Yeah, that one just don't cut the mustard. Try "ddclient". I started a thread a long time ago comparing different dyndns clients, and found "ddclient" had the richest feature set, including a lot of support for you router folk.
Try this thread.

How to Configure bootpd to Perform Dynamic DNS Updates

I have been able to get bootpd configured to function as a basic DHCP server. I would now like to configure it to dynamically update DNS forward and reverse zones when leases are assigned, released, or expired.
Does anyone have an example of a bootpd.plist file to configure bootpd for dynamic DNS updates?

Hi,
I am not sure what you are attempting to configure here.
But what the NAT configuration above does is do a Dynamic PAT for all the servers on the "firewall-dmz" to a single IP address towards the "firewall-outbound"
This Dynamic translation doesnt however enable connections to be initiated from behind the "firewall-outbound" interface. When your hosting a server which needs a NAT towards the users then the NAT type has to be Static NAT or Static PAT.
Static NAT will essentially use up one public IP address for just the single local host/server.
Static PAT will do a Port Forward from the public IP address and public port to the local IP and local port. And this is most commonly used with environments which only public IP address is the one that the ASA holds in its WAN interface.
A typical Static NAT configuration is this
static (inside,outside) 1.1.1.1 10.10.10.10 netmask 255.255.255.255
Where
inside = is the interface behind which the host is
outside = is the interface towards which the host is NATed
1.1.1.1 = is the public NAT IP address for the host
10.10.10.10 = is the local IP address of the host
A typical Static PAT configuration is this
static (inside,outside) tcp interface 80 10.10.10.10 80 netmask 255.255.255.255
Where
tcp = specifies the protocol for which the Static PAT configured
interface = specifies that we will be using the public IP address of the destination interface "outside" as the public IP address for this single Port Forward.
80 = first "80" specifies the public port visible to users behind the destination interface
80 = second "80" specifies the actual local port on which the local host is listening on
Hope this helps

DHCP dynamic dns updates for Chromebooks fail

Hi all,
We're having a bit of a problem here. We have a domain here, domain.local, that has approximately 260 Windows Machines (XP, Win7, various MS Servers) and we also have users that bring in iOS devices, Kindles, Androids and so-forth. The domain controller
runs dhcp, dns, wsus, and is a file server. We only have a single dhcp server and a single dns server on a Windows Server 2008 R2 box.
We have a wireless network by Aruba that has three SSID's on it. One is secure, two are firewalled and open. You can ping the chromebooks on either of the wireless networks. the DHCP server works find on all of these.
We started off getting bad_address entries from the chromebooks when they went on our network back in September. Creating a dhcp lease solved most but not all. We are still getting dozens of entries in the dhcp log that specify bad_address. We have the dhcp
server testing twice before issuing. Once in a great, great while, we might get something on an Android, but that is it.
Funny thing is, Chromebooks are being handed IPs (horray) and we can see the leases in the dhcp server. Well that really isnt funny, but what is, dynamic updates to dns are not happening. They exist nowhere in the forward zone or as a reverse pointer.
Kindles, iOS machines, Androids, Windows machines and everything else work flawlessly.
So two things... bad_address in the dhcp area and the dhcp dynamic updates are not happening for the Chromebooks.
Dns is set to "Always dynamically update DNS A and PTR records.
Discard A & PTR records when lease is deleted is checked.
Dynamically update DNS A and PTR records for DHCP clients that do not request updates is also checked.
Name protection is turned off as of today.
Any Ideas?
Thanks!
Steve

The chromebooks are not joined to the domain. They are not designed to do so.
DNS Suffix is fine.
We have intermittent issues with Androids and an occassional iOS device, but never Windows machines.
Here is part of the log from yesterday. Only two bad_addresses happened today. See what I mean by it's intermittant?
Thanks!
Steve

RW215W Dynamic DNS update interval

Hi,
I have a RW215W Router. Using a mobile broadband dongle for internet connection and the public ip changes every time the dongle is connected. I´m using a ddns service. I need update the new ip to the ddns service more frequent or when ip changes. Is this possible? any suggestions?

Hi,
Please check if your multiple DHCP has joint the group DnsUpdateProxy or not. To do this, you can refer to:
DNS Record Ownership and the DnsUpdateProxy Group:
http://technet.microsoft.com/en-us/library/dd334715(WS.10).aspx
Also check if the client service “DNS client service" is running fine.
Meanwhile, please refer to these articles:

Dynamic DNS updates and issues with re-imaged / replaced machines with the same computer name

Our AD team gets asked frequently to delete bad DNS entries because a computer was replaced or VDI was re-created, and when it was joined to the domain it had the same computer name but different SID, so the DNS entry for that computer can no longer be updated
to a new IP address because the new computer doesn't have rights to update that object in DNS.
I recently saw a resolution to this was to set the security for DNS to allow updates from "Domain Computers" as described in the KB below.
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2005210
Has anyone done this? Any negative implications from this?
Thanks

Granting all domain computers write access to all records in the dns zone does solve the problem. On the negative side, DNS security is reduced significantly. For example, any user with admin rights locally on his/her computer will be able to sabotage
services in your domain by deleting or changing host records of domain controllers, servers or other client computers.
A more secure solution in this case will be configuring DHCP servers to update DNS on behalf of the client and granting DHCP servers appropriate access to DNS zone. Take a look at
Configuring Secure Dynamic Update for more info.

Multiple Public IP's on one physical interface for devices behind Router.

Hi guys, I am trying to find information on applying multiple IP addresses to a router
basically one for the Router itself and then some for the devices behind the router, Which i am sure I need to apply some 1 to 1 NATs. I just do not know if i need to specify all the IP addresses on the main interface.
Example being I have a router with WAN ip of xxx.xxx.xxx.xxx/25 , it only has 2 interface one for WAN one for LAN, i have a server I would like assigned its own public IP address. but still on the same LAN network.
Could someone help me out and point me in the right direction with a sample config

I agree with the previous response that you need a static NAT to allow outside resources to initiate traffic to your server. You also will need NAT or PAT using the router interface address to allow the other hosts in your network to access outside.
You do not need to configure any other of the addresses on the router interface other than the primary IP that you assign to the router interface. As long as the other addresses are used for NAT/PAT they are configured in the nat statements and not on the physical interface.

HB3 / Dynamic DNS Update time

Does anyone know;
1. What the default update time is on the dymanic DNS settings and
2. is it possible to amend it?
thank you

If you mean can you alter when your IP changes no I don't think you can. I have had one for 6 weeks and the next for a few days. A

Using Airport Extreme 802.11n to update automatic IP for Dynamic DNS ???

Hello,
does anybody now if it is possible to use Airport to forward the recent IP address to DynDNS.com ? As most routers are able to forward the IP to a provider like DynDns eachtime when IP address is renewed . I have found at the Airport Configruation Utility in the manual configuration the following fields: Button Airport -> Button "Basic Station" next to the field Airport extreme name the Button "config" -> a new pop up opens and at the bottom I am able to activate "dynamic global hostname" and to fill in the user ID + password. But the IP address is not updated at DYNDNS.com
Has anybody experience with Dynamic DNS and Airport extreme ?
Thanks in advance
Stephan

DNS record ownership for DHCP clients

my configuration:
dhcp/dns/dc installed on same system - Windows 2008 R2 SP1 in domain environment.
all zones configured to secure updates only with aging and scavenging enabled
dhcp servers are member of DNSupdateproxy group.
dhcp are configured with standard domain user account (this user was made a member of dnsupdateproxy as well, DOES THAT MATTER?)
dhcp scopes are configured with default DNS setup (force DNS update by DHCP)
now...
all DNS records for endpoint devices on dhcp lease (windows7, mac os X, ubuntu) are owned by SYSTEM
in security tab for some DNS records i can see service account with write permission to record ( i believe this is desired state)
in other records service account has no permission but timestamps are still updated by computer account (hostname$ has write permission). these records have pencil icon on computers in dhcp lease table.
Problem with this (hostname$ has write permissions) is when user connect to network via VPN (obtains dhcp lease) it get's two records registered in DNS -> 1 record for ip distributed by dhcp server and 2nd record for his home private network.
Have anyone seen this before?
i've tried deleting DNS records / releasing ip on endpoint device (example win7). It would not register to DNS by DHCP. However if i do ipconfig /registerdns it will do it, but dhcp service account won't have permission no this record.

Apparently it appears that DHCP may not be configured with credentials, DHCP DNS settings are not configured to force DHCP to register ALL requests, nor has the DHCP server itself have been added to the DnsUpdateProxy group. These are all prerequisites
for DHCP to own all records, otherwise you will see default behavior, which is:
By default, a Windows 2000 and newer statically configured machines will
register their A record (hostname) and PTR (reverse entry) into DNS.
If set to DHCP, a Windows 2000 or newer machine will request DHCP to allow
the machine itself to register its own A record, but DHCP will register its PTR
(reverse entry) record.
The entity that registers the record in DNS, owns the record.
In summary:
Configure DHCP Credentials. The credentials only need to be a plain-Jane, non-administrator, user account. Give it a really strong password.
Set DHCP properties, DNS tab, to update everything, whether the clients can or cannot.
Add the DHCP server(s) to the Active Directory, Built-In DnsUpdateProxy security group.
Make sure ALL other non-DHCP servers are NOT in the DnsUpdateProxy group. For example, some believe that the DNS servers or other DCs not running DHCP should be in it. They must be removed or it won't work.
On Windows 2008 R2 or newer, DISABLE Name Protection.
If DHCP is co-located on a Windows 2008 R2 or Windows 2012 DC, you can and must secure the DnsUpdateProxy group by running the following:
dnscmd /config /OpenAclOnProxyUpdates 0
Configure Scavenging one one DNS server. Set the NOREFRESH and REFRESH values combined to be equal or greater than the DHCP Lease length. What it scavenges will replicate to others anyway.

OS X 10.6.1: bootpd, named, and dynamic DNS zone updates

I have OS X 10.6.1 installed on a Mac Pro. It is configured to be the name server and DHCP server for my home network, i.e. /etc/named.conf and /etc/bootpd.plist have been modified to provide these services.
I've encountered no problems with either the name server or the DHCP component of bootpd after upgrading to OS X 10.6(.1); however, one thing that continues to bug me is how to configure bootpd to dynamically update the DNS zone files whenever a lease is issued, released, or expires.
At work, I use the Internet System Consortium's DHCP software and have it configured to dynamically update DNS whenever leases change state. I would really like to have DNS done the same way at home.
What changes need to be made to /etc/bootpd.plist that would allow dynamic DNS updates to occur?

Did you ever get an answer to this? Would rather not change the DHCP server in Snow Leopard....
Thanks

Actiontec MI424WR-GEN3I with ChangeIP dynamic dns

I'm trying to configure my router (Actiontec MI424WR-GEN3I, v. 40.21.10.3) with ChangeIP.com dynamic DNS. It's listed in the provider drop-down in the Dynamic DNS section of the router GUI, so i figured i'd be all set. I setup an account with ChangeIP, and then got a hostname from them.
In the router i'm configured as follow..
Hostname: MyHost.changeip.com (<-- actually MyHost.onmypc.org; "onmypc.org" being one of the domains ChangeIP offers for free.)
Connection: Broadband Connection (Ethernet/Coax)
Provider: changeip.com
Username: My changeip username
Password: My changeip password
Dynamic DNS System: Dynamic DNS
Offline: (not checked)
SSL Mode: None
In the status area it just says "Error - Unknown changeip.com error". There's nothing in the changeip knowledgebase. Has anyone tried configuring changeip on their router? I know they have something called homeing beacon, but really i just want this to work as configured without having to install anything extra.
Thanks!

Hello, I had the exact same problem. It seem Verison FiOS router is not very flexible. You can't enter another Dynamic DNS (DDNS) and can only use one on the list. The only two free one I found was no-ip.com and changeip.com.
The no-ip.com came back with a host not found cause they've changed the name to noip.com (without the dash) so the dumb router is not able to find it.
The changeip.com is no help either as you've found out. I keep getting Error but it does not say why. Fortunetely I did found a solution. You can download changeip.com's DDNS Update Client (for Windows, Linux, or OSX). The called this software as Homeing Beacon.
http://www.changeip.com/accounts/downloads.php
In Windows it runs as a self startup service so you don't to remember to run it but you will need a Windows PC to be on for the update to occur. Basically instead of updating changeip.com's DDNS entry from the router, you have a Windows client that somehow figures out what the router's IP and act as a proxy agent and update your DNS entry on changeip.com. This is a workable workaround, I think. The drawback is you need a PC running every so often on your home network so updates occur. But, the price is FREE and you can't beat that.

Compatible Dynamic DNS Services

Does anyone know about ANY FREE Dynamic DNS service compatible with the Dynamic Global Hostname settings in Airport Extreme (MC340LL/A A1354)?
My registar/hosting (DreamHost) doesn't allow dynamic dns updates, except through local shell or perl scripts, or APIs on the web server — as far as I know. Dyndns.com only allows it with Custom DNS Zones, which are not free. And I would rather not use those silly update clients.
Oh, and I'm not willing to pay $99/yr for a MobileMe account just to have my home.owndomain.com pointed to my dynamic IP. Ain't gonna happen!
Thanks in advance!

Hi, Tesserax. Thanks for the welcome!
I've been using DynDNS with a D-Link router, but it got replaced.
Their words:

Which means it CAN be done, but only with Custom DNS. First, I think $29.95 for just a pointer is a little expensive; second, I would have to move my DNS services from my hosting. Too much ado, so I'm looking for an alternative — without success so far. I just want something that uses DNS Update protocol and TSIG security.
Meanwhile, I set up an API from my hosting and a perl script running on the boot to check if DNS is pointing to the right IP. It just works, clean and simple. But it's not a built-in solution and I cannot take advantage of wide area Bonjour, for example.
So, if does anyone know about it — a free dynamic dns service that uses DNS Update protocol and TSIG security —, please let me know.
Thanks,
Gui

Dynamic DNS (via DHCP) out of the box?

Greetings!
I was just wondering... Does OS X support Dynamic DNS updates out of the box?
I can't seem to find any confirmation if 10.5 uses bootpd (which I think it does), and if bootpd supports dynamic DNS updates with the named service built into Leopard Server. There don't seem to be any options in Server Admin to enable this... So I'm a little hazy as how to enable dynamic DNS without compiling my own version of ISC-DHCP.
Just for clarification here; what I'm looking for is the ability to update a DNS zone with a PTR/A record(s) of machines that send a hostname as a part of retrieving a IP address from a DDNS-enabled DHCP server. Ie, "mybox" requests IP from DHCP server, DHCP server updates "mydomain.tld" with a record for "mybox", so that "mybox.mydomain.tld" is resolvable afterwards by the machines on this subnet.
Cheers,
-SC

This is a strange topic because implementing Dynamic DNS on Mac OS X Server looks like it should be child's play... so why hasn't Apple done it? Could it simply be that Apple sees no need for it at this time? Mac OS X clients don't need it to sit happy with a Mac OS X Server. Neither do Windows clients using a Mac OS X Server PDC.
Apple has implemented Dynamic DNS client support into the Active Directory Plug-in in Leopard. In this environment, of course, the client's DNS server is most likely to be an Active Directory-integrated DNS server which happily support DDNS. Unfortunately this Dynamic DNS facility is not immediately available to those not using the Active Directory plug-in.

DNS update automatic

Dear all
I have one server running Windows Server 2008 R2 and that is part of our AD domain. This server is getting 2 network interface with IP addresses in 2 different VLANs. We would like to have only one IP address added to our AD DNS but unfortunately, every
day the DNS server is adding 2 entries for the 2 different IP addresses of that server.
I have unselected the value "Register this connection´s addresses in DNS" for the 2 network interfaces. This has not prevent the DNS update the next day.
I have created an entry DisableDynamicUpdate in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters and put a value of 1. This has not prevent the DNS update the next day.
Do you know what else could be done to fix this issue? Having the 2 entries is making some other applications failing.
Thanks in advance
Best regards
Yann

Hi,
Did you have DHCP server in domain?
Dynamic DNS registration relies on the Dynamic Host Configuration Protocol (DHCP) client service to perform dynamic updates. When you disable or set the DHCP client service to start manually, it prevents dynamic DNS updates from occurring.
