Can't seem to get a static IP to take on one of my containers. I made sure the IP is not in use and I added etho and vmbr0, selected static and put in 192.168.111.80/24 and a gateway of 192.168.111.1 (my ASUS router). When I restart it, it pulls a DHCP address. I even tried adding a reservation for that specific address (the DHCP one) and when I reboot the host proxmox, it pulled a DIFFERENT DHCP address.

Not sure what is going on here.....any help would be much appreciated!
 
What distribution is running in the container?

Can you please provide the output of pct config <container-id> on the host and ip addr inside of the container?

For ostype: unmanaged containers you need to configure the IP inside the container.

Based on the hostname I'm guessing you are running OpenWrt, so you would have to modify /etc/config/network
