What Working Modes and Protection Mechanisms Does WAF Have?
After you connect a domain name to your WAF instance, WAF works as a reverse proxy between the client and server. The real IP address of the server is hidden and only the IP address of WAF is visible to web visitors.
- Enabled
- Suspended
- Bypassed
- If a proxy is used for the website that is deployed in Cloud mode before it is connected to WAF, the WAF instance cannot be switched to the Bypassed mode.
- The Bypassed mode is unavailable for websites deployed in Dedicated mode.
For more details, see Switching WAF Working Mode.
