SNAT - same VLAN ?

Do we need SNATs if the server is in the same VLAN as the self / floating IPs ? the default gateway of the server is not the F5 in this case...

 

for ex

 

external VIP - 172.18.2.153

 

pool members - 172.18.33.150 & 151… self IP of f5 - 172.18.33.130/131

 

In this case snat is disabled.. and the server has a default gateway to the switch, and not the F5.
