Kea-dhcp4,problem. No connection when assigning a static IP to proxmox lxc

[av8r]

backstory;
I've set up Scanopy to help map my network, and in doing so I had to spin up one LXC container on each VLAN. It works as intended if I let OPNsense hand out dynamic IP to each LXC, but as soon as I give it a static IP I loose connection immediately. I cant ping anything, and each deamon cannot connect to the Scanopy server.

I have the correct firewall rules. this is driving me nuts. any help would be greatly appreciated.

My ranges are i.e. 192.168.20.100-192.168.20.200. on each VLAN. I would like to give all the different LXCs .21 octa. thats when the trouble begins. any number I give it below .100 ends in connection loss. but when OPNsense hands out a i.e. .101 everything works as expected.

I am guessing you have got a setting similar to "If the IP Address is not in the DHCP Leases Database then refuse any connectivity to the Client" Enabled somewhere ??

Thank you for the reply, sounds like you could be into something. But it only happens on LXC devices. Do you have any tips on where to start looking for a setting like that?

Did you set 192.168.20.21/24 and also set the gateway correctly (e.g. 192.168.20.1) for the LXC? Miss that and it won't work - basic stuff, you know.

Yes sir, everything on Proxmox LXC is correct. When I disable firewall in settings it works as intended.
I have the daemon ip's in the alias and have the ALLOWED to reach the server IP as well.
