The front net.ipv4.tcp_max_tw_buckets is a tune of 6000, in the web stress test, the System log Mad Report:

Kernel:TCP:time Wait Bucket table overflow

So I changed it directly to 65536.

If the Discovery report:

Error: "Net.bridge.bridge-nf-call-ip6tables" is an unknown key

Error: "Net.bridge.bridge-nf-call-iptables" is an unknown key

Error: "Net.bridge.bridge-nf-call-arptables" is an unknown key

Just load the bridge module and you can:
