9) Test the tunnel
We'll use ping to check that everything is running ok. First, try pinging the OpenVPN router LAN IP address (the default is 192.168.1.1). It should respond. Next try to ping the IP address of a LAN machine. In my test case, the Win 8.1 LAN computer was at 192.168.1.149. The screenshot below shows that the OpenVPN configuration provided connection to LAN clients.作者: 角色 時間: 2018-2-18 20:31
根据我回看我给你的Link
TUN: 两个IP 段不一样(Router and OpenVPN)估计这个需要输入IP地址才能进去。
TAP: 两个IP段一样(OpenVPN 跟 Router IP pool)
"A TAP device is a virtual ethernet adapter, while a TUN device is a virtual point-to-point IP link." [1]
有的路由器不用TAP or TUN这些术语,他们会用(特别在quick set mode)
TUN:ip / internet + local network (will be different from the router network segment)
TAP : ethernet / local network (some routers automatically use the router DHCP IP pool, or you have to set by your own, i.e. the same network segment as the router IP network segment)
