Re: How can I only allow certain MAC/IPs to access the netwo

First allow your MAC address then deny all others to input to your server /sbin/iptables -A INPUT -i ethx -p tcp -s 192.168.x.x/x -d x.x.x.x -m mac --mac-source XX:XX:XX:XX:XX:XX -j ACCEPT /sbin/iptables -A INPUT -i ethx -p tcp -s 192.168.x.x/x -d x.x.x.x -m mac --mac-source XX:XX:XX:XX:XX:YY -j DROP

how to deploy squid as transparent proxy

Hi,

in squid you should allow your lan users and deny all others

and in iptables

MODPROBE=/sbin/modprobe
$MODPROBE iptable_nat
$MODPROBE ip_tables


IPTABLES -t nat -A POSTROUTING -o eth0 -s 192.168.0.0/24 -j SNAT --to-source 192.168.1.51

OR
$IPTABLES -t nat -A POSTROUTING -o $EXTIF -j MASQUERADE
