It looks like they did add support but you need to force it to connect over IPv6, via the --edge-ip-version argument
--edge-ip-version value Cloudflare Edge ip address version to connect with. {4, 6, auto} (default: "4") [$TUNNEL_EDGE_IP_VERSION]

not going to work on service install, probably just going to have to modify the service's unit file i.e sudo nano /etc/systemd/system/cloudflared.service Stick --edge-ip-version 6 on the execStart line, after /usr/bin/cloudflared, before tunnel Your ExecStart should look something like this ExecStart=/usr/bin/cloudflared --edge-ip-version 6 --no-autoupdate tunnel run --token <token> sudo systemctl daemon-reload sudo systemctl restart cloudflared If it worked, check sudo systemctl status cloudflared Should see something like, with the IP being an IPv6 Dec 20 09:26:18 server.hostname cloudflared[482675]: 2022-12-20T17:26:18Z INF Connection UUID registered with protocol: http2 connIndex=1 ip=2606:4700:a0::5 location=EWR (This assumes using systemd, like on Ubuntu/Debian, etc etc)

Working beast Thx you dude Another quick question, is it possible to close in IN and OUT all the ports?

Can you elaborate? If you are asking if you need to open ports / add ingress rules / port forwarding for Cloudflared/tunnels to work, then nah you don't need those, it's an outbound connection from your server to CF's Edge.

Ok, all input ports can be closed. The output must remain open as usual ?

If you're talking about egress rules / egress ports, the list of what ports/domains they use is here: https://developers.cloudflare.com/cloudflare-one/connections/connect-apps/do-more-with-tunnels/ports-and-ips/
