Networking Setup

I am currently setting up an ESXi host with one NIC and I need to have access to 3 different subnets through this one NIC.  I have the managment network and two VM networks.  I currently have my connected switch in switchport trunking to the host.  The managment network has connectivity as my computer on a seperate subnet is able to use vSphere.  My other 2 networks have no connectivity (VM Network & DMZ). This diagram should help with any missing description:

I appricate any help with this problem.

Hi - welcome to the community.

Trunking the ports is all good and well, but you need to somehow route between these networks.

Either you'll need a physical router (or 'router on a stick on this case') - or you could consider using a VM appliance to act as your router.

I generally use a Vyatta Appliance - I have a quick walkthrough for setting this up here:

but there are many good resources on the web (and alternative appliances)

One day I will virtualise myself . . .

I apologize I missed that part of my puzzle.  On another end of the switch, there is a port trunking to a router.  This is forming the router on a stick.  Is there anything else I should investigate?

Welcome to the Community -  I would double check the ocnfiguration of the trunk ports on the physical switch to make sure the vlans are identified correctly

Double checked and here is what I have showing:

The top two are my switch of course and the bottom one is the router on the stick.  I appriciate the help, but not quite there yet.

I found the solution.  It seems that the VM converter tool did not convert my linux VM's NICs correctly.  With some work I got them back online and the network is working smoothly.  Thanks for your help all!
