hmm, a little bit confusing this setup, but some clarifying is needed.

 

 

Host A,B and C is on same subnet but is they on the same Vlan id? pretty important if we talk L2 and if the F5 is the router or you use VRF:s etc.

 

Or you maybe using routing domains or maybe "group vlan in the F5 to fix the above"?

 

 

 

However, if the F5 isn¨t the router for this vlan (or vlans) then you don´t need to use any snat or forward vip:s and so on. You only need SNAT when host C want to use the VIP for host A and B because of asymmetric routing.

 

 

 

But give some information about your setup.
