A Self IP is an IP assigned to the F5 that is usually not used by load balanced traffic. Routing Though the in-line F5īelow, we have a diagram of a typical in-line setup where the F5 has a default route to the upstream switch and the servers have a default route to the F5 Self IP on the internal VLAN.

If you choose in-line, the next section will show you how to get non-load balanced traffic through your F5. If you are debating which method to use, choose the method that is best for your environment. Neither stick or in-line topology is wrong. The picture below shows an example of server traffic – If you see a model where the traffic throughput specification is much larger for the L4 traffic than the L7 traffic this is one of the models. Most of the time this is not a huge volume of traffic (except maybe backups) and many of the larger F5s have an FPGA to accelerate the L2-L4 traffic so as not to burden the CPU. However, now all host traffic passes through the F5 such as database, DNS or any other non-load balanced traffic going to or from the server. This method preserves the source IP which is one of the best methods for non-HTTP applications and will also ease troubleshooting. With the in-line method the servers are behind the F5 and the F5 becomes the default gateway for the servers.
