Monitor Log Access of IMAPS and POP3S on F5

Hi all,

I used to monitor Log authenticated from Users of POP3S and IMAPS (993 and 995) on CAS Server.

But now when I use LTM to Load Balancing Traffic POP3s and IMAPS, so on CAS Server i only know the F5 IP as a source IP, i do not know the Client IP.

So can any help me to find a way to monitor User, Client IP and Authentication status of POP3s and IMAPS on F5

Many thanks,
