Sorry, during the week I didn't have too much time for experimental studying. Today I had time to get a headache. I tried all variant from the configuration guides and CCNA / CCNP cert books, without success. Later on I had the idea it may have got some trick as the previous devices that have webgui. So I restored the original homelab config with L3 switch and OSPF routing with the ISP router and started to setup the vlans by webgui. When I made the SVIs in one menu then pair them up with the same vlans and interfaces it started to work without any hassle.
Here are the extra commands that the gui insert into my config:
ip dhcp use subscriber-id client-id
ip dhcp subscriber-id interface-name
ip dhcp pool LAN - address 172.16.10.5 client-id "Gi0/2/0" ascii
ip dhcp pool WIFI - address 172.16.20.5 client-id "Gi0/2/2" ascii
interface GigabitEthernet0/2/0 - 0/2/2
ip dhcp relay information option server-id-override
ip dhcp server use subscriber-id client-id
interface Vlan 20 / 30
ip dhcp relay source-interface Vlan20 / Vlan30
And that's all, everything else remained the same.

So it is as usual, following the configuration guide led to instant fail. Now I go to sleep and tomorrow I will find out what these command are as I have never seen them before either my studies or the customers' configs.
