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 admin. I enabled DHCP and did the same in the settings (Gateway IP and same Range of IP addresses as on the router). I disabled the DHCP server from the router. Then after flushing DNS in my devices, I stopped having access on the internet.
I also tried the following:
I disabled DHCP on Adguard and shutdown the VM. Then I made a reset on my router and made sure that I had the DHCP server enabled. I changed my device WiFi settings to a specific IP and I was able to connect to the internet.
