What is Squid saying on startup about the stack type detected?
 (may have to set debug_options 3,2)

Linux has a hybrid TCP stack. Which means IPv6 ports can receive IPv4
traffic unless you change something. Have you got any custom config in
your TCP/IP settings that might have changed the stacks v4-mapping
behaviour?
