An example of both load balancing and CARP

To demonstrate how the concepts introduced might be implemented in a real-world scenario, we will return to the example network introduced in the beginning of the chapter. Some very specific requirements were outlined:

  • We need redundant firewalls, and this requires implementing CARP.
  • Finally, we wanted to introduce some redundancy into our FTP server, and have at least two separate servers. This requires implementing server load balancing.

Assume that we have a LAN network for local traffic, and also assume that we have a separate DMZ network for the FTP server.

Assume we have a subnet of for the LAN network, and a subnet of for the DMZ network. The FTP server's IP address ...
