I currently have 2 Astaro boxes. The first, firewall A, is our main router and also spam filter. The second, firewall B, serves only as an addtional spam filter. Each has a seperate public IP with MX records configured for firewall A as priority 10 and firewall B as priority 20. Firewall B does an awesome job at stopping spam - it stopped 15,000 of 16,000 bogus emails. Firewall A, on the other hand, stopped only 10,000 of 24,000 bogus emails. Does anyone know what could possible be going on here? Both firewalls were configured from the same backup, so the settings are identical. CPU usage and Memory usage are both low to medium. I attached screen shots of the crazy differences.
