I know how to add the extra IPs for the additional VLANs on the single NIC, but I'm not sure how to go about directing the traffic to the separate VLANs.
On the Windows level is there anything I need to do besides enable tagging on the NIC?
On the switch side I'm guessing I just need to add multiple VLANs to the port the NIC is connected to and the tagging will determine which VLAN the traffic goes to.
Is there anything else I need to setup?
That sounds like just about everything you need to do. On the windows side of things, go to the properties of your nic and hit the configure button next to your nic's name. there should be a tab (assuming intel or broadcom) that says VLAN. Add the vlans you want, and individual nics will appear in the network connections. On the switch side (assuming cisco), in the interface configuration mode, use:
would obviously be if you wanted 4 separate interfaces, one for each of the vlans listed above.
