Tailscalar here: there is a bandwidth limit, it's a funnel, not a hose. We don't announce what the bandwidth limit is, but please keep in mind that it does exist. I would suggest setting up your media server inside your tailnet for the best experiences, but it depends on who you are sharing it with and why.

I might be missing something; isn’t a Tailnet a bunch of user devices with wireguard tunnels connecting to each other directly? Where does the limit happen?

(And thanks for your work!)

Edit after 1 minute: of course, limit on Tailscale Funnel itself. (Too deep into thinking about Tailscale and forgot about the actual topic of the post. )

Tailscale internally tries to punch NATs to make connections, but if it fails, it will use relay servers. These connections are throttled, and there'd probably be usage limits at some point.

If you allow tailscale through by using ipv6 or port forwards, tunnels will run at line speed with no limits.

fundamentally, something has to be punching NAT somehow, so they're probably taking the traffic on their own servers and relaying it to your machine via the tailnet.

Hola, how would the bandwidth limit work within the tailnet if I am accessing it from outside my home network? Wouldn't it incur some bandwidth on Tailscale's end?

I wonder if the DERPy-stuff helps remove most of the bandwidth concerns - thinking out loud...

Only the setting up of the session, it's effectively P2P then. Routing traffic back out onto the general internet for people without tailscale in your private net will be b/w limited, as mentioned.
