Transparent load balancing without F5 as a gateway

Greetings,

 

This sounds like a forwarding virtual server. The section "Emulating stateless IP routing with BIG-IP LTM forwarding virtual servers" discusses this in more detail:

Hope this is helpful!

In fact, behind the F5, I have a pool of servers (2 for instance) that I want to load balance. These servers provide the service but need to obtain the client IP to do filtering. With that, if the F5 is not the gateway of these servers, the responses go directly to the client which doesn't know the IP source (the server IP) so the returns packets are never taken into account.

 

I don't know if it is possible but the aim is to do that. I will test with the forwarding virtual server and the iRule. I will tell you if it works.

 

Thank!
