WRT54G and DHCP Micro-Management

    I am a proud owner of a rev 4 WRT54G, currently running DD-WRT v23 mini. So far so good but now need to figure out some DHCP management options.

    I have a bunch of legacy devices in my network. At the moment they are all set to get IP address from DHCP, and many can't even be hardcoded to a completely user selectable fixed address. With my current router DHCP server I can map any given MAC address to always have the same IP address. Makes it much easier to access the web interfaces of the devices.

    Is there a way to do this with any WRT54G firmware? I have tried DD-WRT and HyperWRT so far, no luck.

    And if this is not possible can anyone answer the following question: If I set the DHCP to accept 30 connections starting at XXX.XXX.1.100 does it mean it will only use 100 - 129 for DHCP and I can safely have XXX.XXX.1.132 set as a fixed address for a device?

    TIA,

    Jarmo

    I'm doing it just fine in HyperWRT. Download the Tofu 11 build, then look under the "Static DHCP/Domain" subsection of the basic setup tab.

    I'd have to imagine the Thibor build has it, too.

    That is correct.

    Works Fine on Both

    Thank you both, I now have WRT54G happily up and running (Tofu) after I first figured out how to install it on V4 (size limitations, have to install another firmware first).

    I am using a mix of both methods for mapping those devices I need http-access to. So far it has been a smooth ride with no complaints.

    BR,
