FTPS_SSL_ Termination

Hey @bob_ziuchkovsk1
thanks for your FTPS iRule

There are still a few small things that need to be adjusted to make it work.

1. The same variable again "static::pasv_max_port" is incorrect it is already in use.
2. To use this iRule on multiple virtual servers it needs a little more dynamic.

 # -- REMOVE OLD --

 # Vserver IP to advertise for incoming PASV data channel connections
 # NOTE: the commas are NOT a typo.  This is the format used by FTP protocol
 set static::pasv_max_port "10,0,0,46"


 # -- ADD (under "when CLIENTSSL_DATA" ) --

 # uses the known virtual server ip address (client context)
 set static::vserverip [IP::local_addr]
 set static::vserverip_comma [string map {. ,} $static::vserverip]



 # -- CHANGE ( under "when SERVER_DATA" ) --

 # respoding the virtual server ip address
 set pasv_response "227 Entering Passive Mode ($static::vserverip_comma,$our_pasv_str)\r\n"

Tested this on Version: 16.1
