Can I use a FreeBSD router to configure Snort?

Q: My FreeBSD router has two network interface cards: one connecting data from the data center and the other connecting to a 24-port switch. In this case, can I install a tool similar to Snort? If yes, what configurations will I need?

A: You can run Snort in the above environment, but this is not necessary. As you described, I am most worried about using the FreeBSD server and making it work in three ways: Server, router, and intrusion detection system IDS ). This is fine in the bootstrap environment, but if you are running a data center that uses the 24-port switch, I do not encourage this.

I suggest you use specific devices on the network to perform their respective functions. It is best to use a dedicated router to complete routing. It is better if you can purchase a hardware router than creating a route on the FreeBSD server. Similarly, you should use a separate device as the intrusion detection system IDS) sensor.

This can minimize the complexity. Complex network environments increase the chance of errors and make it more difficult to find network faults.
