VSA - using a different subnet than the hosts, and in a closed network

Hi there,

I am working on deploying a VSA install, where the physical setup is like this:

I got 2 quad NICs in each server, and a dual NIC on the motherboard for the management.

I want to run it with 3(4) different subnets:

10.100.100.X (vCenter server)

192.168.99.X (ESXi Hosts)

192.168.253.X (VSA FrontEnd)

192.168.254.X (VSA BackEnd)

I get this warning when selecting the hosts:

- So I created the vSwitches manually.

However, when trying to start the actual install of VSA, I get this error:

- Searching for this error on the net gave me basically nothing..

So, here I am, lost in where to move from this point.

I have also tried configuring VSA with the same subnet as the ESXi hosts, but then I get an error that the vCenter cannot contact the cluster management IP, which makes sense since it is on a NIC that only has connectivity to the other host.

My current vswitch config looks like this:

Any help is much appreciated.
