I am currently looking to migrate my VMs from a free ESXi install I’ve been using in my home lab to Virtualization Station. Right now the ESXi host has 2 physical NICs, and the managed switch has the ports for those NICs set to untagged VLAN 1, and tagged VLAN 3 and 4. The NICs themselves have no IPs associated directly with them, but all VMs are attached to VLANs 0 (external tagging), 3 or 4 (0 and 3 in the case of one VM). VLANs are isolated by the router.
Here’s an image of the topology:
My QNAP NAS is an h874u, and currently acts as the iSCSI storage for the ESXi VMs. The 2 NAS NICs are static IPs with the managed switch ports set to untagged VLAN 3. If I’m reading the QNAP documentation correctly, it looks like I’ll need to add those NICs (one at a time) to VLAN 3 through the NAS software, and then change the managed switch ports to untagged VLAN 1, tagged VLAN 3 and 4. Now, this should allow the cards to keep their IP and VLAN membership, and then I can add VMs with their virtual NICs to VLANs 0, 3, and 4 as I do today. Am I understanding this correctly? Also can a virtual switch handle traffic among multiple VLANs? That wasn’t immediately clear from the documentation.
