To know exactly what ports you will need to open, you will need to either: a) talk to the vendor to get specifics about how their system has been configured. b) Use a protocol analyzer, such as tcpdump or wireshark, to look at the traffic, both from outside your firewall and inside your firewall.
5 Μαρ 2024 · FTPS typically uses port 990 for control connections and port 989 for data connections under implicit security. However, FTPS can also use port 21 when operating under explicit security. Learn more about the difference between FTPS vs HTTPS for secure file transfers.
22 Σεπ 2021 · This is typically achieved by initiating communication on a control channel (commonly 21), and then setting up data channels over either set or random ports - usually port 20 when determined, or between 10000-20000 when random.
