Hi everybody,

We have a difficult to access the Ftp server on the DMZ with SSL connexion.
Without SSL no problem, the user can connect and puting file on the server.
But if the external user,with public IP addresse, use Ftp over SSL or
Ftp over TSL session, "500 'AUTH SSL' : Unknown Command" appear on the
client ftp console.
If we use Internal IP, with Ftp over SSL, the connexion work fine.

Public IP on Internet and Private IP on DMZ are static and dynamic nat

Have you idea for help me ???
