AKS Learn feedback: Conntrack Table default limit not correct

Feedback

Hello, the documentation states the default net.netfilter.nf_conntrack_max is 131072. But we see on our nodes it is actually 262144, which might be due to linux calculations (buckets * 4). Are the defaults mentioned in the documentation actually set or is AKS just using Linux defaults?
