Hi list, I am relatively new to iptables i am trying this iptables -A PREROUTING -t nat -i eth0 -d 202.75.112.3 --dport 8080 -j REDIRECT --to-port 3128 . Now the problem is it does not get redirected , if i remove the -d part , it works just fine but i do not want to redirect for any destination , but only if request comes for a particular destination . Is there any thing wrong that i am doing , or do i have to use some different chain or ruleset , please help
