This guide applies to: TL-R470T+ v6 or above, TL-R480T+ v9 or above, TL-R600VPN v4 or above, TL-ER5120 v3 or above, TL-ER6020 v2 or above, TL-ER6120 v3 or above |
You can preset certain preferences, such as IP groups, time ranges, IP Pools and service types. These preferences will appear as options for you to choose when you are configuring the corresponding parameters for some functions. For example, the IP groups configured here will appear as options when you are configuring the effective IP addresses for functions like Bandwidth Control, Session Limit , Policy Routing and so on.
Once you configure a preference here, it can be applied to multiple functions, saving time during the configuration. For example, after configuring a time range in the Preferences > Time Range > Time Range page, you can use this time range as the effective time of Bandwidth Control rules, Link Backup rules, Policy Routing rules, and so on.
IP groups configured here can be used as effective IP addresses for multiple functions like Bandwidth Control, Session Limit , Policy Routing and so on.
To complete IP Group configuration, follow these steps:
1)Add IP address entries.
2)Add IP address entries to an IP group.
