    • Subnet addresses. The network rule controls network packets sent and/or received by remote computers with IP addresses associated with the selected network type: Trusted networks, Local networks, or Public networks.
    • Addresses from the list. The network rule controls network packets sent and/or received by remote computers with IP addresses that can be specified in the list below using the Add, Edit, and Delete buttons.
