Configuring Firewalls to Allow Tofino™ CMP Traffic
March 2010
The Tofino Central Management Platform (CMP) is a software application program that allows all Tofino Security Appliances (SAs) in a control network to be managed from a single workstation in the plant.
The Tofino CMP may be located anywhere in the network, as long as it is able to communicate with the Tofino SAs that it manages. If any routers or firewalls are located between the Tofino CMP and a Tofino SA in the network, then each router/firewall device must be configured to allow the Tofino CMP traffic to pass through these devices.

This application note shows how to configure a set of firewall rules for the Tofino Firewall to allow the discovery request and reply traffic for the Lantronix line of serial/Ethernet converters.
