Cisco Vpn Client And Firewall 2011

in Firewall

I posted the problem a while ago (under Total Security 2010) and no solution ever worked. I learned to live with this headache, but I just reformatted my laptop, install Total Sec 2011 and hope it would work now. Nothing.


I am posting the original problem because the behavior is exactly the same:


---------------------------------------------------------------


My configuration of the programs involved is as follows:


Windows 7 Professional


Cisco VPN Client 5.0.07.0290


BitDefender Total Security 2011


RealVNC Enterprise 4.5.1


- I connect from my home (192.168.1.101) to my office using Cisco VPN Client 5.0.07.0290 and that works fine. When the Cisco VPN Client connects, I get assigned a fixed IP: 192.168.25.118. There is a rule in the office firewall that only permits my connection using ports 5900 and 5800 (the ones used by RealVNC) to my desktop (10.12.0.103).


- The new network (192.168.25.0) is detected by Bitdefender and I set both networks (my internet home connection and the new office network) as FULL TRUST.


- Whenever I click the existing VNC connection the program says:


"Attempting to connect to host..."


After 20-30 seconds or so, it says:


"failed to connect: Connection timeout (10060)"


- I tried adding rules, resetting rules and adding them again, with no luck.


- So far the only way I can make everything work is completely disabling the bitdefender firewall.


CONCLUSION:


There is something wrong with the bitdefender firewall, that even having all programs involved and all IP's involved as ALLOW on any port, the VNC connection still gets blocked.


ADDITIONAL INFORMATION:


- If I completely disable the bitdefender firewall, run the Cisco VPN (connects fine) and then run RealVNC: IT WORKS FINE.


- If I enable the bitdefender firewall, run the Cisco VPN (connects fine) and then run RealVNC: IT DOES NOT CONNECT.


- If I completely disable the bitdefender firewall, run the Cisco VPN (connects fine) and then run RealVNC: IT WORKS FINE. And after that, if I reenable the firewall, after 2-3 seconds the connected session freezes completely.


If you need any additional information, please let me know.


Waiting for an answer,

    Hello,


    Please try to add the above mentioned IPs: 192.168.25.118 and 192.168.25.0 to the list of trusted IPs under the Firewall -> Network tab. Then, having the Firewall enabled test and see if the issue still occur.


    Also please check the following registry entry and tell me the start value of the key below:


    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip


    The Start entry should be 0 (zero). If you have it set to 1 please manually edit the entry then restart the PC and test again to see if the issue will still occur.


    Kind regards,

    Hi Dany,


    I added the 192.168.25.0, the .118 was already there and the registry value was already at 0.


    I also tried changing the Local Area Connection 2 to VPN (because it is).


    The issue persists.

    Hello,


    Where is the VPN connection listed ? I do not see it in the screenshot.

  • rpareja

    One of the columns of Local Area Connection 2 (that is showing as NO), I already tried setting it to YES.


    And the Network Zones on bottom, the rows are the one for the Local Area Connection 2 (the screenshot is for you to see all lines added as TRUSTED).

    What happens when you try to set the VPN connection under Network to YES ?

    Nothing noticeable, and the issue is still present.

    Hi,


    we have also this problem on a Windows 7 x64 computer with BitDefender Internet Security 2011 and Cisco VPN Client 5.0.07.0290 (x64).


    Disabling the BitDefender Firewall and we can connect through the VPN tunnel to a server using mstsc.exe. But if the firewall is enabled, the mstsc connection timed out. Also a ping is not possible. But the VPN client connects without an error. The firewall can be turned off while the VPN client has already connected and then a remote session is possible. But turning the FW on again, the remote desktop session get lost.


    The Avira Premium Security Suite does not have this problem.


    Also running Windows 7 x32 and BDIS 2011 works.


    Is any help available?


    Regards, Nils.

    Hello:


    The issue is the same for me "Cisco VPN 5.0.07.0290" and "Windows 7 Pro 64 bit" and "BitDefender Total Security 2010 64bit


    (latest updates as of this writing). I just started using VPN so this just started for me.


    The cisco cvpnd is fully allowed (etc.).


    Has this been resolved?

    Hello there,


    I just purchased Bitdefender 2011 this week and installed the same configuration as described above on 2 new machines (a Desktop and a Laptop). Both of these machines run Windows 7 64-bit (Desktop - pro; Laptop - home) and both machines are running Cisco's VPN Client 5.0.07.0290 for 64-bit. I have the exact same problems as noted by all of the previous posters and only discovered the problem after an hour-and-a-half conference call with my IT guy and a Cisco Support representative last night. Honestly, I wish I had know before purchasing that this was an issue as I work at home every day and rely upon my VPN connection. It appears from a post in February that a fix is in the works. Can someone please provide an estimated time frame for the release of this fix? Obviously, I am concerned as this issue has persisted since at least October of last year. Any help or insight would be appreciated. Otherwise, I will have to go purchase an alternative program. Thanks.

    Hi,


    I'm having the exact same problem. On Windows 7 x64 using Cisco VPN Client 5.0.07.0290 x64 (and BitDefender Internet Security 2011 with latest updates), the client connects to the network, but I can't access anything. It works ok with firewall disabled. The vpn adapter is set as Trusted, vpn=yes, stealth=no.


    Is there any solution?


    Thanks.
