I use CompleteFTP as our FTPS site,
but I found some FTPS Client (ex:CuteFTP)can't connect correctly under some NAT enviroment.
Because these FTPS client does not support AutoPassiveIPSubstitution,
althought CompleteFTP support External IP address setting,
when client use NAT, client may not recognise the External IP address ,
so data connection will fail.
When FTPS client use EPSV mode,
and FTPS server support EPSV(ex Microsoft IIS),
this problem will resolve.
Can CompleteFTP support EPSV in future release??
