“Single LAN” VPN
The above figure gives an example of a “Single LAN” VPN.
The client PC (with IP address 192.168.1.X) can connect, just as an example, to the first Z-PASS2 by using its
192.168.10.154 IP address and to the PLC in the Z-PASS LAN by using its local IP address 192.168.10.102.
Also, two devices which lie in two different LANs of the same VPN network (e.g.: 192.168.10.101 and
192.168.20.102) can connect to each other, again using their local IP addresses.
To let this scenario work correctly, an essential rule must always be followed: the Z-PASS LANs and the PC
LAN shall have different and not colliding subnets; so, in the above figure, the following subnets allocation
