# Zia Create Firewall Filtering Rule

> Create a ZIA Cloud Firewall Filtering rule that controls network traffic by source/destination IP, country, network application, network service, device trust level, user/group/department, location, and optional time-of-day schedule (Time Interval). Supported actions: ALLOW, BLOCKDROP, BLOCKRESET, BLOCKICMP, EVALNWAPP. Use when an admin asks to 'create a firewall rule', 'block traffic to X', 'allow traffic from Y', 'block country Z', 'restrict access during business hours', or 'add a firewall exception'. This skill creates exactly one Cloud Firewall rule and chains to zia-manage-time-interval when the admin's request includes a recurring schedule.
