An example configuration – 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.
- We wanted to balance outgoing traffic across two WAN connections, which requires gateway load balancing.
- 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. Prior to implementing any of the ...
