SDN stopped forwarding

[cyruspy]

Hello!,

What's the SDN logic to enable forwarding?. After an upgrade from 8 to 9 my overlay network is not working anymore. Just checked and
net.ipv4.conf.all.forwarding is disabled.

I don't recall its specific configuration in the past, but I don't have evidence of the working configuration being different.

If you enabled it via /etc/sysctl.d - this has been deprecated with Debian 13 [1]. You'd need to move it to /usr/lib/sysctl.d/

I didn't add the config explicitly, it came from the SDN setup somehow.

For the time being I fixed it adding the option by hand, not sure if that is the correct approach.

Thanks.
