Sorry for my English.
I have Linux as VPN terminator (pptpd). Some computers in LAN should not
have access to the server (Over GRE). So I just put:
iptables -I INPUT -s 192.168.1.1 -j DROP
And nothing.
I put:
iptables -I PREROUTING -s 192.168.1.1 -p 47 -j LOG
iptables -I PREROUTING -s 192,.168.1.1 -j LOG
and there are no messages from kernel when tunnel is up.
What wrong? Why some IP-level packets travel behind my filter?
