40 1. You can add the DNS server to the target machine using following commands:
41 sudo iptables -t nat -A OUTPUT -p tcp -d 192.168.211.211 --dport 53 -j DNAT --to-destination $CLUSTER_IP:$DNS_PORT
42 sudo iptables -t nat -A OUTPUT -p udp -d 192.168.211.211 --dport 53 -j DNAT --to-destination $CLUSTER_IP:$DNS_PORT
43 sudo sysctl -w net.ipv4.conf.all.route_localnet=1
44 sudo sysctl -w net.ipv4.ip_forward=1
45 2. Update /etc/resolv.conf file with nameserver 192.168.211.211 entry on your target machine
