Suppose A, B, C three computers, A computer has a network interface (the IP: 192.168.5.10), B
computer has two Ethernet ports (IPl: 192.168.5.11, IP2: 192.168.5.12), C
with a computer a network interface (IP: 192.168.5.13).
Only two cable, to achieve the three ABC any two computers may communicate with each other.
Procedure:
1.A network connection port B 1, C 2 connected to port B of the network
2. The PC B of two network ports "bridge", specifically as follows:
Select two local connection, click the right button click "bridge", as shown below:
Social value bridge IP address 192.168.5.12, as shown below:
With this setting, only one external computer network B port address is 192.168.5.12, ABC case three computers can ping each other between any two, UDP communication may be performed.
