Wow, thank you both for all the help. Sometimes it is the simplest of things. I am embarrassed to say that the problem was the squid wiki uses port 3129 and the default squid port is 3128 :(. Also I found that my Ubuntu server for what ever reason didn't work with the iptables rules supplied in the wiki. I instead used this: iptables -t nat -A PREROUTING -i wccp0 -p tcp -m tcp --dport 80 -j DNAT --to-destination 192.168.0.21:3128 I am so sorry to have wasted your time, but you both have taught me a lot and hopefully I won't need anymore help with this issue. :) Thanks again!
