WRV200 VPN pass through limits

We use a Cisco Small Business WRV200 to allow guests to our office to access the public internet, regardless of our corporate network environment. We regularly invited several visit of a company and generally these users connect to their company via a local VPN client. I noticed that after about 5 users activate successfully their VPN clients that no one else can connect to any other VPN tunnels. Internet connectivity still works when these 5 tunnels are active, but no other users can create a VPN tunnel after this point. Again, these are all movers or Pass through tunnels behind the WRV200 in one single environment NAT. is there a limit on vpn pass through or leaving behind this device connections and if so can it be changed? I expect a resolution of firmware to this problem, but it seems that it is only a single firmware version for this device. If this unit has an immutable limit, can then someone propose another product, Cisco Small Business wireless which has no limit of transmission?

Thank you...

If the NAT - T is enabled on clients and VPN gateways, there should be no problem. Otherwise, if two IPsec clients behind WRV200 are trying to connect to the same remote gateway without NAT - T active, 2 IPsec sessions could clash between them.

  • Cisco PIX VPN pass through (sorry, tricky!)

    Hello

    I'm having some problems with allowing IPSEC through a Cisco PIX 501. The configuration is the following:

    Does anyone know why it does this? Anyting to my in-house (security level 100) should go directly to my giving and external interface on the net. For some reason, is to treat the isakmp packets differently...

    I have included my config as an attachment, can we see what I missed or have any ideas why it loses the isakmp packets?

    Thanks for any help.

  • Pass through IPSEC on Cisco 857

    Hello people!

    I have gained reciently a Cisco 857 router. I want to do a site-to-site VPN.

    I set up the ATM0.1 with "ip unnumbered" VLAN 1 interface. I have not configured the router to enable NAT or PAT. VLAN 1 is configured with a public Ip of my ISP address. Behind the cisco router, I have a Zywall 5, this device is my VPN gateway. Initially, it works very well with the other soho router but it blocks often, for this reason, I decided to change it for a cisco router.

    My problem now is that the cisco router does not allow the implementation of VPN.

    Need to activate the IPSEC pass-through?, how can I do this?

    Thanks in advance!

    I can't use the MS VPN client to connect to our PPTP server in a remote location. I don't try to use VPN on the router 857, allow just to pass through of my laptop computer behind the router to an external vpn server.

  • Configuration of the router to allow VPN traffic through

    I would like to ask for assistance with a specific configuration to allow VPN traffic through a router from 1721.

    The network configuration is the following:

    Internet - Cisco 1721 - Cisco PIX 506th - LAN

    Remote clients connect from the internet by using the Cisco VPN client. The 1721 should just pass the packets through to the PIX, which is 192.168.0.2. Inside of the interface of the router is 192.168.0.1.

    The pix was originally configured with a public ip address and has been tested to work well to authenticate VPN connections and passing traffic in the local network. Then, the external ip address was changed to 192.168.0.2 and the router behind.

    The 1721 is configured with an ADSL connection, with fall-over automatic for an asynchronous connection. This configuration does not work well, and in the local network, users have normal internet access. I added lists of access for udp, esp and the traffic of the ahp.

    Cisco VPN clients receive an error indicating that the remote control is not responding.

    I have attached the router for reference, and any help would be greatly apreciated.

    Manual.

    Brian

    For VPN clients reach the PIX to complete their VPN the PIX needs to an address that is accessible from the outside where the customers are. When the PIX was a public address was obviously easy for guests to reach the PIX. When you give the PIX one address private, then he must make a translation. And this becomes a problem if the translation is dynamic.

    You have provided a static translation that is what is needed. But you have restricted the TCP 3389. I don't know why you restricted it in this way. What is supposed to happen for ISAKMP and ESP, AHP traffic? How is it to be translated?

    If there is not a static translation for ISAKMP traffic, ESP and AHP so clients don't know how to reach the server. Which brings me to the question of what the address is configured in the client to the server?

  • Apple TV 4 Audio pass through

    Hi-

    My current setup is: 4 AppleTV via HDMI-> Onkyo HT-R990 7.1THX via HDMI-> Samsung Smart TV 60 inch LED. The TV speakers are turned off and that all the sound elements through my 7.1 System.

    My question is about how to disable the audio decoding on the Apple TV. Can the Apple TV 4 simply intercommunication audio without decoding? That's why my receiver will decode and choose the best audio configuration for content.

    Having a transmission option is fairly common on most devices such as Blu - Ray players. What's not an option on the Apple TV? I know by selecting "Auto" on the Apple TV, it will send the PCM signal. Why would I have DD or PCM if the content is DTS Master for example? It makes no sense to me.

    I think I have a 'Pass-through' option would satisfy loyal people optical cable and move is a real audio visual component of the Apple TV.

    Does anyone know how this can be done? Your help is greatly appreciated. See you soon!

    It can normally send PCM for music/video stereo and support the bitstream DD for 5.1, ATV 4 7.1 - I assumed AppleTV 4 this but have moved for a few months and don't have not connected my AV Pioneer amp just for the Samsung TV.

    AppleTV does not support DTS officially, certainly not for the content of the iTunes store is not an option, but I don't know about 3rd party applications that could broadcast "other videos" of local shares.

  • using PostDelayedCall how to get the value passed through void * callbackData?

    Can someone tell me how to get the data passed through void * callbackData?

    The following code, panel_ptr has the right address but still contains zero.

    void CVICALLBACK value_changed (void * callbackData)
    {
    int * panel_ptr;
     
    panel_ptr = callbackData;
    calculate_new_value (* panel_ptr);
    }

    int sign;

    Panel = 2;

    PostDelayedCall (value_changed & Panel, 0.2);

    The problem is using the callbackData parameter if it is a pointer, it must be a pointer to something which is still topical at the moment that the callback executes. That is to say, you cannot pass the pointer to a local variable in callbackData as when the callback executes the pointer is no longer valid. You can switch from its value, instead, in this way:

    ... SomeFunction)

    {

    int sign;

    ...

    Panel = 2;

    PostDelayedCall (value_changed, (void *) Panel, 0.2);

    ...

    }

    void CVICALLBACK value_changed (void * callbackData)
    {
    int panel_ptr;
     
    panel_ptr = (int) callbackData;

    calculate_new_value (panel_ptr);

    return;
    }

    There are many discussions on the forums on callbackData parameter that you might want to read.

  • Card reader chip as a pass through for VMware View 5.1 device (NOT USED for AUTHENTICATION)

    I try to get a USB Smart Card Reader * to work on related under VMware View 5.1 clones

    * not as an authentication device, just like a transmission of smart card reader

    Not tried:

    1 activated pass through card reader in the registry for the VMware view client

    2. active "allow redirection of card reader" in the policy active directory

    3. customer connected to view, selected USB drive list, connected to the customer

    After that, the card reader will appear with a "generic smart card", but it does not actually work.

    We executed the diagnosis of the smart card and he pointed out that the drivers are ok and windows service is ok, but the map can not be found.

    PS: When we tried first, about 2 weeks ago it worked, but it has suddenly stopped working. (Needless to say that the virtual machines and the Clients were restarted several times).

    Check that you have not installed the "PCoIP smart card Redirection" option during the installation of the agent. If it is present, it will redirect calls made RDP client smart card. Because you use a 'local' to the desktop USB drive, you don't want to do.

  • RVS4000 to WRV200 VPN through DSL

    I tried to set this up and not get the same error message - no corresponding tunnel on the remote side.  I have a wrv200 at home and a RVS4000 to work and I'm trying to set up a tunnel VPN from home to work.  The two are connected DSL.  Any help in getting this set up would be great, I worked at it for some time without success.  Thanks in advance for any help/light you can throw on this problem.  FYI, I installed the same VPN on both routers by using the same key preshared and such.  ???

    Thank you - Ed

    Ed,

    You can post your each router configurations?  The configuration on each router must be unique within the environment of routers.  If you post the configs, we can verify that they are configured correctly.  Change public IP address if you are concerned about the announcement of your IP address here.  Thank you.

    My question is "we will get this configuration by using the graphical user interface for someone who is not notified about the command line?"

    Thank you

    Of course, all this can be configured via ASDM.

    Looking at the second example you posted above, they point you first change:

    ACL split of the tunnel for the AnyConnect customer

    This Configuration > remote access VPN > network (Client) access > AnyConnect connection profile > (chose the profile and select Edit) > (choose "Manage" next to group policy) > Edit > advanced > Split Tunneling > ensure that the policy does not "Inherit" but rather "Tunnel network list below" > Unselect "Inherit" next to the network list, then 'manage '. Enter your networks you want in the GUI in this dialog box. Click OK all the way back to the main window ASDM and click on apply.

    You then change:

    Crypto ACL for the tunnel from Site to Site

    To do this, go to Configuration > VPN Site-to_site > connection profiles > (choose your profile and select edit) > add the VPN client address pool to the list of local network between protect networks. Yet once, click OK all the way back to the main window ASDM and click on apply.

    Then, allow the

    ASA to redirect back on the same interface traffic it receives

    .. is defined under Configuration > Device Setup > Interfaces. (check the box at the bottom of this screen). Click on apply

    Finally, there is the NAT exemption. For which go to Configuration > firewall > rules NAT. Add a NAT device rule before rules network object with Interface Source out, Source address your address pool VPN, the Destination address to include remote subnets and Action is Static Source NAT type source address and destination address remaining as original (i.e. without NAT). Once on OK all the way back to the main window ASDM and click on apply. Save and test.

    Good luck. Don't forget to note the brand and posts useful when your question is answered.
