Opening the firewall for particular PCs (DMZ)
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 PCs running such applications.
◆ In the Firewall menu, select DMZ.
◆ The Public IP address has as the first entry the router's Public IP address . If you have
other public IP addresses, enter them under the router address.
◆ In Client PC IP address enter the IP addresses of the PCs you want to exclude from
the firewall functions.
◆ To apply the settings click on APPLY.
i
When setting up DMZ PCs make sure that the PCs always have the same
IP address. This means:
◆ the IP addresses must be static (see "Practical Tips and Configuration
Examples") or
◆ the Lease time for dynamic address assignment must be set to
Forever (see page 69).
!
Please bear in mind that these PCs are 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.
