iptables

  • 删除NAT表规则

使用root：

  1. iptables -t nat -L -n --line-numbers

输出：

  1. Chain PREROUTING (policy ACCEPT)
  3. num  target     prot opt source               destination         
  7. Chain POSTROUTING (policy ACCEPT)
  9. num  target     prot opt source               destination         
  11. 1    MASQUERADE  all  --  10.3.0.0/16        !10.3.0.0/16        
  15. Chain OUTPUT (policy ACCEPT)
  17. num  target     prot opt source               destination

删除POSTROUTING下的num id为1的规则

  1. iptables -t nat -D POSTROUTING 1
