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.
DNS can deal with ports.
You can use a SRV record to specify the port for applications (not browsers) that support it.
For the discussions regarding OPs web server they want externally accessible, no DNS does not do ports.
For other applications there are SRV records, but that’s beyond the scope of the original question. It sounds like u/spacecadet didn’t want to confuse OP, and while SRV can assist certain applications with ports, pointing it out here isnt helpful.
Sure, it’s not helpful, but just because something is out of scope for the original question doesn’t mean you can reiterate objectively false statements.
They probably should have worded it like you did in your first sentence.
