Firewalls

Firewalls can be configured at various layers of the MPF architecture.

Firewalls in front of a MobileFirst Server use the typical configuration.

Special attention must be given to a firewall layer between the MPF servers and the MPF database.

• MobileFirst Server employs database connection pooling. Firewalls may detect idle database connections and terminate them resulting in unexpected behavior.

• Firewalls limit the number of connections allowed. This is done to prevent Denial of Service (DoS) attacks. However, with multiple clustered MobileFirst Server instances, the number of connections might be higher than usual.
