In Part 1 we looked at the deployment of the NSX Edge load balancer in One-Armed/Proxy mode.

In-Line/Transparent Mode

In this second post we take a look at the alternative load balancer mode – In-Line/Transparent mode. First of all, unlike the One-Armed/Proxy mode, In-Line load balancers require two logical interfaces (LIFs); one Uplink LIF (connected to either a DLR or upstream Edge) and one Internal LIF. The Internal LIF is directly connected to the network segment housing the back-end servers requiring load-balancing. In addition to this (and unlike the One-Armed/Proxy load balancer), In-Line load balancers are required to act as the default gateway for all back-end servers.
