Address Reservation is not working on Netgear DGN2000 router

I believe you are going about this the wrong way. What you need to do is setup your address reservation for how many ever devices you want to run on your lan as "Static" addresses. It appears as if you have 9 total devices that need to be within the Ip address reservation block. Therefore, follow the steps below and this should help you. Let us know.

1) Set you Netgear DHCP server start and ending address as:
Start: 192.168.0.15
End: 192.168.0.254

2) Hard code ALL devices(Their respective NIC cards) in the address reservation block as such.
The available Ip addresses are: 192.168.0.2-192.168.0.14
It doesnt matter which ones you assign which Ips., but ensure that ea NIC card on a reserved address device has an Ip in that range.

Once all NIC cards are hard-coded with a static Ip within the reservation block of Ips, and the start and end Ip range for your DHCP server is set correctly, this should resolve you issue.  Your problem is that you DHCP server is set to issue ANY Ip address from 192.168.0.2 - 192.168.0.254.
With that said, your router really isnt reserving ANY ip address in your lan block of Ips. Furthermore, the Netgear router WILL NOT issue a reserved Ip to "ITs'"  configured device. The device needs to show the correct Ip coming from its NIC card to the router. You are the one that tells it(Netgear) the Ip  of the device by hard-coding each NIC card of the devices set to be in the reservation table. Hope this helps.

In addition to what I have said above, you basically want to ensure that ALL devices in the reserved block are assigned those Ip addresses (.2-.14) and that ea PC or devices' NIC card is physically assigned one of those Ips and not set to "Obtain Ip address Automatically" in the Network properties of ea device.

Thanks for your prompt reply.  If I understand you correctly you are saying that I need to set all devices to use a static IP address.  Surely this is the very reason why the address reservation table is used by the router to allocate IP addresses based on MAC address.  It shouldn't be necessary to set static IP address AND setup the address reservation table.  If I set my devices to use static IP addresses then I wouldn't need to use the address reservation facility of the modem to allocate the IP addresses, I could just set the DHCP start and end range to be different!

I did wonder if the DHCP server start and ending address should exclude all those IP addresses in the reservation table, however, this isn't the way my previous netgear modem worked.  I will try changing the DHCP start and end addresses to be greater than my reserved IP addresses and see if that makes a difference.

The address reservation feature on the Netgear does not issue addresses within the reservation Ip range. Therefore ALL NIC cards of those devices to be "reserved" needs to be physically assigned. The MAC address isn't assigned and or should not correlate the Ip address scheme of the reservation group. That view you see there is more for imformational purposes to view devices in the reserved table and what device has what Ip. The MAC feature would be more suited for the Wireless devices and security of the W-less network. Basically, even if you had NO devices listed in that reservation table and the start:end DHCP block was set as I described above, you'll still get your desired effect. The netgear knows not to issues via DHCP anything under 192.168.0.15. Once you hard-coded the NICs to a static Ip within the reservation range, you'll never have to worry about changing Ip's again for the reserved tabled devices even after reboot.
       In essence, the Netgear DOES NOT and WILL not assign a "static" Ip address just because you entered the info in that reservation table. I hope this helps.

The only devices that need their NICs hard-coded w/ a static Ip are the ones being reserved or in the reservation Ip block. Everything else can be left as DHCP(Router-side) and set to "Obtain Ip address Automatically" on ea of those devices.

Having done further research on the way IP address reservation is used on the DGN2000 router I have now got it working.

I removed all reserved IP addresses and turned off all those devices that might attach to it.  I then turned on device one.  It was assigned IP address 192.168.0.2 using DHCP.  I then reserved this address by adding it to the IP address reservation table using the facility that shows attached devices and their MAC addresses.

I repeated this for each device in turn that I wanted to reserve and IP address.  For each device I turned on, it was allocated the next IP address e.g. 192.168.0.3, 192.168.0.4....

Having completed this I tried rebooting/disconnecting each device I had setup and everything works fine.  Each time a device starts and uses DHCP to retrieve an IP address, it looks up the reserved IP address from the address reservation table and assigns that.  For devices that I didn't set up it assigns the next IP address available "that isn't in the IP address reservation table".  The Netgear is still configured to use the IP range 192.168.0.2 to 192.168.0.254 for DHCP i.e. it "includes" the range of IP addresses setup in the address reservation table.

It may be that I have setup the IP addresses in the address reservation table in ascending IP sequence, whereas before I didn't.  It's hard to believe this was the cause of the problem (if it was).

None of the devices have had static IP addresses set.

I'm not quite sure where The Warlock is coming from but a couple of things you have said don't ring true.  Maybe this is because they are done differently on Netgear:
- "The address reservation feature on the Netgear does not issue addresses within the reservation Ip range".  Not true.  This is the whole point of the address reservation feature - to allocate IP addresses that have been reserved for specific devices.
- "The only devices that need their NICs hard-coded w/ a static IP are the ones being reserved or in the reservation Ip block".  Not true.  I haven't setup any static IP addresses and everything is working fine now.
- "Set you Netgear DHCP server start and ending address as:  Start: 192.168.0.15   End: 192.168.0.254".  Not true.  The DHCP range needs to include ALL IP addresses, whether they are reserved or not.

It appears that maybe The Warlock is coming at this from a different angle: If I had a bunch of devices with static IP addresses, I would want to make sure these IP addresses weren't allocated to other devices otherwise I might get IP address conflicts.  This would be another reason for setting up the address reservation table.  However, I want to use DHCP on the router to control ALL IP addresses.  This is less administration (as I don't have to manually set static IP addresses on each device) and it can be done centrally (I can see at a glance on a single web page what IP addresses each device is expected to be assigned).
