If the vmware instance is running bridged it quite likely won't notice
if the MTU setting it's trying to use is incompatible with the
networking provided by the hardware host, and will happily send
oversized packets only to see those silently dropped in transit.

But that's a question better directed to a vmware forum. Squid
operations require a properly functional network setup, which includes
properly configured MTU settings.

Detecting MTU failures is a little tricky by causal testing as you only
notice these problems when some application tries to send a large chunk
of data at once. Easily tested using ping with varying packet sizes
however and observing the result using tcpdump/ethereal.
