Hi,

I'm looking for a ADSL modem/router/switch/wireless box that has DHCP IP reservation ie where you can map a MAC address to an IP address so that the DHCP server always assigns the same IP address the MAC address.

There are half a dozen or so routers that have the hardware features that I want, but unfortunately the manufacturers don't publish very much information about the firmware features.

The models I've found that are locally available are:

DLink DSL-G604T
Linksys WAG200
Belkin F5D7633au4A, F5D7230AU4
Netgear DG834G
3Com 3CRWDR101A-75
CNet
CAR-854
DSE XH9950 - doesn't do it

Can someone who owns one of these, or a similar locally available device, please let me know if it has the DHCP IP reservation feature?

Thanks
Glenn

Hi there
I have the Netgear DG834G and it is the best router we have ever has. it ha never missed a beat and the web configuration is easy to use.
it does reserve the ips depending on the mac address's and i find this extremely handy on our network.

In general I have found that routers that let you register fixed IPs against MAC's will not route to IPs that are not registered to it, either via DHCP or fix notifiation. Routers that dont offer the ability to register fixed IPs against MACs will happily route to any LAN IP address (assuming its within the subnet and does not clash with any DHCP server offered address). Either way they work.

As such the Belkin does not offer a fixed IP/MAC register, but will happily route to an address not supplied by its DHCP server. I cannot comment on the D-Link604 but other D-Link routers I have used will only route to IPs supplied by its DHCP server or registered in the fixed IP table.

AllNightNerding thanks for the reply on the Netgear router. I just realised that the other feature I need is WDS and the Netgear kit doesn't do that (according to their knowledge base and my experience with a WGR614).

Cyril, thats interesting about the routers only routing to their own addresses and is potentially going to be an issue for me since I have one machine that I'd like to use a static IP with and one that I'd like to have a reserved DHCP address. The others would be normal DHCP.

Do you know if the DLink gear does WDS?

I dont know if I made my point clear, you can use static IP's that is no issue, the issue is, from my observation, routers that offer a static ip table for you to make entries dont seem to support static ips that dont exist in that table, and routers that dont have a static ip table for you to make entries in dont care if you have setup static ip's and will happly route to them without knowledge, just dont cross static and dynamic address spaces (obvioulsy).

Eitherway all domestic NAT routers will happily let you have static IP's in the LAN and route to them, some need to know the address, some dont care.
