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.

    Hello

    Would you please help me on this:

    What is the cheapest Cisco router for a desktop environment 10 to 20 employees that supports DMVPN or any other technology to maintain a permanent IPSec tunnel, not question that the provider of services at this office only allows dynamic allocation of IP address?

    I know about 2801 and 1841, but is it possible to go even lower?

    Kind regards

  • 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).

  • Message came up with, "Windows has detected another computer with the same IP address on this netework."

    A message came that said, Windows detected another computer with the same IP address. "... or similar message to one, that could just be the functioning of the laptop for the wireless?

    MurrayJoe:

    > Mean someone has or may have access to my PC or laptop?

    You mentioned a wireless laptop. Do you get this message at home (when your laptop is in communication with your own wireless router), or that you get this message when in a public hotspot?

    If at home, then I would be not too concerned (what security options enabled in your home router?).

    If you get the message while using a public access point, this does not necessarily your computer has been hacked... but it is a warning that you should not ignore. In general, I would not go to any site that has my financial data, or any other sensitive data, a public hotspot. There are too many ways that a public hotspot may be compromised.

    Your original post said that "a message came that said, Windows detected another computer with the same IP address.

    There are several reasons this could happen... some innocent people and some not so innocent.

    If your network is configured for the most common way, then your router uses a feature called Dynamic Host Configuration Protocol (DHCP). You can read about DHCP here...

    http://en.Wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol

    Basically, when a device on your home network needs an IP address, he asks your router and your router assigns an IP address... technically, "rents" the router address for a given period (one day). Once this period has elapsed, the device must 'renew lease'.

    DHCP stops you from the hassle of having to assign a static IP address to each device on your network and then don't forget to retrieve that meet if/when a device are removed from your network.

    Sometimes the process DHCP can be confused and assign the same address on multiple devices. If/when this happens, communication between devices on your home network may be confused. Windows is smart enough to detect that another device on your home network has the same address as the computer where Windows is currently running..., but Windows can not solve the problem.

    You can determine the IP address of the computer that is running Windows (and posted the message you saw)... by entering "ipconfig" (without the quotation marks) at a command line prompt. Then you can check the IP addresses of all devices on your network until you find the other devices with the same IP address. Then you could say either every device to get a new IP address of the router (or restart the device). Alternatively, you can try just stating the computer that is running Windows to get a new IP address (by first entering "ipconfig/release" then "ipconfig / renew" in the command-line invite him... all orders without the quotes).

    But since you said that you are not very tech savvy, my first suggestion was the easiest... just shut everything in your network, and then restart one at a time by starting with your ISP device, router, and other devices. If the problem persists after that, then more troubleshooting (as described in the previous paragraph) would be necessary.

    I hope this helps to clarify the issue for you. If you have any questions, please post them and I'll try to answer.

  • WAG325N, DHCP, and the DSL dynamic IP address

    Hello. I have problems with the implementation of my router, a Linksys WAG325N. My internet connection is DSL. According to my ISP, I have no username or password for my account because my connection uses a DYNAMIC IP ADDRESS. The operator of my ISP tells me that for my WIFI connection all I have to do is to set it to DHCP. That's all. My ISP does not help me because they sell another brand of routers with their DSL...

    My default IP address is 192.168.1.1

    I use to access the control panel of the CIsco modem. No matter what I do, the light of the internet on the router is always Red; the power, ethernet, DSL, and wireless lights are all yellow.

    What should I do?

    Thanks in advance and MERRY CHRISTMAS to all!

    Finally fixed it!

    Here's what I did:

    Encapsulation: RFC2684 Bridged (thank you GV!)

    Multiplexing: LLC

    Called my service provider for these values:

    VPI: 0

    VIDEO RECORDER: 100

    So that anyone who is going to be having the same problem I did find this:

    My ISP is PLDT MyDSL. My linksys model is WAG325N.

    Merry Christmas to all!

    Thank you once again, GV!

  • WRT160N: Getting dynamic IP address 169

    Hello!

    Linksys WRT160N, bought yesterday and I want it behaves same way did my Buffalo WHR-HP-G54. So I live in apartment building for students, and we don't have modems, just the RJ-45 ports in the wall. If I plug the cable directly from the wall of the network card in my computer, my computer receives the dynamic ip address from the ISP. With my Buffalo, I connected the ethernet to the WAN sa-port cable and changed the router in bridge mode. In this way, there was 4 other ports free for the other PC and of course wireless too much for the other PC. Each PC connected via the Buffalo had a dynamic ip address from ISP, up to five addresses, which is the limit of my ISP. I plugged the ethernet cable from the wall of WRT160N Internet port and disabled NAT, dynamic routing (RIP) and DHCP server on the router Linksys, so all my computers have addresses ip starting with 169. And when I plug the ethernet cable from the wall to a port other than Internet-port of Linksys, all computers get the correct IP addresses via a wireless cable. What is wrong, is at - it a setting I have not seen? Some setting that I can use Internet-port and have other 4 free ports for other devices and other devices can get dynamic IP from my ISP.

    Ignore the Scrooge. What he wrote has nothing to do with your problem.

    Unlike the Buffalo WHR the Linksys doesn't have a configuration option or switch to alternate between the 'bridge' and the router mode. The Linksys always uses the internet port on a different interface of the numbered ports. You can't fill.

    For example, if you want to 'bridge' with the Linksys is the configuration you already have when wiring from the outlet ports numbered, i.e. do not use the internet port. You will have to "give up" the internet port then. If you need more wired ports, you must connect a switch to the router.

  • How to change (dynamic) IP address in Windows 7 or Vista?

    Had the same problem on Vista, upgrade to Win7 and the question remains.

    I have a dynamic IP address from ISP, but it remains as if it was static, what allows to work in XP and previous versions of Windows no longer works in Vista or 7. I talked to my ISP (3 times, 3 different Tech), they said that my IP is dynamic and confirmed he is not defined by them as static. They charge more for a static IP, it would just give me this free 'upgrade'. They had "no idea" how to force/change a new IP address in Vista or 7.

    Please! Don't bother suggesting to run ipconfig/flushdns / release / renew at the prompt to as suggested by each internet search, this DOES NOT WORK. This was done with the prompt window of cmd under "Run As Administrator".

    Please! Read everything I've done here before suggesting something, I have tried or have tested and proven to work/not work.

    Here are other things that I've tried, WHO ALSO DO NOT WORK:

    (NOTE: no router is used, directly connected, CAT5, NIC the modem PC broadband)
    -Modem unplugged 72 hours left. No change
    -A the ISP send me a new modem. No change
    -Uninstalled NIC. No change
    -Change IP4 settings to "Obtain automatically" to a forced IP made-up, rebooted, then changed back to auto. No change

    So, with all this 'old school' stuff already tried and failed, that changed in Vista and 7 which seems to keep the same dynamic IP static? When Windows is put in cache or store this information, so I can delete it, none of the traditional methods of work. I absolutely can't stand having a static IP address on my computer at home.

    If you search on the internet this exact question you will find what I have, everyone is suggesting to the methods of work time I tried already above, but people using Vista or 7 are several times to find it no longer works.

    Here is some information, which confirms the IP address is not stored in my modem, or assigned to the MAC address of my NIC...

    If I start this same PC with a LINUX Live CD, type using the same MAC address and the NIC, he gets another IP address whenever it restarts. The question clearly has nothing to do with my ISP, modem or PC in general.

    If I get hot swap my modem to another PC, the other PC Gets a fresh (different) IP address. If this another PC using XP I can force the ipconfig/release / renew to change its IP address.

    If the other PC running Vista, the IP address remains static, no matter what I try, unless the hard drive is wiped and Vista is re-installed, then he gets a new IP on the PC with the pure install, but it can not be changed after what is happening.

    If clear, Windows Vista and Windows 7 have somewhere IP configuration information and re-use of this information when it detects that you are using the same internet provider, WHERE is it stored so I can delete it?

    I thank you much if you have a working solution and actually know the answer, instead of reading everything that can already be found by a search engine and repost info which is no longer valid, as all the world on the internet is doing in trying to answer this question.

    I think I found a solution. It has worked for me so I guess it could work for you.

    1. find your IP address for example to go to a site such as http://www.whatismyip.com/ it will show you your IP address.
    2 copy.
    3. open network & sharing Center
    4. open the network properties you what your IP to change. In my case, it's an EVDO modem.
    5. on the network tab, double-click TCP/IPv4, which will open a window to change the IP and DNS IP address.
    6. in this window click on "use following IP address" and paste this IP address you copied in step 2.
    7 change the last digit of the IP address to any value above him for example if its 192.168.23.123 change the last digit to something like 122 so that the IP address becomes 192.168.23.122.
    8. click on OK until that close all windows.
    9 disconnect from this network.
    10 reconnect to this network and if it goes as planned the ISP should force a dynamic IP address. Check http://www.whatismyip.com/ if it has changed. If you can not browse, go to step 6, and then select "Obtain an IP address automatically" and then disconnect-> reconnect to the network.
    It worked for me so I don't know if it will work for you. Your comments will be greatly appreciated.

  • "Error: failed to get the IP address of the destination virtual machine running the converter to assistance server." with a static IP address

    Hi all

    I'm trying to p2v linux 6.4. It fails with the following message is displayed:

    Error: Cannot get the IP address of the virtual destination machine running the converter assistance server.

    I have seen discussions on this message, but they all refer to dynamic IP address, taken from DHCP, as in my case, I use static IP address.

    In the meantime the p2v (which then breaks down...) I open console support machine and saw a message:


    eth0 is not a recognized interface.

    Can someone tell me what is happening?

    Hello

    I assume you are using converter 5.5. There is a new feature that allows the selection of the network card. However, it works well in the case of Linux P2V. If you have changed the type of adapter, use 'e1000' or 'auto' and try again.

  • Problem installing oracle 11 g 2 in a virtual machine with IP dynamic

    Hello

    I have install oracle 11 g 2 on a virtual machine in Vmware workstation with dynamic IP address.

    Then I noticed that the global database name is orcl.16.27.57, and the identifier service oracle is orcl on step 10 of window 19

    There will be a configuration manager warning and the company failed due to the following error:

    Listening is not or the database service is not registered with it.

    And even I change the name of global database for orcl, it has also failed.

    When I use the static IP, the name of the database world so SID is orcl.

    then complete the installation.

    So I don't know what the reason is, how to install it without warning during the dynamic use of IP.

    Whenever I have install oracle with static IP, I can't continue like that again.

    Help!

    Thank you

    Now, I'm happy to say it works. Two methods to solve this problem.

  • Server 2008 (R2): dcpromo fails due to dynamic IP addresses

    It is my first installation of Windows Server 2008. Maybe someone has an experience with this?

    I installed Windows Server 2008 R2 in a VMWare environment. For networking, I chose Host-only in VMWare Workstation and installed Windows Server 2008 R2 Standard.

    After that, I added the AD DS role for my installation of Windows Server 2008 R2 and run DCPROMO. EXE...

    The arrested installation process between the two because of the dynamic IP addresses. I went into the properties of the LAN adapter and changed from a static IPv6 address. (I disabled IPv4).

    After that restart dcpromo still refuses to go beyond the point where it looks for dynamic IP addresses. He seems not to recognize the static I chose.

    There may be something to do with my computer? I don't think he has a related issue R2 because Active Directory has not changed "r1".

    Any help is appreciated.

  • What does this mean and how to fix: the router address you entered is not compatible with your WAN IP address.

    I connect to an access provider via Airport Extreme, which is extended through two Airport Express.  When I try to edit anything in one of these devices, even a name, I get this message: "you have entered the address of the router is not compatible with your WAN IP address.  My connection seems to work, but there is clearly something wrong with her.  The Express has no DNS and will not update without the same message.  I have no idea what this is all about and will greatly appreciate the ideas.

    This means that WAN Setup does not or does not install across the network.

    The best way to solve this problem is beginning on...

    Reset all three at the factory and reconfigure each in turn. Do the extreme first and make sure it works... Then add the express.

    If you need help with that we will need to know which modem or modem router to your ISP gave you and possibly the type of services to wide band... and who is the provider.

    Give us screenshots of each installer as you do.
