Opening the firewall for selected PC's (DMZ)

PC's in side the L AN c annot be ac cess ed fro m the Inte rnet by def ault . The rout er pro tects

the LAN by its Firewall. Some applications do not work properly behind a firewall

because they require unrestricted data flow in both directions. In this case you can

define a so-called demilitarised zone (DMZ) for a PC running such applications. When

you create a DMZ, all requests for a service that come from the Internet will be

forwarded to that PC unless the service has already been forwarded to another PC by

Port Forwarding (see page88).

◆To create a DMZ for a PC, select DMZ in the Virtual server menu.

!

Please bear in mind that the demilitarised PC is no longer protected

against unauthorised access from the Internet and as such could be a

security risk for your network. You should use this option only in

emergency situations.

iYou will find an example of how to create a DMZ in "Practical Tips and

Configuration Examples" on the CD supplied.
