Transparent Squid Proxy Server

[Reet Vyas <reet.vyas28@xxxxxxxxx>]

I am trying to configure transparent squid proxy on ubuntu 14.04 Server and squid 3.3 version I am using

My Lan and Wan settings

my squid.conf file

but when I use 192.168.0.200 in my client machine as gateway ... internet is not working and I cant see logs in access.log

But when I use this IP in my browser it is working and showing logs but with my tplink router  gateway i.e 192.168.0.1.

IPTable rules :
num  target     prot opt source               destination        
1    DNAT       tcp  --  anywhere             anywhere             tcp dpt:http to:192.168.0.200:3128
2    REDIRECT   tcp  --  anywhere             anywhere             tcp dpt:http redir ports 3128

Chain INPUT (policy ACCEPT)
num  target     prot opt source               destination        

Chain OUTPUT (policy ACCEPT)
num  target     prot opt source               destination        

Chain POSTROUTING (policy ACCEPT)
num  target     prot opt source               destination

Please tell me what I am missing in IPtables and squid3 configuration . I tried both transparent as well as intercept option but I think I have issue with iptables or may be configuration issue.
