** Observations **
**1. Failover technique (Active-Passive)**
* Your approach to use static IP addresses and bridge interfaces is a good one. This will allow for seamless communication between master hosts.
* The trick of exposing the "bridge" interface to the world with a statically configured IP address is clever.
**2. Load balancing (Active-Active)**
* Load balancing is an excellent way to distribute traffic across multiple servers, ensuring that no single point of failure exists.
* Using an Active-Active setup will allow for more efficient resource utilization and improved scalability.
Some suggestions:
1. **Consistency**: Consider using a consistent naming convention throughout your outline (e.g., use "Failover" instead of "Failover technique").
2. **Clarify the role of the WAN router**: It might be helpful to explicitly mention how the WAN router is involved in this setup and what its role is.
3. **Highlight security considerations**: Since you're exposing interfaces to the world, make sure to emphasize any relevant security measures that need to be taken (e.g., firewalls, access controls).
2. **Failover (Active-Passive)**: Your setup remains the same as before - master hosts communicate with each other to detect failures, and bridge interfaces are used for seamless communication.
**New Information**
1. **Load Balancing (Active-Active)**: No changes here; you're using a load balancing approach to distribute traffic across multiple servers.
2. **DDOS Protection**: You've implemented a custom script called `fwspoof` that uses `tcpdump+fwspoof` for DDOS protection. This is a good measure to prevent unwanted HTTP server attacks and CPU usage spikes.
**Security Measures**
1. **FWSpoof (DDOS Protection)**: Your custom script, `fwspoof`, seems to be an effective solution for DDOS protection.
2. **FWTrash (Log Analyzer)**: Another custom script you've created, `fwtrash`, appears to block unwanted programs that scan computers and data.
**Other Observations**
1. **External Feedback**: You've linked to an external page where AIIA (presumably another AI/IA entity) provides feedback on your network architecture.
2. **Custom Scripts**: It's great that you're developing custom scripts for specific security needs, such as `fwspoof` and `fwtrash`. These will likely improve the overall security posture of your network.
Keep up the good work! Your high-availability setup is shaping up to be a robust and secure solution.
