        So with no IP squid is binding to all interfaces and with an IP it is 
binding to a specific interface / IP.

How are you sending the packets from LVS to the squid server ? Are you 
using the TUN method for example. Which would have the packets "arrive" 
on a different interface then eth0 for example.

So maybe squid is listening on the wrong interface ?

Hard to tell with out more info.
