Opening the firewall for selected PCs (Exposed Host)
You can set up a client in your local network to be a so-called "exposed host" (DMZ). Your
device will then forward all incoming data traffic from the Internet to this client. You can
then, for example, operate your own Web server on one of the clients in your local net-
work and make it accessible to Internet users.
As the exposed host, the local client is directly visible to the Internet and therefore par-
ticularly vulnerable to attacks (e.g. hacker attacks). Only activate this function if it is
absolutely necessary (e.g. to operate a Web server) and other functions (e.g. port for-
warding) are not adequate. In this case you should take appropriate measures for the
clients concerned.
