I have 5 VM's : VM-A,VM-1,VM-2,VM-3,VM-4 I using wireguard to connect VM-A to all other VM's. The traffic transfer rate is around 200Mbps. All the VM's have 5gbps network. But the CPU is rising to 95%. In this the softirq rises to 60%

I guess it is due to using iptables NAT commands

iptables -t nat -I PREROUTING -i ens3 -p udp --dport 9100 -j DNAT --to 192.168.150.2
iptables -t nat -I PREROUTING -i ens3 -p udp --dport 9101 -j DNAT --to 192.168.151.2
iptables -t nat -I PREROUTING -i ens3 -p udp --dport 9102 -j DNAT --to 192.168.152.2
iptables -t nat -I PREROUTING -i ens3 -p udp --dport 9103 -j DNAT --to 192.168.153.2

Is there any other way which can be used instead of iptables which can lower the CPU usage?
