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!

Intercept-dhcp works to tunnel L2TP through IPsec ASA?

Hello

Is there anyone in the world operating a tunnel L2TP through IPsec on Cisco ASA for the native Windows clients and a Tunnel Split Configuration fully functional?

I created a tunnel L2TP through IPsec on the ASA 5520 9.1 (6) Version of the software running. My configuration is:

However, real communication takes place above the tunnel if I 'Gateway on remote network use default'. If I disable this option among the preferences of the IPv4 of the virtual interface of VPN in Control Panel as described in the section 'Configuration of Tunnel of Split' of This DOCUMENT then Windows sends all packets through the channel, because it fails to extract from the ASA routing table. Split routing works perfectly when using legacy Cisco VPN Client with the same group policy, but does not work with L2TP over IPsec.

As far as I can see, the 'intercept-dhcp' option is inefficient somehow. I even managed to intercept packets of the PPP virtual machine Windows XP interface, and I saw that windows sends its DHCP INFORM requests, but the ASA does not. My question is why?

-J' made a mistake in the above configuration?

-Can there be one option somewhere else in my config running that defuses intercept-dhcp?

- Or is there a software bug in my version of firmware ASA? (BTW, I tried with several versions of different software without success?

Hi, I have the same problem you have, but I was lucky enough to be able to install version 9.2 (4) on which this feature works very well. I'm suspecting that it is a bug, but I need to dig a little deeper. If I find something interesting I'll share it here.

VPN - SRP527W <>Cisco 857 established but no tx fraffic side SRP

I have now established between SRP527w and cisco 857 ACE, but if I ping from a multitude of Cisco to a host on the side of the PRS I get only rx traffic in the tunnel, the stats keep tx 0 and ping is not answered.

My tunnel is to send a voice call in IPSEC tunnel keeping DSCP bits, it communicates vlan voice SRP with Cisco lan.

I have the SRP 2 VLAN:

1 vlan for data on ports 1, 2, and 4

1 voice vlan ports 1,2,3,4.

I connect a netbook to port 3 and I can connect to the internet, but I can't reach by ping across the tunnel

Perhaps the traffic of the vlan is voice natted with the ip address of data vlan?

I need all traffic must go through the tunnel without being natted on the cisco side I have a policy to avoid the nat but don't know if SRP have no problem about it too.

All gateways are ok

Any idea greatly appreciated, thank you very much

Hi, manual,.

The RPS not NAT via the tunnel, which shouldn't be a problem.

You try to ping a client in the remote subnet, or IP address to the VLAN RPS at the other end of the tunnel? (Could you try both please?)

See you soon

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.

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.

Configuration of VMware ESX 5.1/5.5 pass through for PowerEdge 2970

Hello

I tried to configure VMware ESX 5.1/5.5 pass through for a 8 GB Qlogic FC HBA on PowerEdge 2970 server.

Even after activation of the virtual technology in the BIOS, the PCI device is not listed in "Advanced settings" to configure pass-through. Attached screenshot shows the current setting of the processor.

Y at - it all the additional steps required to configure it.

Concerning

E.

Hello Sara

You're talking Direct path IO or single root i/o virtualization? If so, none of these features are supported on the 2970 system.

I don't think that or the other of these characteristics were available until our 11 generation systems.

Thank you

I'm losing configuration when I turned off my Cisco 857 router

I bought the new router Cisco 857 of the shop. Router must have been used before as I couln can't go inside with name of user and password default cisco/cisco.

Well I followed digital and reset the password for the user name and password. Now I have finally connected to Cisco CP express on my IE browser.

I discovered that someone was using a router in the shop that's why I countries: ' t log in to him in the first place. In any case the problem is that when I changed my configuration and applies the settings he remembers until I turned off. When I turn on again he remembers all the parameters of this shop.

He returned everything back: IP address, former account to level 15 and password - just like after the password reset.

I tried again and he again lost the settings. So I found instructions:

http://www.Cisco.com/en/us/products/HW/routers/ps233/products_tech_note09186a00800a65a5.shtml

I followed it and changed once again all the settings of the router. My settings are still lost after the power on/off. I noticed that when I do everything first bit it shows

0x2102 not 0x2142 like they think that is password reset mode.
