Have a proxy server with squid installed. Want to configure iptables so as to allow a single ip in lan to access internet directly without directing the traffic through squid. the following works to masquerade traffic but how to filter so that only one ip is given access iptables -t nat -A POSTROUTING -o eth1 -j MASQUERADE
the current iptables configuration is default. It does't have any rules applied.The squid server does its usual of providing proxy internet service.
currently i am studying iptables, so not a expert in it.So kindly be specific to rules that should be applied.
