Hi AK_1947 ,
It’s a strange thing , because you can’t see the Self/floating ip addresses instead of the public or original source ip of the client.
The only way to see that if you have TWO f5 in one path or behind each other Like the below snap-shot :I think there is a misconfiguration in network design , because the above snap shot is the only possibility to see the self/floating sends traffic if you use the ( SNAT ->> auto map ) option in the first F5-ASM1 Appliance.
So check it again , no further configuration to do from F5 side , the only thing is to check and review your network design configuration and traffic flow paths.Hi AK_1947 - did Mohamed_Ahmed_Kansoh or Paulius's replies help you out, or are you still struggling?

NimbostratusHello
Sorry for the delay I was out off.
Find my answers below on yours questions :
Is IP : 10.135.0.53 the self ip address that you mean it appears to you instead public ip address ?
Yes, that's not good for us.
Also , Do you mean that Public IP of user should be appear instead of self ip address ?
Yes, it should be
Also , Do you monitor this behavior by ASM Event logs or explain how does the tool (url) work ?
Yes, it's . Like I said earlier, we got another F5 ASM and when the traffic is on that one, all works.
Both ASM configuration are the same, I got suspicion on ASM network configuration (Interfaces, self IP address and VLAN ) on the one we got the issue.
Best regards
