configuring either Virtual Servers or DMZ.
The main difference between Virtual Servers and DMZ is that
•
With Virtual Servers user can open a specific port for the external users and the
traffic designated to this <Public IP>:<port> will be rerouted to the Server on his
LAN Side.
•
In case of DMZ any connection initiated by external host/s to the <Public IP>will be
rerouted to the PC on his LAN side.
