I just wanted to see what other selfhosters backup emergency plan is if the primary internet router goes offline but the internet isn’t out (ie a router reboot would fix the problem), leaving you without access to your stuff even via vpn.
the options I’ve considered so far:
- cellular smart plug to reboot router
I tried a ubibot smart plug (SP1) that is supposed to work with cellular, but the device or sim is bad. I’m currently troubleshooting. The problem with this one is it requires a proprietary cloud service, it’s supposedly self hostable, but it’s a pia to setup and their app port can’t be changed easily allowing for a reverse proxy setup on VPS.
- the other option I am considering is cellular wifi router and a wifi smart plug connected to that device to reboot router
what other options have I overlooked? Also, specific models of devices would be helpful info from others doing this already.
TIA!
Edit: also just thought of possibly a cellular internet backup on my opnsense box, but from everything I’ve read that’s also very involved to setup
Redundancy. I have two independent firewalls, each separately routing traffic out through two totally independent multi-homed network connections (one cable, one DSL, please god somebody give me fiber someday) that both firewalls have access to. For awhile was thinking of replacing the DSL with starlink until Elon turned out to be such a pile of nazi garbage, so for now DSL remains the backup link.
To make things as transparent as possible, the firewalls manage their IPs with CARP. Obviously there’s no way to have a single public IP that ports itself magically from one ISP to another, but on the LAN side it works great and on the WAN side it at least smooths out a lot of possible failure scenarios. Some useful discussions of this setup are here.
