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.
The first sentence is not really true though.
If you really want to get anal about it, yes I know there things like CNAME, PTR and MX records too but that’s outside of the scope of this discussion.
DNS doesn’t deal with ports, there’s no way to say:
homelab.example.com
should point to IP address1.2.3.4
and port12400
.DNS can deal with ports.
You can use a SRV record to specify the port for applications (not browsers) that support it.
