The Connect integration uses bridge networking and iptables to send traffic between containers, but the RedHat family of Linux distros sets some of the kernel tunables this requires to be optimized for VMs rather than containers. We can document this behavior for now and consider better operator feedback for pre-flight checking later.

For #6580
The Connect integration uses bridge networking and iptables to send traffic between containers. But the RedHat family of Linux distros sets some of the kernel tunables we need to be optimized for VMs rather than containers. We can document this behavior for now and consider better operator feedback for pre-flight checking later.
Note that arguably this is something that should get fixed in the upstream CNI plugins, but changing this kernel tunable silently sounds problematic from Nomad's perspective as it would probably break workloads running with the QEMU task driver.
