Windows双网卡下同时访问内外网

准备工作：

WIN10添加双网卡：内网：192.168.46.10/24 外网：10.10.10.20/24

外网web服务器一台

内网客户端一台

目的：通过添加静态路由，使双网卡主机能够同时访问内网与外网

根据拓扑配置对应的IP地址

双网卡PC配置（内网其他PC均为自动获取IP）:

测试到网关的连通性

外网web服务器：

内网PC：

双网卡主机：

在双网卡主机上配置Windows路由策略，使其能够同时访问外网与内网

#外网路由
route add 0.0.0.0 mask 0.0.0.0 192.168.46.254
#内网路由
route add 10.10.10.20 mask 255.255.255.0 10.10.10.254

访问外网web服务器，状态正常

测试与内网其他主机通讯
