Hi Team,   Is there a possibility we can capture client IP address on server side for LDAP, Fast L4 VS? Those which are not utilizing HTTP profile.   When I think at LTM side we can write irule...

Yes, on the LTM you can use an iRule to log the client IP address.You could also use an iRule to log the selected server/pool member IP address for each connection.

 

On the server side for a non-HTTP-server it is not that easy if you are using a SNAT/AutoMap (in which case your LDAP/FastL4 server will always see the egress self-IP of F5 as the client address).

 

If you configure your LDAP server to have the F5 selfIP address as the default gateway you don't need to use the SNAT and your LDAP server will see the original client IP.
