# Deny CONNECT to other than secure SSL ports
#http_access deny CONNECT !SSL_ports
# We strongly recommend the following be uncommented to protect innocent

## Uncomment and adjust the following to add a disk cache directory.
#lru : Squid's original list based LRU policy
#heap GDSF : Greedy-Dual Size Frequency
#heap LFUDA: Least Frequently Used with Dynamic Aging
#heap LRU : LRU policy implemented using a heap

# Leave coredumps in the first cache dir

# Add any of your own refresh_pattern entries above these.

4. Enable ipv4 forwarding
echo 1 >/proc/sys/net/ipv4/ip_forward
5. IPTABLES RULES TO ROUTE PORT 80 TRAFFIC TO 3128 AND SEND OUTWARD
iptables -t nat -A PREROUTING -i eth2 -p tcp --syn --dport 80 -j REDIRECT --to-port 3128
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
6. Save iptables
service iptables save
7. Client side default gateway settings
Go to LAN settings at client side and set default gateway to proxy's ip 192.168.100.1
