Hi
I am trying to configure the iptables after i have configured bridge. The
kernel is 2.4.14.What i am trying to do is to restrict or drop all packets
coming from the interface eth1.
The setup is as follows :
Network(192.168.1.0) <------> (192.168.1.1)Router A
(172.16.0.2)(NAT)<-----------> Bridge <-----------------> (172.16.0.1)Router
B(83.x.x.x-public)(NAT) <------------------->Internet
The interfaces on the bridge are configured 0.0.0.0 and i have assigned an
IP Address to the Bridge br0 - 172.16.0.3
I have given a statement iptables -A INPUT -j DROP .- this statement blocks
all traffic coming to the box .
iptables -A FORWARD -j DROP does not block traffic flowing from the network
to the outside world ie internet.If i ping www.yahoo.com from the Router A
or from a laptop on the 192.168.1.0 network, it still works and i am still
able to browse the internet from the laptop.
What is missing here ??
