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?

MVPAK_1947 Is this public IP a NAT on a firewall that is translating the self-IP to a public IP? I'm unsure what public IP you are referring to or the tool that you are using to gather this information. If you can provide some additional information we should be able to assist you further.

NimbostratusIn fact to try to give more details and clarifications on the case, I resume.
We have an architecture with two F5 ASM appliances, to facilitate the work of our partner and collaborator, we have deployed a web application to have the public address from home.
This link is often sent to partners to retrieve this information. It is to authorize them to give them access to certain application that we put at their disposal.
This is where we find ourselves in this case, without really knowing what is wrong. Knowing as said, that we have the same configuration with the second F5 ASM of the other site. If we switch the flow on the latter everything works. Example my public ip will show normally.
We use automap on both on LTM VS configuration.
