Issue with Filezila server, having issues with TLS. Unsecured works.

Question

I'm having issues getting through my server on TLS through port 21. 
 
 Here is setup DNS rule DNat. I tried this server on VDI at my home router with NAt and opened up all ports and worked with the same configuration and so I know its with the NAT on this box having issues with. 
 
 For traffic Any. 
 Using Service: 
 FTP: 1:65535 -> 21 
 FTP: 1:65535 -> 50000:50100 
 Going to: Public address 
 Change the Destination to: Server local address.

If you do #1 in Rulz (last updated 2019-04-17) , do you learn anything? 
 Your explanation is a little confusing. I assume that you're not trying to reach an internal server via the public IP from an internal PC. If so, then you want Accessing Internal or DMZ Webserver from Internal Network .

Hi scott stafford 
 Can you please make sure that it only requires a connection on Port 21? As for the traffic, it will also require a connection on Port20. Please add that as a service and check if that helps. And if traffic goes over Port 990 (which is more regularly used for FTP over TLS) then you'll require to open Ports 990 and 989. Hope this helps.
