debian7配置iptables
vim /etc/iptables.rule
文件内容如下
*filter
# Allows all loopback (lo0) traffic and drop all traffic to 127/8 that doesn’t use lo0
-A INPUT -i lo -j ACCEPT
-A INPUT ! -i lo -d 127.0.0.0/8 -j REJECT
# Accepts all established inbound connections
-A INPUT -m state –state ESTABLISHED,RELATED -j ACCEPT
# Allows all outbound traffic
# You could modify this to only allow certain traffic
-A OUTPUT -j ACCEPT
# Allows HTTP and HTTPS connections from anywhere (the normal ports for websites)
-A INPUT -p tcp –dport 80 -j ACCEPT
-A INPUT -p tcp –dport 443 -j ACCEPT
# Allows SSH connections for script kiddies
# THE -dport NUMBER IS THE SAME ONE YOU SET UP IN THE SSHD_CONFIG FILE
-A INPUT -p tcp -m state –state NEW –dport 22 -j ACCEPT
# Allow ping
-A INPUT -p icmp -m icmp –icmp-type 8 -j ACCEPT
# log iptables denied calls (access via ‘dmesg’ command)
-A INPUT -m limit –limit 5/min -j LOG –log-prefix “iptables denied: ” –log-level 7
# Reject all other inbound – default deny unless explicitly allowed policy:
-A INPUT -j REJECT
-A FORWARD -j REJECT
COMMIT
测试这个脚本，iptables-restore < /etc/iptables.rule
如果发现iptables-restore v1.x.x: no command specified的错误，就把上面的脚本里面的空行全部删除，然后再重新回车添加
建立开机启动，vim /etc/init.d/start-iptables
#! /bin/sh
### BEGIN INIT INFO
# Provides: custom iptables
# Required-Start:
# Required-Stop:
# Default-Start: S
# Default-Stop:
## Short-Description: custom iptables
### END INIT INFO
/sbin/iptables-restore < /etc/iptables.rule
chmod +x /etc/init.d/start-iptables设置执行权限
rcconf添加这个脚本开机启动
