Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

I think there's a lot of risk exposing your home IP with services behind it. Last time I did it, within minutes the router got slammed with requests trying to break into services. It actually impacted router performance.
Great writeup!
That looks like a DDoS, for instance that doesn't ever happen on my ISP as they have some kind of DDoS protection running akin to what we would see on a decent cloud provider. Not sure of what tech they're using, but there's for certainly some kind of rate limiting there.
In my case I can simply have a bridged setup where my Internet router get's one public IP and the exposed services get another / different public IP. If there's ever a DDoS, the server might be hammered with request and go down but unless they exhaust my full bandwidth my home network won't be affected.
Another advantage of having a bridged setup with multiple IPs is that when there's a DDoS/bruteforce then your router won't have to process all the requests coming in, they'll get dispatched directly to your server without wasting your router's CPU.
As we can see this thing about exposing IPs depends on very specific implementation detail of your ISP or your setup so... it may or may not be dangerous.
