I once bought a router to use for my internet when I moved into my new house just to find out that it “wasn’t compatible” with Verizon’s service. I still have it (because I’m terrible about returning things). Is there any point in keeping it? Is there anything fun or interesting that I could do with it?
I run double firewalls.
I just don’t fully trust the ISP router, so I disabled the wifi and hooked it up to my own router. If the ISP router gets hacked, my internal network doesn’t get exposed.
Port forwarding is a bit harder, but you probably aren’t even doing that at all (and it still works anyway, it’s just an extra step).
