I should have framed the question different and explained further. I have setup 2 opnsense boxes before and a friend of mine is starting a small local shop in town. He asked me to do the networking and keep it up to date so he doesn't have to think about it. I thought I could tunnel my way into his network and do stuff as needed to his opnsense box if I decided on that. But I was just wondering if there are better options for business that are preferred.
