How to isolate guest wi-fi network with unmanaged switch?

Question

Computer networks

Network topology star
What we have, a tplink 1043dn router as a gateway with openwrt with dhcp,
then an unmanaged switch from d link hosts are hooked from it (cameras, corporate PCs and laptops, as well as access points from unifi ap ac lite)

Now all hosts and guests go in the same subnet 192.168.10.0/24

The question is: How to raise the 2nd dhcp server and distribute ip addresses from it from another subnet in the guest network on unifi ap ac lite points?
If you raise the 2nd dhcp on the router and hang it on the vlan port, will there be a vlan connection between the router and the unifi access points, provided that there is an unmanaged switch between them and there are still a lot of different hosts in it?

Answer 1

Depends entirely on the switch. There are switches that pass VLANs through themselves, and there are switches that cut off the tag.
Unfortunately, you can find out this information only by typing, since this is usually not written in the documentation for stupid switches.

Answer 2

VLAN make. should work.
with Mikrotik + stupid long switches (usually 16-24 ports) everything works for me
