    Today I will show you the iptables rules I set on my main personal computer, with detailed comments about why I came to use these rules after several years of Linux desktop usage. The rules I use now have been simplified as much as I could and are based on common rules and advice that can be found on the network and also on input I got from experienced network administrators. I So here they are:

    # iptables -v -L
    Chain INPUT (policy DROP 0 packets, 0 bytes)
     pkts bytes target     prot opt in     out     source               destination
     663K  905M ACCEPT     all  --  any    any     anywhere             anywhere            state RELATED,ESTABLISHED
      105  6300 ACCEPT     all  --  lo     any     anywhere             anywhere
        0     0 ACCEPT     icmp --  any    any     anywhere             anywhere            icmp destination-unreachable
        0     0 ACCEPT     icmp --  any    any     anywhere             anywhere            icmp time-exceeded
        0     0 ACCEPT     icmp --  any    any     anywhere             anywhere            icmp source-quench
        0     0 ACCEPT     icmp --  any    any     anywhere             anywhere            icmp parameter-problem
        0     0 DROP       tcp  --  any    any     anywhere             anywhere            tcp flags:!FIN,SYN,RST,ACK/SYN state NEW
    
    Chain FORWARD (policy DROP 0 packets, 0 bytes)
     pkts bytes target     prot opt in     out     source               destination
    
    Chain OUTPUT (policy ACCEPT 0 packets, 0 bytes)
     pkts bytes target     prot opt in     out     source               destination
