I have successfully installed Bitvise SSH server on our Windows Server. I can access it when I am on our network using an FTP client like WinSCP or Filezilla. However, when I am using a machine outside the network, the client can not access my host (ftp.domain.org).I have looked at https://www.bitvise.com/getting-started-open-to-internet and https://www.bitvise.com/ssh-server-guide-opening and I should be fine (ports opened). Is there anything else I should check?
Could it be related to the router instead of the freshly installed bitvise server? I want to make sure that I have explore all possibilitie before checking with the network admin.
