That's incorrect. Heres an excert from calamaris, a squid log interpreter. As you can see the log
still has the correct ip addresses, and calamaris does the hostname lookup. Below that is an excert
from the access.log from squid.

Isn't there another downside in that your Squid will only see NATted client IP addresses i.e. only
the address of the M0n0wall box itself?
This would make Squid logs meaningless. Maby not a big deal for many sites, but a pain for others
(no abuse tracking, no reliable accounting etc.) I used to have that problem when doing NAT-based
HTTP traffic redirection on Linux boxes.
