Thanks looks like I’d probably get about 100 minutes at 80 watts of draw. Better than nothing but only a drop in the bucket during storm season around me unfortunately, if storms continue to grow in intensity I can expect at least 1-2 complete overnight outages a year

I have one of those for my home server, how long can a CPAP run off one of those?

Definitely how I feel when the power goes out and I can’t use my CPAP, get absolutely shit or zero sleep, I need to get a generator at some point

You would be forwarding ingress traffic(traffic not originating from your internal network) to 443/80, this doesn’t affect egress requests(requests from users inside your network requesting external sites) so it wouldn’t break your internal DNS resolution of sites. All traffic heading to your router from outside origins would be pushed to your reverse proxy where you can then route however you please to whatever machine/port your apps live on.
