I would like to create a VIP for a FTP Server with TLS.
Behind our BIG IP LTM (Version 15.1.51) I have installed a Server with vsftp. When I connect directly to this Server I have no problem to connect with TLS.
If I use the Public address (mean I come from outside via F5) I can connect but then I get an error about the "Data Port" If I allow all Ports on the VIP and Pool, everything is fine, but this is not an option for me 😞 Does anybody has a hint for me. I found nothing here in this forum about FTP with TLS.
