• With a dynamic IP address DMVPN spoke

  A DMVPN Hub-and-Spoke scenario. Hub is in HQ Corporate whileSpokes are based on Internet only. No idea how I could establish peering relationship if the rays are assigned dynamic IP address? He should learn via PNDH?

  I wonder how Zero Touch (ZTD) deployment point in the documentation for the rays...

  Hello Gerard,.

  While the CENTER should have a static IP address, speak it may have a dynamic IP, this isn't a problem.

  The hub is called a NHS (the next hop server). Basically, when the RADIUS will bring up the tunnel, he is recorded to the NHS via PNDH, so the hub will be a dynamic mapping of public IPs private rays.

  The only thing is that you must manually set the address IP of NHS at the rays so that they can register.

  Hope this helps.

• Dynamic IP address of the remote VPN L2L ASA sites

  Hello

  I have a client who is to change their links to backup from ADSL to 4 G - LTE using Cisco 819 s.

  Unfortunately, access to 4G of PSI will have dynamic IP addressing. Online, I see configurations for one remote site with dynamic IP address, speaking to ASA, but I can't find anything on several sites of L2L linking to the ASA with dynamic addressing.

  Does anyone can help with examples of configuration

  Hi Richard,

  the next days I will also write a blogpost with triple recovery WAN by using this configuration.

• L2l between an ASA 5505 and WatchGuard XTM330 with dynamic IP

  Hi guys,.

  I looked for a solution on this one but can't find inappropriate, most of the discussions were old and with dead links to the solution.

  We have an ASA 5505 with static IP address on the outside and a customer who have a WatchGuard XTM330 with dynamic IP address to the outside.

  Is it possible to have an L2L VPN between our ASA and the WatchGuard when he has a dynamic IP?

  I have no experience on the series of WatchGuard,

  so, I am very grateful for any answer!

  Thanks in advance and have a nice day

• VPN tunnel with IP dynamic

  Question:

  Is it possible to install a GRE tunnel between two routers, one that has a dynamic IP, the other has a static IP address. If this isn't the case, GRE, is there another tunneling protocol we could use?

  In the search for setting up a VPN, I found that the way suggested to do is a GRE tunnel, so that dynamic routing work via VPN. We do not use dynamic routing, but I want the flexible design for future changes that will occur.

  Our facility is:

  2651XM (hub) to the corporate office (static IP). DS-1

  827H (spokes) to each branch (dynamic IP via DHCP). ADSL.

  IOS version 12.2 (13) T supports Multipoint GRE function which will allow your GRE tunnel on the side of ADSL to use a dynamic IP address. Locate the CCO love and documentation DMVPN (dynamic multipoint VPN).

  Hello guys,.

  I have Cisco ASA5520 facing the ISP with private IP address. We don't have a router and how to get the IPSec VPN through the internet?

  The question statement not the interface pointing to ISP isn't IP address private and inside as well.

  Firewall configuration:

  Firewall outside interface Gi0 10.0.1.2 > ISP 10.0.1.1 with security-level 0

  Firewall inside the interface Ethernet0 192.168.1.1 > LAN switch 192.168.1.2 with security-level 100

  I have public IP block 199.9.9.1/28

  How can I use the public IP address to create the IPSec VPN tunnel between two sites across the internet?

  can I assign a public IP address on the Gig1 inside the interface with the security level of 100 and how to apply inside to carry on this interface?

  If I configure > firewall inside of the item in gi1 interface ip address 199.9.9.1/28 with security-level 100. How to make a safe lane VPN through this interface on the internet?

  I'm used to the public IP address allocation to the interface outside of the firewall and private inside the interface IP address.

  Please help with configuration examples and advise.

  Thank you

  Eric

  Unfortunately, you can only complete the VPN connection on the interface the VPN connection source, in your case the external interface.

  3 options:

  (1) connect a router in front of the ASA and assign your public ip address to the ASA outside interface.

  OR /.

  (2) If your ISP can perform static translation of 1 to 1, then you can always finish the VPN on the external interface and ask your provider what is the static ip address assigned to your ASA out of the IP (10.0.1.2) - this will launch the VPN of bidirectionally

  OR /.

  (3) If your ISP performs PAT (dynamic NAT), then you can only start the tunnel VPN on the side of the ASA and the other end of the tunnel must be configured to allow VPN LAN-to-LAN dynamics.

• VPN client and peer simultaneously with dynamic ip

  LAN (static ip) - to - Lan (static ip) is very well

  LAN (static ip) - to - Lan(static ip) + VPN Client is fine

  LAN (static ip) - to - Lan (dynamic ip) is very well

  LAN (static ip) - to - Client VPN is good

  LAN (static ip) - to - Lan(dynamic ip) + VPN Client does not work

  I think that the problem is due to this commans

  ISAKMP crypto keyname key address 0.0.0.0 0.0.0.0

  or

  ISAKMP crypto keyname key address 0.0.0.0 0.0.0.0 no.-xauth

  How can I distinguish a router with a dynamic ip address that doesn't require authentication from a VPN Client that requires authentication?

  P.D. I use local authentication

  You are right in your diagnosys of the problem, we see this from time to time and there is not much that can be done unfortunately.

  The only way is if the remote peer Gets a subnet or a dynamic address on a particular beach all the time, then add a line "isakmp key... No.-xauth" with this defined subnet. For example, if the remote peer always receives an address in 4.104.225.0/24, then do:

  > cry isa key address 4.104.225.0 255.255.255.0 no.-xauth

  Not much, but it's the only way around it.

• VPN with dynamic IP. How to use DNS?

  Hello

  I installed a site to site VPN IPSec between two routers cisco IPs public Static. I notice that I can use dynamic IPs for the case with point-to-multipoint or IPs instead host names. In this case, I can use this command to configure the VPN:

  (config) #crypto isakmp identity hostname

  (config) #crypto isakmp key XXXXX hostname 'Remote_name '.

  (config-crypto-map) # defined peer 'Remote_name '.

  I also noticed that I can use a router cisco as a DNS, and I can add the host records with:

  IP host 'Remote_Name' "IP address"

  In fact, I want only one router to work with Static public IP (Router_A) and the other with the dynamic public IP (Router_B) of ISP address. Then maybe I can put the router with static IP address to work as the DNS server. I know how DynDNS works with an account and update client software on a PC/server, but I've never used the hardware update DNS clients, and I don't know what steps I must follow to implement this.

  Hi John,.

  The section in the link below should help you to configure DDNS on your router:

  (See example Http update)

• ASA - s2s vpn with dynamic ip - Dungeon tunnel upward

  Hi guys,.

  We want to set up a vpn between our central asa5520, and a new branch office asa5505 with dynamic public ip address.

  This type of configuration is supported, but the tunnel can only be initiated from the asa distance (the asa central do not know how to reach the asa remote).

  prove that on this vpn also transit traffic voice, we must always maintain the tunnel.

  A solution would be to have a kind of continuous ping from the remote office to the central office... is more 'professional' wat to reach our goal?

  Thank you.

  Try, 'management-access to the inside' of the asa and ping

• VPN site to Site if a distance ASA has a dynamic IP address outside

  Hello

  I always try to find the right commands for dynamic VPN to VPN from Site to Site.

  I found something on the set by the peers command, but is exactly what I want to do?

  Static IP on both ASA (asa5505 and asa5510):

  peer set card crypto outside_map 1 192.168.178.230<== that="" ist="" for="" a="" static="" if="" i="" know="" the="">

  A (asa5510) static and dynamic (asa5505) IP:

  by default dynamic value of the card crypto-outside_map 1-set peer asa5505<== is="" that="" the="" right="" set="">

  If the ASA remote called asa5505 and he has a dynamic IP address?

  Kind regards

  Hans-Jürgen Guenter

  Yes, you need not the 3 lines above in the configuration. Those who are kept on the static end to accept the connection from the dynamic counterpart.

  You need not order 'set by the peers' you don't have a static ip address for the dynamics of the end.

  Hello Tony,.

  Just because u asked him

  Use the following syntax:

• DMVPN with dynamic failover HSRP/IPSEC

  "DMVPN with dynamic failover HSRP/IPSEC."

  Hi all. Is this possible? When you use a direct IPSEC LAN to LAN, you have a card encryption and when you secure the card encryption at the source of the tunnel interface, you configure "' crypto map redundancy with State '."

  The DMVPN does not use encryption card, sound by using an IPSEC profile with protection of tunnel. How you configure stateful with HSRP IPSEC in this situation?

  We're heading for a double cloud dmvpn topology with 2 heads dmvpn geographically separate. I want that every network head to have a redundancy HSRP, which can be done fairly easily. But I also want State IPSEC to be replicated for all security associations IPSEC do not fall in the case of a failover. Is it possible in this scenario and how?

  Thanks a lot as always.

  Hello again ;-)

  There are currently no plan at the moment (that I know) to mix with State redundancy and anythign with protection of tunnel.

  Frankly it is best to create redundancy in DMVPN termination on both turntable and relying on routing protocols - which I am sure you aware of so I won't bore you with details.

  That said, my personal observation is - if you want a failover go to ASA, when you have routers, you have all these wonderful tools like VTI/GRE for IPsec that mix well with routing protocols, and MUCH MUCH more. It is very often to change some timers for routing protocol driven "failover" happen very quickly.

• VPN client with counterpart on secondary ip address on the public interface of the router

  Hello

  On our office LAN, we have a Linux server than it hosting a VPN connection to a remote client.

  Do this to ISAKMP card on our Cisco router port connections to the internal ip address of the Linux host.

  However, we now want to allow our users to establish VPN connections to our local network using the unit of Cisco VPN Client.

  Of course, this would present challenges, as the ISAKMP our router port is mapped through an internal host.

  So, we tried to set up a secondary ip address on the router and VPN clients to connect to that.

  What we see in our newspapers is as follows:

  Phase 1 is very well established, and the VPN Client prompts the user for a user name and password.

  Authentication of the phase 2 starts, but the router says it's is not to receive a proposal of hash of the client.

  185 12:18:06.943 09/03/11 Sev = Info/4 IKE / 0 x 63000014
  RECEIVING< isakmp="" oak="" info="" *(hash,="" notify:no_proposal_chosen)="" from="">

  (in this case, where x.x.x.x is the secondary ip address on the public interface)

  After that, the Phase 1 SA is removed and the connection fails.

  My understanding is that the Phase 2 negotiation takes place with the ip address assigned to the client in Phase 1, which suggests that the problem occurs because the client communicates with the main on the interface ip address, and no secondary ip address.

  When remove us the mapping of port isakmp and the VPN client to connect to the primary ip address, everything works fine.

  Question:

  It is possible to establish 2 router VPN Client uses a secondary ip address?

  If not, is there some way I can implement the port mapping so that it occurs, the connection comes from a specific ip address?

• VPN IPSEC ASA with counterpart with dynamic IP and certificates

  Hello!

  Someone please give me config the work of the ASA for ASA Site to Site IPSEC VPN with counterpart with dynamic IP and authentication certificates.

  He works with PSK authentication. But the connection landed at DefaultRAGroup instead of DefaultL2LGroup with certificate

  authentication.

  Should what special config I ask a DefaultRAGroup to activate the connection?

  Thank you!

  The ASA uses parts of the client cert DN to perform a tunnel-group  lookup to place the user in a group.  When "peer-id-validate req" is  defined the ASA also tries to compare the IKE ID (cert DN) with the  actual cert DN (also received in IKE negotiation), if the comparison  fails the connection fails. know you could set "peer-id-validate cert"  for the time being and the ASA will try to compare the values but allow  the connection if it cannot. 

  In general I would suggest using option "cert."

  With nocheck, we are simply not strict on IKE ID matchin the certificate, which is normally not a problem of security :-)
