Hello!
I have a little network, one firewall/router.
I want to allow some ips to surf the net, and some are not allowed to leave
the trusted net.
I messed around a lot, and that what i have so far, (but it doesnt work at
all!)

iptables -F OUTPUT
iptables -F INPUT
iptables -F FORWARD
iptables -t nat -F PREROUTING

iptables -P OUTPUT ACCEPT
iptables -P INPUT DROP
iptables -P FORWARD ACCEPT


iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
# IP-Forwarding aktivieren
echo 1 > /proc/sys/net/ipv4/ip_forward

## Test Client
iptables -A INPUT -s 10.10.0.180 -j ACCEPT



Why doesnt it work?
Can u give me an exampel how it does work? THat would be really really
nice!!


Thank you!

Spiekey
