Hello, can you get access to your address but only to the right port? 7171?
if using DNS only (grey cloud ) , no. If you’re using Cloudflare Proxy , it will only proxy HTTP requests to these ports:
if you want to lock down traffic to one port and/or proxy non-HTTP traffic, you’ll need to be an Enterprise customer and leverage Cloudflare Spectrum to proxy the 7171 port.
Otherwise, you can use IPTables or the more user-friendly UFW Linux application to block ports you don’t want to allow access to. Cloudflare with will still only proxy the ports in the above article.
