I don't know how to disable ARP properly in Linux...

 

Using arp announce/arp ignore to disable ARP

 

http://kb.linuxvirtualserver.org/wiki/Using_arp_announce/arp_ignore_to_disable_ARP

 

f5 is adding client IP to the packet and because of it, the server will send the response directly to client, right?

 

source (client) ip is not change because f5 does not do snat. so, server can send response to client directly.

 

If loopback is not configured, the response goes through LB, right?

 

there are 2 options to force response through f5. one is to change server default gateway to f5 and the other one is to do snat on f5. when doing snat, source (client) ip will be changed to f5 ip. so, response packet will be sent to f5.
