Docker Install blocks local network access

I’m trying to setup firezone in AWS in order to access other services hosted in the same VPC, however I’ve run into a networking problem.
When the docker container is started, both the firezone host and all connected clients lose the ability to ping other resources on the same subnet - but can still access the internet. After stopping the firezone containers the host can once again access other servers on the same subnet.

Is there something I’m doing wrong or need to configure specifically for this application?
The homelab scale equivalent is running firescale on a Raspi and needing to allow clients to access other devices on the local network.
Thanks in advance
