解决方法
我建议抓一个防火墙配置工具,比如
Firestarter,然后从那里开始.不过,这里有一些基础知识.
@H_301_10@#Flush existing rules
iptables -F
# Set up default DROP rule for eth0
iptables -P INPUT DROP
# Allow existing connections to continue
iptables -A INPUT -i eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT
# Accept everything from the 192.168.1.x network
iptables -A INPUT -i eth0 -s 192.168.1.0/24 -j ACCEPT
# Allow connections from this host to 192.168.2.10
iptables -A OUTPUT -o eth0 -d 192.168.2.10 -j ACCEPT
