the exact iptables command is in format `iptables -w 2 -t nat -N TP_OUT sh`, and seems nftables has different command form. I installed iptables and everything works well, but I still wonder what's `iptables` package status now as it is announced be replaced by nftables. For now I think it's the proxy software's duty to solve this problem.
