The simplest configuration would look something like this:

 

  • Define a system default route (0.0.0.0/0, gateway IP)
  • Wildcard forwarding VIP
    • Protocol: whatever you need here
    • Source: 0.0.0.0/0
    • Destination: 0.0.0.0/0
    • Port: 0
    • VLAN and tunnel traffic: client-facing VLAN
    • Source address translation: disabled
    • Address/port translation: disabled

This VIP has the effect of listening to all traffic, maintaining true source and destination in the packet, and forwarding to the system route. Traffic routes to the BIG-IP via the client-facing VLAN self-IP.
