When we use VMware virtualization software, we often find that they can all Virtualize a nic, which seems amazing. In fact, in Linux, there are two kinds of virtual backup, point-to-Point device in Tun. Tap indicates an Ethernet device. It is used as a virtual NIC Driver. Program Data receiving and sending does not directly deal with the real network card, but is transferred through the user State. In Linux

Recently, we need to use the Linux iptablesNAT function to map ports, but the interface machine only has one Nic. To achieve both Intranet access and Internet access, we need to use the methods described below: 1. Assume that the Intranet IP address is address192.168.100.6netmask?255.255.0gateway192. We recently used the Linux iptables NAT Function to map ports,However, the interface machine has only one N
