How to pass low voltage ethernet cables through drywall with insulation (lemm.ee)

Hello everyone, I am pulling my home's existing ethernet cables from the garage and into my home to install a network rack. Currently my garage does not have insulation (for a future project), so it get's too hot during summer for my router to live there, so I want to install it in my mudroom where there is insulation. My question is if I drill a hole to put some sort of cable cover (ie. https://a.co/d/1hHosME) will it affect my home's insulation too much where I should be doing something else? If so, what should I do to improve the cable runs?

So I did a detailed write up on this comment about how to run cable.

Doing it in a wall with insulation requires a little more work when fishing with a fish tape, but is totally something a normal person can do.

Hey, what do I need to do to meet code if I run ethernet like this? Fire blocking where it goes through the plates? If I do a tube, is there a code limit to number of cables running in it since they're PoE?

They make fire block spray foam that you can spray where tubing penetrates between floors and exterior walls. Most internal walls don't require any additional fire protection.

For low voltage even poe they're is no limit I know of other than the physical number of cables that will fit.
