balenaOS 3.1.1 + net.ipv4.icmp_echo_ignore_broadcasts: 0 = error

Product support balenaOS
1

Hi

I have several devices running on balenaOS v2.x.x (e.g, balenaOS 2.89.15, balenaOS 2.113.15) with the following config in the docker-compose

    sysctls:
     net.ipv4.icmp_echo_ignore_broadcasts: 0

and it’s working fine.

However, running same docker-compose file at a device with balenaOS 3.1.1 produces the following error:

Error response from daemon: OCI runtime create failed: runc create failed: sysctl “net.ipv4.icmp_echo_ignore_broadcasts” not allowed in host network namespace: unknown
Error: failed to start containers: 171d93434c8a

Is there a way to solve this?
