Hi @SkywalkerIsNull 

As for the frequency of downloading the rule sets to the IDS/IPS capable routers, TP-Link typically releases updates periodically to ensure that the routers can effectively detect and prevent the latest threats. However, the specific update frequency may vary depending on different product models and security situations. Generally, users can check for updates through the router's management interface or the official TP-Link support website.

Regarding loading your own rule sets or pointing the router to other rule sources such as the Proofpoint Emerging Threats Rules, TP-Link routers are designed to use the rule sets provided by TP-Link. Loading third-party rule sets or pointing to external rule sources may not be supported to ensure the stability, compatibility, and security of the router. It is recommended that users use the official rule sets provided by TP-Link for the best security protection.
