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

What is your current network setup? Where are these Vlans setup on?

This seems like an odd setup that you need to change IP's to access the different Vlans, if you have something that is capable of setting up Vlans, then it would be capable setting things up to allow access across Vlans?

If you don't want everything on the main network to access all areas, you could create a 5th Vlan that only certain devices like the device you use to check on everything sits on that has access across all areas of the network. I do this at home as the Wife and Kids devices sit on a separate network to my devices which can go anywhere they like.

My main network is on a N4064 - 192.168 two separate vlans on a N3048P - 10.10 the other is on a dumb switch - 10.2 vlans are setup within pfsense.

I know how to assign ports within both Dell switches but then I have to physically move my patch cable and frankly I'm lazy

It was setup for me and I was only shown how to hop back and forth. I'm not a networking guy at all so I'm trying to learn, and I assumed there was a better way.

Would like the NVR to have access to both the camera vlan and the main network and give my main computer access to the equipment vlan I have a system on that vlan that runs my CNC routers/3d printers that I'd like to keep from the Internet be great to just have the access on my main pc usually access it through the kvm
