Hi Ken,

What interface are you going to use to connect to esxi? when you install esxi you would see 4 interfaces under Configure Management Network ->network adapters. vmnic 0 and 1 are internal interfaces that connects to the router and vmnic 2 and 3 are external front panel interfaces which is marked as GE2 and GE3. You could use any of those interfaces to connect to your esxi host from your client machine via vSphere Client. but if you use vmnic 0 or 1, you would need additional configuration on the router since it is going through the router. but if you use vmnic 2 or 3 it is rather straight forward.

In your other post, i see you are trying to get the CIMC up and running. To Connect to cimc you can use internal or external interfaces under shared-lom mode or dedicated interface (marked as "M" on faceplate) under dedicate mode. The given configuration in the reply uses internal interface (imc access-port host console). For more information please refer "Configuring CIMC access" section of the "Installation and Configuration Guide" which is posted on knowledge Base.
