There are many ways to update dns automatically, I have used this container in the past. You could probably even write a bash script/cron job that checks your IP and updates it with curl depending on your DNS provider.
If you are already running tailscale you may be interested in using a funnel, which lets you accept and route internet traffic to your tailnet. I don't use tailscale so can't comment on how good/bad/useful this is.
You could also run some sort of service like frp from some remote box (like a VPS in DO/Linode/etc). This or the funnel lets you not expose/advertise your home IP address if that is a consideration.
Oooh thanks for the tip about
frp. Interesting.I actually just migrated things to a setup that is pretty neat using FRP: I run frps on 2 Linodes in the same datacenter and have set up IP sharing for failover between them (which is a neat feature Linode, Vultr and probably a few others offer), and then I run 4 frpc's, two for each frps in case one of them breaks somehow. Lots of redundancy without all that much effort.
It sounds pretty awesome. Just wondering if adding additional complexity to the setup is worth it to obfuscate my home IP. Easily setting up redundancy is a good feature in that regard though.
I usually use autossh to establish a persistent port tunneling but sometimes got frustrated with the performance of the encrypted tunnel for some use case. Sometimes I don't need encryption, but need to saturate my nic. frp seems to fit this use case.
