How to configure FTPS (FTP over SSL) vip ?

Hi Team ,

How do we configure FTPS (FTP over SSL) vip . Is it same as other vip ports or required any additional settings enabled ?

Is the below config correct :

ltm virtual TEST_SFTP-990

{

destination 10.20.30.40:990
mask 255.255.255.255
persist {
    source_addr {
        default yes
    }
}
pool TEST_SFTP-904
profiles {
    fastL4_3600 { }
}
source 0.0.0.0/0
source-address-translation {
    type automap
}
translate-address enabled
translate-port enabled
