I "think" I understand that all firewalls are software. However, I am splitting the monthly internet bill with a roommate who has the ISP modem/router in his room. I would like add (if possible) more security measures. (I cannot get my own ISP in my room; as the house is designated as a “heritage house” and the landlord won’t agree to any “drilling”). I have my macOS firewall turned on to “block all incoming connections”. I also use Tunnel Bear VPN.

Are there any recommendations (hardware or software) available considering my situation?

  • I fail to see how a hardware solution has anything to do with macOS. – JMY1000 Dec 20 '17 at 5:31
  • @JMY1000 - technically speaking, the Airport Express or the Airport Extreme would classify as a "hardware solution" in this scenario. – Allan Dec 20 '17 at 8:51
  • I'm voting to close this question as off-topic because this does not seem Apple specific it would be the same for a windows pc. – Mark Dec 20 '17 at 11:55
  • @Mark - there are many things in the Apple-verse that would also apply to a Windows PC; that in and of itself doesn't make it off topic. – Allan Dec 20 '17 at 13:48

If you want more security than what you have now, you could add a hardware based router/firewal between your roommates Internet connected network and your "network"

What you would be doing is connecting your WAN port of your router to your roommates LAN. This will create a "double NAT" network, where your roommate becomes your ISP.

The benefit this has over a highly configured firewall is that the router will immediately block all incoming traffic (by default) on the roommates LAN but allow you egress to the Internet.
