisco was remembering the last time I used VPN with my BlackBerry, and refused to allow traffic when connected to AT&T.

      I cleared that field (“ISPConnect=”), saved the file, reconnected to Cisco VPN, and it worked.

      I would say send the users a new .pcf file and have them import it via the Cisco client.
