Settings in this group simplify the configuration of access to this computer's services from the trusted zone. Many of them enable/disable pre-defined firewall rules. You can edit allowed services in Advanced setup (F5) > Network protection > Firewall > Advanced > Allowed services.

Allow remote desktop in the Trusted zone—Enables connections via Microsoft Remote Desktop Protocol (RDP) and allows computers in the Trusted zone to access your computer using a program that uses RDP (for example, Remote Desktop Connection).

Configure zones

A zone is a collection of network addresses that create one logical group of IP addresses, useful when reusing the same set of addresses in multiple rules. Each address in a given group is assigned similar rules defined centrally for the whole group. One example of such a group is a Trusted zone. A Trusted zone represents a group of network addresses that are not blocked by the Firewall in any way.

To add a trusted zone:

1.Open Advanced setup (F5) > Network protection > Basic > Zones.

2.Click Edit next to Zones.

3.Click Add, type in a Name and Description for the zone, and type a remote IP address in Remote computer address (IPv4/IPv6, range, mask).

4.Click OK.
