Right now I currently have 3 NICs dedicated to three separate subnets. Could I just LAG the three NICs together and then just setup three VLANs for the separate subnets and make the three VLANs accessible across the LAG? Does that make sense?
If that indeed makes sense then do I really need to set an IP for the LAG?
Yes, this is a common use case to allocate bandwidth across a trunk. E.g. one VLAN can use 1.5 Gbps, leaving 1.5 for the rest.

A LAG is not a layer-3 device and does not need an IP address any more than a single cable.

OK new question...
I have the LAG setup on OPNsense and its protocol is Load Balance. It is connected to a Netgear switch that has its trunk ports set for LACP. When I change the protocol on OPNsens to LACP I lose the LAG completely. It does not seem to like LACP. Has anyone had this kind of issue and is it incompatibility between OPNsense and my switch?
