linux iptables 修改本机生成的网络数据的目的地址（DNAT）

使用netfilter/iptables，命令如下：

echo "1" > /proc/sys/net/ipv4/ip_forward
iptables -t nat -A OUTPUT -d 修改前的目的地址 -j DNAT --to 修改后的目的地址

OUTPUT:表示本机生成的网络数据


参考(man iptables):
nat:
                  This  table  is  consulted when a packet that creates a new connection is encountered.  It consists of three
                  built-ins: PREROUTING (for altering packets as soon as they come in), OUTPUT (for altering locally-generated
                  packets before routing), and POSTROUTING (for altering packets as they are about to go out).
