OUI-prefix (vendor wildcard)

Networking Solutions Question

Question:

Does Teltonika natively support OUI-prefix (vendor wildcard) MAC matching in the dnsmasq DHCP server — that is, the ability to match all MAC addresses starting with a specified prefix (e.g., 00:20:4A:*) to a tag or pool, in a way that:

  1. Is configured through UCI (and is therefore manageable via the WebUI or via RMS configuration templates),

  2. Persists across reboots and firmware upgrades, and

  3. Is officially documented and supported by Teltonika Networks.

The functionally similar upstream dnsmasq directive would be:

dhcp-mac=set:trusted,00:20:4A:*
dhcp-ignore=tag:!trusted

We understand this directive exists in standard dnsmasq. Our question is specifically whether it is exposed and supported in Teltonika’s UCI / WebUI / RMS configuration model, or whether the only officially supported mechanism is per-MAC static leases (one MAC to one IP).

If natively supported:

  • Which firmware versions support it?

  • Is configuration done via UCI (which dhcp UCI section / option), via WebUI, or both?

  • Can it be deployed via RMS configuration templates?

If not natively supported:

  • Is it on the product roadmap?

  • Is manual injection of dhcp-mac directives into the dnsmasq configuration (e.g., via SSH editing of /etc/dnsmasq.conf or via a custom config snippet mechanism) officially supported, or is it considered out-of-scope for support and likely to be overwritten on firmware updates?

The purpose of confirming this is to avoid promising functionality to our customer that may not be sustainably supported. A clear “supported / not supported” answer is more valuable to us than a workaround that may break on the next firmware release.

Thank you in advance for your time.
