This has been a huge limitation for us for a long time, being unable to do leases via DHCP Option82 parameters I saw in RouterOS v7 that User Manager has had an overhaul, i’m wondering if its now possible to somehow use this (or just the base DHCP server) to assign addresses based on either the Cir…

Perhaps you can use Docker on your Mikrotik model to run exactly a instance of a DHCP Server that supports your needs. So you do not need an extra device for this job.

Using the container feature it can be done like this with Kea DHCP for example on RB5009 on ether2 to ether8 /file/edit config/dhcp4.json contents { "Dhcp4": { "valid-lifetime": 4000, "renew-timer": 1000, "rebind-timer": 2000, "subnet4": [{ "subnet": "192.168.88.0/24…

I have no interest in adding a docker DHCP server when the mikrotik server can do it. It needs a few tweaks to do it really well.

[image] damadmai: uld have been much simpler and nicer if the built in DHCP Server allows for matching on circuit-id Nice Solution. Did not know about KEA... Looks nice and fresh. :slight_smile: BTW: Yes Mikrotik shoud add those options to there DHCP-Server.

[image] How to configure "option 82" on the same Mikrotik router? General Since 7.21 it is possible to specify Agent Remote Id and Agent Circuit Id for DHCP leases. These parameters work similarly to Client ID parameter- the server will use the lease for a requ…

Yes! Finally! Just tried this and it works exactly as expected, allowing all MAC address to remain as 00:00:00:00:00:00 and use only the circuit ID or remote ID instead This isn't just about trusting the client device, it massive improves management and scalability. Circuit/remote IDs define where…

DHCP Option 82 circuit/remote ID for server leases in v7?
