Well, I'm sure not that ggod in squid configuration, but thinking about
a layer 7 switching solution using virtual IP, to let squid answer to
clients request directly I should use a TCP handoff. In such a case,
squid needs to use the virtual IP address to answer to clients (binding
squid instance to the virtual IP in squid.conf) while, to speak with its
cache_peer it needs to use its real IP address (using something like
udp_incoming_address and udp_outgoing_address in squid.conf). While, not
using wirtual IP solution but natting only, I don't need neither to bind
squid to wirtual IP nor to change udp_incoming and outgoing_address.

Am I wrong?!?
