SSH proxy implementation

Hi , my scenario is -

 users need to connect to sftp server - via F5 - 

F5 has snat so sftp server cannot see real ip of users .

i need to implement an allow list of username + client ip on F5 .

on F5 i can see client IP - and if i implement ssh proxy - can i get username as well?

thanks

      Thnaks for the response 
      Question - once i setup ssh proxy and it has the option to allow commands for users 
      would i be able to log users - and then i can do a compare from datagroup and allow ip / user connections

        i have ssh proxy configured now - and ssh proxy is logging client ip and username 
        "ssh_serverside_auth_success","10.10.10.10","puser"
        now the task how can i extract this information and compare it against a data group 

        with SSL - there are irule options to extract info with CLIENTSSL_DATA
        how can i extract the username from ssh proxy ?

        thanks
