How to assign static LAN IP

[gatorback]

I would like to assign static LAN IPs to certain MAC addresses. I've done this with DD-WRT and imagine that it can be done with OpenWRT. I could not find an example. If you have done this before please provide an example. Thank you.

What router? What firmware?

Usually in the LAN config pages.

Good question: RT-AC87U with Merlin V. 378.55

lan menu > dhcp server. scroll down.

Is it possible to do this from the command line? I would like to be able to program routers with devices to be pinned to static LAN IPs.

You can add them to dnsmasq itself using the the /jffs/configs/dnsmasq.conf.add file. Just add/remove entries llike this:

dhcp-host=aa:bb:cc:dd:ee:ff,192.168.111.50

and then restart dnsmasq:

service restart_dnsmasq

@Calriso: very nice!

And, if you want to give it a new name....

dhcp-host=aa:bb:cc:dd:ee:ff,192.168.111.50,newclientname

Is there any advantage to assigning IP addresses through the command line?

I have always done it the first way through LAN>DHCP>IP assignment and it works for me. The only problem I have with that is that I have to enter the IP assignments on every router individually if I want them the same. Doing a hard factory reboot requires that I have to enter the IP assignments manually again. It is somewhat tedious when you have 40+ assignments to do on multiple routers. Could this be done with a script that I only have to do once and can copy to each router without having to manually reenter it each time?

Or, if a gadget is already assigned a name in its OS, simply:

• dhcp-host=android-fone,192.168.111.50

where android-fone is the gadget's hostname perhaps automatically assigned by its OS.

If not sure what name an OS assigns, we could find it in System Log > DHCP Leases page in Asuswrt-Merlin. While you're at it (and if possible), re-assign a user friendly name to your gadget in its OS..

Thanks, I didn't catch this thread when it was posted. A very useful utility.
