1) If you disconnect the Ubuntu server from the network altogether, do you still get a response? 2) The LinkSys router suggests that your question is off-topic for Server Fault and probably belongs on Super User.

comment What is the request flow in BIG-IP load balancers for NONE preference?
The Virtual IP that the client connects to is hosted on the active unit. The active unit informs its router of that fact via ARP. So, you could say that the client's request makes some number of hops through the Internet, and the last router forwards the packet to the active unit because that's what its ARP table says.

@JavaTechnical Perhaps you should ask a new question.

comment What are the differences between Floating IPs and Virtual IPs?
@JavaTechnical The cluster members negotiate amongst themselves which one is active. For BIG-IP load balancers, the election is influenced by the Redundancy State Preference setting.

comment What are the differences between Floating IPs and Virtual IPs?
@JavaTechnical IP-to-Ethernet mapping is done through ARP. The members of the cluster coordinate amongst themselves such that at any time, only the active unit will respond to ARP requests for the floating IP. During failover, the new active unit sends a gratuitous ARP announcement informing all other devices on the subnet (especially the router) that the new active unit's MAC address should be associated with the floating IP.
