Hi,
I wanted to forward the port to my Traefik install on my TrueNAS server. Unfortunately I have now learned that my ISP restricts the range of ports that I can open externally to 12396-12415, so internally I can open port 443 to port 12400 externally. So far so good, but how do I point my Cloudflare DNS record to this port?
My router is a Fritzbox 7530 if that’s relevant.
Currently I am using Cloudflare Tunnel to access my server remotely. But with this I’m always accessing my server through the tunnel even when I’m at home.
If that is a concern (I don’t see much of an issue, but everyone’s got different requirements, so no judgment here at all), then you’d probably want to setup a recursive DNS server inside your network, configure that DNS server to resolve those internal services to your intranet IP address, when it cannot resolve, it recurses to a public one (ie ISP, CloudFlare, quad 9, Google etc). Then, change your network’s DNS to that internal one, so when you’re on your network, you get internal IP address while off network you get CloudFlare tunnel routing.
I think I got it working now. The last time I tried I couldn’t get it to work.
I don’t have your specific port issue, but it sounds like the setup I have would get around your ISP port restrictions as use CloudFlare tunnels externally, LAN internally, and no ports open.
