4port Nic instead of changing IPs? (alien.top)

I'm not much of a networking person. But I understand the importance of different vlans. Currently I have 4 separate vlans that I change my PCs ip address to access If I buy a four-port nic and assign each port to a separate lan does the computer know which port to use to access the appropriate traffic or is there something else I should be doing instead?

Only the main network has access to the outside internet and it would be nice to have one system that could access everything. Or even allow my email server access to different vlans to send out alerts.

Main network
NVR & Cameras
KVM & IPMI
Various equipment

My main system is normally powered off so I wouldn't see this as an added security risk But it would definitely save some time when I sit down to check things out

User your router to route between vlans. It will require you set up proper firewall rules. Then you can access it from any system you like.

Alternatively just pass the tagged traffic to your desktop and set them up to each have their own IP address on your main NIC. There really is no reason to have a NIC for each VLAN.
