iptables上如何封ip-ag真人游戏

1、封锁单个ip:  iptables -i input -s ip -j drop

[root@node1 ~]# iptables -i input -s 192.168.1.11 -j drop
[root@node1 ~]# iptables -l
chain input (policy accept)
target     prot opt source               destination
drop       all  --  192.168.1.11         anywhere

2、解封单个ip：iptables -d input -s ip -d ip -j accept

[root@node1 ~]# iptables -d input -s 192.168.1.11 -j drop  # 解封ip: 192.168.1.11
[root@node1 ~]# iptables -l
chain input (policy accept)
target     prot opt source               destination

二、封ip段

1、封ip段： 从123.0.0.1到123.255.255.254的命令

[root@node1 ~]# iptables -i input -s 123.0.0.0/8 -j drop
[root@node1 ~]# iptables -l
chain input (policy accept)
target     prot opt source               destination
drop       all  --  123.0.0.0/8          anywhere

2、封ip段： 从123.45.0.1到123.45.255.254的命令

[root@node1 ~]# iptables -i input -s 123.45.0.0/16 -j drop
[root@node1 ~]# iptables -l
chain input (policy accept)
target     prot opt source               destination
drop       all  --  123.45.0.0/16        anywhere
drop       all  --  123.0.0.0/8          anywhere

3、封ip段：从123.45.6.1到123.45.6.254的命令是

[root@node1 ~]# iptables -i input -s 123.45.6.0/24 -j drop
[root@node1 ~]# iptables -l
chain input (policy accept)
target     prot opt source               destination

drop       all  --  123.45.0.0/16        anywhere
drop       all  --  123.0.0.0/8          anywhere

[root@node1 ~]# iptables -f

[root@node1 ~]# iptables -l input
