select dhcp network/pool/server based on client identity or option?

RouterOS General

I have lots of wireless clients using the same SSID. I want to pass different networks(gateway/dns) to different classes of clients. At the moment I do this by fixing the lease to static and dialing in the network ip.
is there way to do it automatically based on client’s dhcp configuration?

You can link a vendor id to an address pool, but that may not be flexible enough.

You can use wireless access list to map the client MAC address to a VLAN (with its own subnet & DHCP server), but with contemporary mobile phones using random MAC addresses it is not much useful any more.

You can also use wpa2-enterprise authentication mode (where the wireless clients authenticate to a RADIUS server by username and password), and it should be possible to let the RADIUS server provide the VLAN ID as well, but I haven’t tried that myself yet.

the devices using random mac address will go to the “default” net and that’s OK for my purpose. Point is how to mark the “known” devices to separate nets.
I’ve got several wifi APs and don’t want to assign vlans for now as it is too much work compared to my current primitive solution

It’s not a big difference whether you let an /ip dhcp-server lease item refer to MAC address (or, more-precisely, client-id) or an /interface wireless access-list or caps-man access-list item. With DHCP lease, you can use also the vendor ID to choose a pool; with /caps-man access-list (not with /interface wireless access-list), you can use MAC address mask, but I guess it doesn’t help much as it is similarly rigid like the DHCP vendor-id.

So the only advantage of wireless access list is that you can segment the network using VLANs rather than having all subnets in the same L2 network. If VLANs seem too complicated to you, RADIUS authentication is even more complicated, so not an option either.

One thing you may have missed, in a static DHCP lease, you can still use a pool rather than a particular IP address if you find that useful. But you still need one lease per each “special” client.

oh, thank you, that’s convenient! didn’t notic the drop box.
