I am new here and i want to say Hi to Everybody!
And I have a questions. I want to write Linux firewall iptables rules. I want to block internet access to all users and allow by MAC addresses. Oh and when someone isn=92t on access list to redirect him to web page with information.
I start writing rules:
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -F iptables -X iptables -t nat -X iptables -t nat -F iptables -P INPUT ACCEPT iptables -P FORWARD DROP
iptables -t nat -A POSTROUTING -s 192.168.2.0/24 -j MASQUERADE
iptables -A FORWARD -m mac --mac-source 00:1F:D0:0D:4A:5A -j ACCEPT iptables -A FORWARD -j ACCEPT -m state --state RELATED,ESTABLISHED
but I don=92t know how to redirect blocked users to web page information.
All the best TomTom
