Cannot make the DHCP Server of Adguard Home to work

I bought a mini-pc to start experiment a little bit with homelab. My plan is to setup Home Assistant, Adguard Home and Nextcloud as a starting point. All those, through proxmox. The router I have is locked from the provider and I cannot add a custom DNS. The router is also locked on VOIP and I cannot replace it. I have 2 options. Either add a second router to bridge with the first and connect all my devices there OR disable the DHCP server from the router and use the one from Adguard. I enabled Adguard Home, add on the VM network the static IP and as the Gateway IP the IP I had in my router ad
