Hi, Is it possible to mordernize the following iptables rules?

-A INPUT -i eth1 -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
-A INPUT -i eth1 -p icmp -m icmp --icmp-type 8 -j ACCEPT
-A INPUT -i eth1 -p icmp -m icmp --icmp-type 0 -j ACCEPT
-A INPUT -i eth1 -p tcp --dport 22 -j ACCEPT
-A INPUT -i eth1 -p udp --dport 51820 -j ACCEPT
-A INPUT -i eth1 -j NAME_1


-A FORWARD -i eth1 -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT
-A FORWARD -i wg0 -o wg0 -m conntrack --ctstate NEW -j ACCEPT

-t nat -A POSTROUTING -s 10.3.253.0/24 -o eth0 -j NAME_2 The word "--icmp" should not appear in your response.
