Server Load Balance based on client address

Hello there.

I'm a long time Fortigate user but first time posting here . Lets see if any of you guys can help me with this.

I'm about to set up several web servers and use a fortigate cluster as load balancer using the virtual server feature. That seems simple so far. I've made some proof of concept and it works pretty well (and fast). However, I'd like to route requests based on the client address too.

At first it seemed that the solution would be to create two virtual servers and the policies could match the the source ip, but alas you can't create two virtual servers listening on the same IP and port (it makes sense anyway).

Do you know if that's possible at all or will I have to use something more flexible like HA Proxy.

Regards.
