IpTablesParserException Unknown option: "--random-fully"

[wlclass]

Thank you for a great job.👍
When I tested it on Ubuntu 20.04.3 LTS \ iptables v1.8.4 (legacy) .

var sys = new IpTablesSystem(new LocalFactory(), new IPTablesBinaryAdapter());
var chain = sys.GetChain("nat", "PREROUTING", 4);

I got an error :

IPTables.Net.Exceptions.IpTablesParserException: Error parsing rule:  -A KUBE-POSTROUTING -m comment --comment "kubernetes service traffic requiring SNAT" -j MASQUERADE --random-fully
