I'm setting up a jellyfin server, and want to access it on the internet. I created a xxxxxxx.duckdns.org address for it. I have installed caddy with duckdns addon (first installed regular caddy, then overwrote /usr/bin/caddy with this custom caddy). My caddy file is as follows
XXXXXX.duckdns.org:9091 {
reverse_proxy 127.0.0.1:8096
tls {
dns duckdns XXXXXXXXXXXXXXXXX
}
}
Started caddy and here's my status. Doesn't show any errors:

However, my reverse proxy doesn't work. I can't ping it. Same thing happens when I ping my global ip
PING xxxxxx.duckdns.org (104.183.123.226) 56(84) bytes of data.

I have previously setup dynamic dns successfully on raspberry pi for jellyfin, but unfortunately I didn't document the steps.
I'm on ATT Fiber with BGW320-505, and have a Deco X5700. Please advise.
Yeah I've port forwarded 9091, 443, 80, and 8096 for good measure.
Do you have CGNAT?
If you run
traceroute 1.1.1.1the first hop should be your router, and if the second starts with 100, 10, 172, or 192, then you probably have CGNAT.The second one is the ip I use to login to my modem settings. (192.168.1.254)
What's the first IP and third?
Oh so you've got double NAT. You'll either have to put the modem into bridge mode, or port forward on both the router and modem.
That worked, thank you! I added all the ports at the modem level and after restart it's working now, thank you so much!
No worries! I'd probably prefer bridge mode instead of double NAT, but I guess whatever works for you.
