Long story short, I’ve got an Ethernet cable on the outside of my garage that I want to route inside.

The cable is pretty short tho, so I can’t just drill a hole and stick the end of the cable inside my garage to route from there. I have to make a connection outside of my garage.

I was thinking of adding the Ethernet connection to it as it is, doing a female to female coupler and a new, longer Ethernet cable from there and into the garage, but that’s obviously not secure and someone can just unplug and hook up to it.

Is there a way to secure or lock that female to female coupler? Or is there another way to do this? I can’t add another box there since it’s a townhome and HOA would probably be up my ass.
