Using Passive FTP in vThunder

I, unfortunately, have an application that sits behind vThunder that uses passive FTP and am having trouble getting this to work.

I can configure a single port and limit the application to a single port using passive ftp and the service works but I need to use all available ports in the passive FTP standards (49152-65534) and I cannot find how to configure a large port range to make the application work.

Can anyone provide me with configurations to make this work or point me to material that will help?

For the high port, you could rely on a wildcard “port 0 tcp” vport to accept the high port connections. If you need both connections sent to the same backend server, you’ll need to use a source IP persistence template with “match type server”.
