ESX 4 and Vlan / 8021.q How to create a Vlan per machine to a netgear GS724Tv3

Hi Guys
I have a simple question that I cannot get my head around, - Picture this
A ESX server with 3 VM's on it All going through the same nic to a netgear GS724T.
On the switch I have a Firewall that can talk to each of the VMs (All different subnets)
On the switch another server that I want to talk to only one server.

My understanding is to create a port trunk on the ESX server and then enable taging on the switch etc .
How ? Thoughts ??

TIA
LVL 1

For this issue put  NIC's physical interfaces on a trunkport using 802.1q.

After this create the VLANs you require on the networkswitch. Create a vSwitch on the ESX host and configure a portgroup for each VLAN.

If you require routing between subnets you will be needing an additional router to do this for you.

Either put the other server on the same VLAN as the VM you want it to talk to or use interVLAN routing to accomplish this.

Quite straight forward, create a Trunk Port from the Netgear GS724T to the ESX server, make sure that you also have Tags for 3 VLANs, eg 101, 102, 103 on the physical switch, and Tag the ports that connect the trunk to the ESX server.

Create a virtual switch vSwitch, with 3 portgroups, with VLAN Tags of 101, 102 and 103. Label the port groups 101, 102 and 103.

Assign NICs to each VM with porgroup of 101, repeat for VM2 (portgroup 102) and VM3 (portgroup 103).

Hi Guys
Any chance of a step by step please ? This is doing my head in.....
I have created a Vlan (ID2) containing ports 1 and 2 and 3 (Untagged) Vlan 1 (Default contains all ports Untagged). -
port 3 is ESX
Port 2 is this other server
and port 1 is the FW
Hopefully that  will be that on the vlans ? how do I do the ESX part ??

I got it

The port that needs to be part of several Vlans (ESX server) is setup as a trunk (Tagged) the port for the server that needs isolation is untagged,
Then created a new port group on the ESX Vswitch with the right vlan - and wholla !

Funny though that NEtgear support could not even help !
Thanks Lads !
