I’ve got an EdgeRouter LITE (ERL) which I used as my home router until a powercut fried it a while ago (looks like I’m not the only one to have this issue). The symptoms were it powering on but not giving any DHCP addresses, or after a factory reset responding on the default IP of 192.168.1.1. It was a real shame, because it had been a great bit of kit up until then. I am a complete hack when it comes to networking, and it struck the balance right between letting me do what I needed to do, without overwhelming me with complexity. I’d replaced it with a SonicWall TZ105 but having utterly failed to get the latter to permit OpenVPN traffic (so I can access my home server when on the road), which I had done with no problem on the ERL I thought I’d try and resurrect the ERL using the instructions here.
