      Given a system administrator is using OVS with userspace conntrack enabled on their network,

      When an FTP client like cURL initiates a file transfer using the default settings using EPRT and EPSV commands,

      Then the OVS userspace conntrack helper should correctly handle the EPRT and EPSV commands, allowing the FTP connection and data transfer to succeed.

      Userspace conntrack doesn’t support Extended Passive Mode (EPSV) or Extended Port Mode (EPRT), both of which are defaults for cURL.

      For instance, the following tests will fail when using cURL:

      • conntrack - IPv4 FTP Passive with SNAT          FAILED
      • conntrack - IPv4 FTP Active with DNAT           FAILED

      If the -disable-eprt and -disable-epsv options are used the test will pass.
