when the traffic goes back to LTM interior VS and then to the IIS servers, client IPs are disappearing and I can see only the SNAT IP as requester.where did you see client ip? was it x-forwarded-for header?

Secondly, I am using cookie persistence but all the requests are going to the one pool member on LTM. it is on interior virtual server, isn't it? have you tried to access the interior virtual directly (skipping exterior and asm)?
