WRVS4400N and dynamic DNS

I need assistance with my WRVS4400N (its Firmware Version on: V1.1.03, I think that the more recent on this product) with VPN.

At one end of the IPSEC VPN is this router. three other ends are WRV210.

I noticed that if if I have a site that has an ISP who changes IP very frequently (in this example 2 site), the problem is that the WRVS4400N will know the new IP address on the summary page, but retain the old IP on the configuration page.

Here's what I mean.

(1) if I set up the following VPN will display.

N ° name State P2 Enc/Auth Local Group remote control Remote Gateway
1 place 192.168.1.0/24 BRANCH1 192.168.100.0/24 3DES/SHA-1 221.100.100.10
BRANCH2 2 place 192.168.2.0/24 192.168.100.0/24 3DES/SHA-1 221.100.100.20< notice="" this="" is="">
3 place 192.168.3.0/24 BRANCH3 192.168.100.0/24 3DES/SHA-1 221.100.100.30

(2) if 2 PSI (short DHCP lease time) branch forced a change in intellectual property

N ° name State P2 Enc/Auth Local Group remote control Remote Gateway
1 place 192.168.1.0/24 BRANCH1 192.168.100.0/24 3DES/SHA-1 221.100.100.10
2 Down3DES/SHA-1 192.168.100.0/24 192.168.2.0/24 221.100.100.22 BRANCH2< new="" ip="" is="">
3 place 192.168.3.0/24 BRANCH3 192.168.100.0/24 3DES/SHA-1 221.100.100.30

(3) what I'm doing is:

(3A) go to change Edit, Branch2, the remote gateway IP/resolved by the DNS to IP/IP, and I see

IP resolved by the DNS: branch2.dyndns.org---> IP address: 221.100.100.20 (note that it retains the old IP)

I change to the new IP 221.100.100.22 and the tunnel will go up

(3B) or simply reboot the router and the tunnel will go up.

It seems that the problem is a bug in the firmware, when I really need to do something is the ' ipconfig/flushdns' line on the box.

Is that what anyone has experienced the same problem?

    Linksys supports States that I need to contact verizon DSL to get a public IP address and set up a "bridge connection" in the DSL modem.  I would try even when using dynamic DNS.  If someone is successful with this change I would appreciate some tips

    To use the dynamic DNS on the WRV you will need a public IP address on the WRV and for what the modem needs to be filled. This brings you straight to where you already are.

  • See dekstops and dynamic DNS updates

    In general, I always do an ipconfig/release on the VM parent to make sure that its IP address is not carried over to the clones.  When creating, pool and virtual computers start, they are able to get an IP address and DNS name is registered.  However, the new virtual machine has without the permission of its DNS record, so it cannot dynamically update its DNS record.  I have to manully updated each DNS record, allowing each VMs computer complete object to its respective DNS record.  Obviously, it is not well-suited.  I did something wrong in the configuration or is this a problem with view 3?  Thank you.

    I see no reason for your question, but I don't have this problem because my XP SP3 virtual machines are their acquired DHCP quite happy with my DNS server addresses. Looking at permissions associated with a DNS record, virtual machine computer account has permissions specific, not hereditary, (write all properties, read permissions, all validated writes). They are in a non-persistent pool and I did not communicate the IP address before you close the image gold and taking the snapshot related clones are based on. Your master VM has been properly linked to your domain that I guess?

    I had set up dynamic DNS using no. - ip (NETGEAR supplier - "*.") mynetgear.com') on my router R7000, before.

    Now, I changed to a R7500.

    But my noip.com account still has the 'old' R7000 device under host / redirects-> manage devices.

    And I can't seem to remove the R7000 and serial number. (and I don't have the R7000 no more).

    The R7500 refused to apply the account settings for:

    Service provider: NETGEAR

    Hello

    I can't remove the R7000 go in my list of devices (or at least, I can't find a delete option).

    BUT after removing the hostname of my old camera AND delete the full host name subsequently (on noip.com), I could re-register the R7500 with my host name. So ultimately it works again!

    Noip.com, on the R7000 is more listed as acive device, but it seems that I can't delete the old of my list.

  • Dynamic DNS update of IPv4 addresses does not not in Windows 7

    Several months ago, we noticed behaviors incompatible with Windows 7 clients and their entry in DNS Active Directory.

    The main problem is that our Windows 7 clients only will be not systematically their IPv4 address in Active Directory DNS by using dynamic DNS (RFC2136)

    Initial question:

    • A handful of customers will register its IPv4 address, but it is a minority and most don't (this is the main question)
    • We use the public IP address space.
    • Customers have been constantly recording the IPv6 address for 6to4 in DNS card but not its IPv4 address.

    We have disabled the 6to4 map by using Group Policy, because we do not use IPv6 and don't plan to use the 6to4 transition.

    Secondary issue:

    • Customers is no longer recording card 6to4 in DNS (good)
    • Majority of customers do not yet record their (bad) IPv4 address.

    What I've checked so far:

    • Analysis using Wireshark:

      • Most clients make no request for SOA record and therefore do not try to send dynamic DNS updates.
      • Some customers get the AD zone SOA record and then send the DNS dynamic update to one of the DCs.
      • I see nothing of clearly different on clients who send updates and those who are not.
      • All the other AD related traffic, for example request/response for domain/ldap SRV record looks normal.
    • Settings on the client:

      • The IPv4 adapter "save addresses for this connection in DNS" checked.
      • The primary DNS suffix is the same as our AD domain name.
      • The AD domain name is a COMPLETE domain name.
      • Use us group policy to apply the primary DNS suffix and some connection specific suffixes.
      • Customers do everything they are supposed to; as access to shared resources, printers, etc. - just not update DNS.

  • Dynamic DNS in RV130

    Hello

    I have a RV130 connected to the internet router/modem and I have configured the dynamic dns (No. - ip provider).

    the problem is that the ip address that is returned to the ddns is the rv130 wan ip, not internet ip address.

    If I use a machine on the network with the app to no - ip, it shows the internet ip in site no. - ip address, but since it is a customer that I can just ask her to keep a machine always on execution of the application.

    is it possible to change the configuration on the rv130 or is this something I need to change the modem?

    thnx

    Hello

    There is nothing you can or need to change on the router, it will report the IP address on the WAN connection.

    Based on what you say, I think the problem is that the modem, the RV130 is connected to is acting as a router and providing a kind of IP address in the RV130 (10.x.x.x or 192.168.x.x or 172.16.x.x)

    What you need to do is to contact the ISP and have them change the modem in Bridge mode so that the actual public IP goes directly into the WAN port on the RV130 and then the DDNS will show the correct address.

    I hope this helps.

  • Difference between static and dynamic encryption card

    Anyone tell me the difference between static and dynamic encryption card?

    Hi Rodrigo,

    Public static crypto map - identifies by the peers and traffic to encrypt explicitly. Generally used to host some tunnels with different profiles and characteristics (different partners, sites, location)

    So, when you have the information of the two peers than what policies we're going to use, what is the IP on both devices we normally use static VPN.

    Crypto dynamic map - is one of the ways to accommodate peer sharing the same characteristics (for example, several offices of branches share the same configuration) or peers with dynamic IP addressing (DHCP, etc.)

  • Ice, liquid and dynamic data (modules and applications) - just a suggestion

    Hello!

    It is a position of more suggestion rather than a discussion message. I'm not sure that having placed in the right area, so excuse me if I don't.

    1. I was very happy to work with liquid to display things when a user is logged on and stuff so that it was not. Until I realized that my site in full could not be editable through the ice, because I used all liquid through the site. Liquid is amazing, but it would be more surprising if it can work with ICE. Is this something BC have in mind for future versions?

    2. it would be so great that ICE would allow my clients to edit blog, products, applications, and data FAQ. I think you must have a glance, that Webflow people do with their CMS. Their CMS allows people to change static and dynamic content with an interface similar to ice BC plans to implement a similar feature in the future?

    Thanks for reading this,

    Diego.

    While BC is working better and more recent versions of ice and I'm sure will better work with the new features of British Colombia as a liquid, due to the nature of the liquid and the coding side Server with conditional statements and complex solutions, you can create - with ice you can pretty well bet that he used to be able to support what your specifically ask in all cases. Keep this in mind.

    With more capacity edit on other things - I am course will be in future versions.
