solution VPN Neu, DMVPN
Hello world
I'm doing my research about to create new connections between offices in our network.
My plan is to have with the centres and the rest as the rays.
There are 35 offices, 12 of which are up to 20 users.
most of the offices are between 20-200 users
and only 2 are more than 200 users
DMVPN is sure how, but I have a request for short.
What kind of models do you recommend?
for example, for small offices I think to the Cisco881-Sec-K9
For hubs, I was thinking about the Cisco 4451 x, how do you think?
Thanks in advance,
Thomas
Here is a comparison between the 4000 series routers. I think I'd go for the cheapest 4431. If money is no object to stick with the 4451.
Make sure you get a HSEC license as well, otherwise flow crypto is severely limited. I also get the AppX license.
For the rays, if it were my money, I would like to have the 890 series routers. They can dish line a circuit of 100 Mbps and come with 'Advanced IP', so that can run BGP, EIGRP, etc.. Almost no restrictions. A Cisco 897VA is particularly versatile. Note If you want the grid, you can order a support separately for the 890 series mount rack mount routers. The 897 a ADSL, VDSL and port WAN Gigabit copper/fiber built in. It can plug into a lot of WAN circuits as a result.

Best design solution VPN for Central/branches
Hi all
I would like your comments on the design of a VPN account solution required the following:
Right now, the customer has a single office. I will be putting in place of a Cisco 1811w for them, and its main functions will be wireless, firewall with CBAC and EZVPN server access.
Server EZVPN function will be carried out so that employees with laptops can work from home.
In the near future, there will be about 4 branches in operation.
Static IP address is available for the main office, but I'm not sure if the static IP will be available for the office once they are established (there are 50 / 50 chance).
There will be an Active Directory server in the central location and will be accessible from the branches.
My question is - given the uncertainty in the branches having a static IP - what is the best way to implement the VPN to connect them to the branch?
Each branch will have an installed Cisco 831.
Is EZVPN a viable, given the above requirements?
Is it possible to put in place the 831 as customers without XAUTH EZVPN, all keeping XAUTH for employees using EZVPN clients?
If this does not work, XAUTH might have to.
Or, given the situation, you would opt for DMVPN... Unfortunately I do not know too much about it as the technology for now... What are the advantages / disadvantages of its use, if it is an appropriate solution to this scenario?
Thank you all in advance for your comments!
Sean
I think that you need to use a mode of expansion of network (configured in the vpngroup) instead of client mode. Just make sure that each office uses a different and not overlapping address space.

I am in the initial phase of research DMVPN. We currently have an MPLS network running BGP. Each site has Internet at home as well as a VPN site-to-site is built on the router and talks to an ASA when the SPLM fails.
I want to implement DMVPN to do away with the site to site VPN and ASA. I'm going to run EIGRP on routers to connect DMVPN. Are there any good whitepapers on BGP as the main path and by EIGRP on the DMVPN as a backup? Or no focus on a general config?
Thank you
It's really the main issue.
With your configuration DMVPN roads will be internal EIGRP of an advertisement of 90, so your default DC prefer DMVPN on MPLS, which is exactly what you don't want.
There are several ways around this as summarizing through DMPVN, redistribution connected on the sites of the branch in EIGRP so roads DMVPN are external as well and then changing measures etc.
The other alternative I have ever done so it's for your information is really Cisco have what is called a solution IWAN where DMVPN is performed everywhere that is, even through the MPLS network.
That would solve your problem of external routes internal EIGRP but IWAN vs is much more than just that, even if you do not need necessarily to implement the entire solution at a time.
I just thought that it should be mentioned, and if you want more information on this I can direct you to the design guide.

DMVPN spoke of issues after migration double ISR2 3925 hub to ASR-1001 X
Hello world
After our hub solution migration DMVPN double ISR2 3925 to ASR - 1001 X (running asr1001x - universalk9.03.12.03.S.154 - 2.S3 - std.SPA.bin) we started to have some problems with tunnels rays beat (which goes up and down) and sometimes never came.
Running 'show dmvpn' speak it is stuck in State PNDH to our hub. To solve the problem, we run 'stop' and then 'non-stop' on the tunnel interface to actually speak that DMVPN Monte. Also runs "clear encryption session
" on the shelf often solves the problem. So, it seems that the question has something to do with IPSEC. When the problem occurred, and then debug crypto ipsec, crypto, crypto isakmp and crypto engine socket the following can be seen on the hub:

Very weird. Also, in looking at att the hub debugging messages it seems that Cryptography is associated with evil Tu3300 tunnel interface when it is Tu2010. Normal or Bug?

ASA IOS would only you are using a "NAT 0" at a time, how do you get around that.
TIA
nonatdmz list of allowed ip extended access any 192.168.100.0 255.255.255.0

DMVPN/GETVPN double spoke router Design
All the:
I'm developing a new design of VPN - cloud DMVPN, routers double hub to the main site, router hub unique to the backup site and double routers spoke at the Directorate General/remotes.
This is all via internet transport, with overlay GETVPN to encrypt.
Somebody has experiences establishing DMVPN designs with dual spoke routers, and how go you about it? HSRP @ interface outside or inside, determination of Protocol routing only, etc...
Thanks in advance!
Hi Steve,.
Using BGP will complicate things a bit.
This is because you must announce the IP (used as source GRE) HSRP on both your ISP. If you need to own that IP.
If this is not possible, you can use the double Hub - double DMVPN Layout (a part of the link DMVPN I joined precedent).
This will require a WILL by the router and routing to use routing protocol.
HSRP can still be used on the inside of the interface, the GRE tunnel status tracking.
Doesnít of traffic must be translated as possible via GRE tunnels.
Please rate if this helped.
Kind regards

Hello
It looks like one of our customers were buying SRI is to connect to the Microsoft via DMVPN cloud azure, because Cisco ASA does not (yet) support.
ASA will support this in a future release nearby?
Finally, anyone have any suggestions? (Apart from not using azure ;-)
Based on the comments of the representatives of Cisco in sessions DMVPN/FlexVPN to Cisco Live!, there is no plan to support DMVPN/FlexVPN on SAA. This may have changed since then, but I doubt it.
VPN infrastructure evolve slowly but surely based simply on strategies IPSec VPN that supports the ASA to the more modern and more flexible based on the VPN as DMVPN and FlexVPN road. The key here sentence is "road", which puts the technology firmly within the scope of routers rather than safety devices.
The ASA units are very good in what they do, but modern VPN infrastructure are a bit beyond their reach.

VPN in 1921 with the AAS wireless card
I have a router Cisco 1921 with a Verizon LTE eHWIC wireless card. I want this device to use dial-on-demand routing (which will be always activated) to connect to the wireless network and then open a VPN IPSec tunnel in a central location. The tunnel ends in an ASA 5545
Looking at the documentation, I see examples of use (DMVPN and EasyVPN
( http://www.cisco.com/en/US/products/ps5949/products_installation_and_configuration_guides_list.html)
But these methods are not supported by the ASA.
So my question (s)
1. can I use a point to point standard IPSec VPN without DMVPN tunnel, etc. ? Where I go to see an example (the above does not seem to have one)
2. If the wireless interface retrieves an address FRO Verizon (similar to DHCP), how can I specify the peer side of the ASA?
The simplest is to configure EasyVPN which is supported on the SAA. There you have the same setup as for the Legacy Client VPN. Another option is to set up a traditional crypto map on the router and that link to the group by default-tunnel on the SAA. For both styles of VPN - you need not to know the address of peers as it is always considered as dynamic.

I'm standing, a site with an L2L connection, but needs to vpn client host connections as well. I know that you can do with old good crypto cards, but it is not the preferred method these days with the virtual Tunnel Interfaces? Trying to figure out the best method to deal with. Links and guidance appreciated.
Hi Robert,.
To be honest, today the best recommendation is to run AnyConnect instead of the legacy IPsec client.
In the case where you would need to run the IPsec client, it doesn't really matter if you use a virtual interface or not, given that from the point of view of the VPN client functionalilty is the same.
I would recommend simple card crypto for a simple connection to a router not to treat many types of VPN as DMVPN, VTI, DVTI connections, etc.
However, if you want to get more familiar with DVTI, then I suggest this link:
Cisco Easy VPN with IPSec configuration dynamic Tunnel Virtual Interface (DVTI)
Remember that the configuration of a box of equipment or software is pretty much the same thing on the VPN server.
With a card encryption:
So as you can see the configuration of the client is the same on the server:
crypto isakmp client configuration group vpngroup key cisco123 dns 10.10.10.10 wins 10.10.10.20 domain cisco.com pool ippool acl 101
What really changes is to use if a card encryption or a VTI.
It will be useful.
Portu.

I can't connect to the work computer via remote desktop. Error, said that this computer can not connect.
Check with your work IT people to see if they allow to connect to desktop computers. If they do, they will be able to tell you how. In general, companies do not allow that without a solution VPN in place. Brian Tillman [MVP-Outlook]

How can I get the engine working in the ASA 5505 Crypto
I bought a brand new ASA 5505 to connect to the Cisco 3640 and I can not yet set up the tunnel. I have tried to change the set of transformation to just but know luck. I recently put a VPN using DMVPN and Cisco 501 in a site-to-site, but it has been wondering what happens.
The router (3640 executes code 12.4) seems ok and I don't think I have a problem with the router with Cisco 501 great work.
This is a laboratory environment.
This is the function defined on the ASA 5505
The devices allowed for this platform:
The maximum physical Interfaces: 8
VLAN: 3, restricted DMZ
Internal guests: 10
Failover: disabled
VPN - A: enabled
VPN-3DES-AES: enabled
Peer VPN: 10
WebVPN peers: 2
Double ISP: disabled
Junction ports VLAN: 0
AnyConnect for Mobile: disabled
AnyConnect for Linksys phone: disabled
Assessment of Advanced endpoint: disabled
This platform includes a basic license.
This is a ping from 10.3.4.10 to 10.1.1.1. He said nothing about IPSEC or ISAKMP.
That's what I get when I do the: show crypto ipsec his
ASA5505 (config) # show crypto ipsec his
There is no ipsec security associations
ASA5505 (config) # show crypto isakmp his
There is no isakmp sas
Debug crypto isakmp 10
entry packets within the icmp 10.3.4.10 8 0 10.1.1.1 detail
I have worked on it for a week and don't really know if I have a bad ASA5505. Since the normal stuff like browsing the Internet works and I can ping to the outside and inside, I don't know what to think. See attachments.
"Do what you asked has worked.
Nice to hear that your problem is solved.
"My question is can I use the transform-set ESP-3DES-SHA instead of MD5?"
Of course you can.
Kind regards.

IPSec Site to Site VPN Solution needed?
Hi all
I need a solution to provide full connectivity to one of my clients. I created two IPSEC Site to Site VPN, one between the INFO and RITA and second between NIDA and RITA. I can access RITA machine that is 172.16.36.101 at the INFO and 10.0.0.5 to NIDA.
Now, I need to give access to my customer INFORMATION to direct NIDA 10.0.0.5 without established VPN machine to NIDA 10.0.0.5 of 172.16.36.101 access.
Could you please give me the solution how is that possible?
Concerning
Uzair Hussain
Hi uzair.infotech,
Looks like you need to set up a grouping between the 3 sites, at the end of that your topology will look like this:
INFO - RITA - NIDA
You can check this guide that explains step by step how to configure grouping:

Hope this info helps!

DMVPN (NAT?) solution with rais as subnets
Hi all
I have a large number of remote networks that are prevalent all over the world. Currently, they are all individual island with no connectivity to anywhere else.
What I would do is connect all back to Headquarters on the internet so I can access it remotely. The internet service that I receive from all the sites will be different and unknown for example some directly on the internet, some behind NAT.
So I think that the solution to this is DMVPN.
But my problem is that all of the remote locations have the same internal subnet. So, how can I make sure that they are all connected and remote devices are all available at the same time?
I wonder if I can configure NAT on the router may talk so that each device has a static nat with the Natted IP is unique. I labbed this place GNS3 and it seems to work. However the problem is that there are hundreds of devices on each site, which means a large number of NAT entries.
I was wondering is it possible to make a fair full 1:1 Nat specifies a network to network. For example, something like 192.168.20.0/24 NAT to 10.0.1.0/24, so try to access the 192.168.20.5 in fact, it connects to 10.0.1.5
Has anyone never has something like this work?
Y at - it a good solution?
Thank you, Simon
It is possible, but (assuming they already use NAT for Internet access) you'll need to define things very carefully to avoid interference with what they have.
Do a complete translation of subnet is easy and is a good word:
IP nat inside source static 10.0.0.0 network 192.168.0.0/24
The problem is that this will replace all existing for this subnet NAT, condition and the existing NAT configuration.
Can you provide an example of how the current NAT is set up for one of these sites?

Some client has a main office and several branch offices connected via VPN.
He needs a solution that will allow him to specific information and monitor VPN sessions (ex: number of sessions, session source, date, duration, bandwidth used, ect,.,)
Cisco provides such a solution.
a solution that is better with GUI
Please, your quick response time is appreciated
Included with Cisco Security Manager is an application called performance monitor, which supports the monitoring of remote access and site-to-site VPN. links:
Security Manager:

Performance Monitor user guide:
http://www.Cisco.com/en/us/products/ps6498/products_user_guide_book09186a00806b7a60.html
Performance monitor is from the previous security management product called CiscoWorks VMS and is currently no improvement. We want to implement an update of health related to security and performance monitoring capacity on-par with the Security Manager, but not clear word yet.
Security Manager and performance monitor can be downloaded and used up to 90 days of assessment.

DMVPN Solution for 50 Branches...
Hi all
We have about 40 branches and a Central data center.
each office is connected with the domain controller and all internet traffic passed and filtered between DC and the Central firewall.
We have VoiP, with a Central in DC call manager.
our data are in DC, except some of the offices that have their own file server.
RDP is also continue to use.Now, one day, we have a MPLS network linking all of our offices.
I do a search about to implement a DMVPN for all, or as a second solution to some of our offices (the small one).
How can you recommend or kind one or the other solution?as I read, the voice traffic is the most critical and the most difficult to manage with the ISP and DMVPN Solution.
I would really apriciate your opinion.
Kind regards
Thomas.PS
I chose cause DMVPN we have in the near future to have a backup of our DC in a second office, only for some of the critics of the data and services.
That's why I think to use the DMVPN with 2 HubsYes you can run it on the Internet. Yes, you may have questions of VoIP.
A solution that we used in the past is double internet connections. You dedicate one VoIP and one for everything else. Always much cheaper than MPLS.
You can also use Pfr (routing performance) to select the circuit to use based on the latency and jitter, and the type of traffic.
