Thanks for everyone's help, it has been insightful. I did make the following changes to:
rdr on $int_if inet proto tcp from any to any port www -> \ 127.0.0.1 port 3128 pass in log quick on $int_if inet proto tcp from any to \ any port 3128 flags S/SA keep state Just now it looks like the rdr line is not redirecting anything to squid on port 3128. Could line be more for a NAT environment? Any suggestions?
