Typically end user traffic is directed to the virtual server, which then load balances the connection across the two backend servers. The return traffic from your servers will either route back out through the BIG-IP (specifying it as a default gateway for example) or the BIG-IP will use source NAT (SNAT) to ensure that all return traffic from the servers comes back through the BIG-IP.

 

Hope this answers your question. If not, keep 'em coming.

I think i'm still not explaining it right. What you said make perfect sense but this is what I need. No one will use the browser (that I know of; this may be where i'm confused). Basically I have two servers that do the same thing. Want to set up F5 so if one goes down it switches to the other one. How does the virtual server IP play a part in this kind of setup?
