Unable to set reverse proxy - IP doesn't seem routable

[yepitsmealright]

Hello,

I have been following the Quick Start guide (https://jellyfin.org/docs/general/quick-start/windows/), but I have been unable to setup a reverse proxy using Caddy.
Worth noting: I have essentially no networking knowledge or experience.
Not sure which info is needed, so; I am running Windows 11, latest Jellyfin & Caddy versions, my router is a tp-link EC220-G5 v2.

https://jellyfin.org/docs/general/quick-...r-settings
I couldn't find anything referring to a WAN address in my router's page. All I did find, on the index is "IP Address" (from what I could tell it is the same thing), which did not match the IP from step 5. On no other pages within the router did I find an IP which matched this one from step 5 either. The rest I think I did successfully (i.e. port forwarding and Caddy installation).

I continued until https://jellyfin.org/docs/general/quick-...s-routable, where I could not access the page using my phone's mobile data. I could if using WiFi or my PC, but I'm assuming that's meaningless.
I didn't proceed past this point.

One point of confusion I do have, is in step 3 of the above, the guide says to use the IP from https://ipv4.icanhazip.com/, but I thought you should be using the static IP assigned earlier in the guide? Am I misunderstanding? Don't think it would make a difference in my case, but wanted to ask regardless.

I am going to bed now, this has given me a headache, lol. Any other required details I will provide tomorrow.

There are two IPs you need to track for this process. Your PUBLIC IP address, which the "icanhazip" site shows you, and your servers PRIVATE IP address. The private address is usually something like 192.168.#.# or 10.#.#.#.

Setting a static PRIVATE address ensures that the rule you create in step 10, creating a port forwarding rule, will always go to the correct host. So you'd use the private IP you statically assigned in step 8 for setting up the port forwarding rule in step 10.

The IP address you got from "icanhazip" will be used when you setup your DDNS farther down the walkthrough.
