This note is going to demonstrate how to limit Internet access for a specific time interval by an IP filter. Assuming the staffs IP range is 192.168.1.11~192.168.1.100, and they are allowed to access the Internet on 7:00~8:00, 12:00~13:00 and 17:00~20:00.
1. Go to Firewall>>Filter Setup>>IP filter and click Add
2. Click Add in the Group we just created.
3. Create Time Objects for the above periods, the intervals between them need to be blocked, which are 8:00~12:00, 13:00~17:00 and 20:00~7:00
4. Create IP Object of staffs, so this rule will only apply to the defined IP range.
