Subject: GRE protocol .
Date: Fri, 30 Apr 2010 12:49:22 +0530	[thread overview]
Message-ID: <s2ycfeab66d1004300019ge75963b8vc3243c7d947e850e@mail.gmail.com> (raw)

Router wan interface is eth1 and lan interface is eth0 .

iptables  -A INPUT  -m state --state ESTABLISHED , RELATED  -j ACCEPT .
iptables  -A INPUT  -i eth1 -j DROP .
iptables  -A INPUT  -i eth0 -j ACCEPT

iptables  -A FORWAR -m state  --state ESTABLISHED , RELATED  -j ACCEPT
iptables  -A FORWARD -i eth0 -o eth1 -j ACCEPT
iptables  -A FORWARD -i eth1 -o eth0 -j DROP .

I dont have pptp connection  tracking module installed .  But i can
see GRE protocol packet comed from wan gets routed and reaches my
client machine   connected  to eth0 ?.

I can see message id is 0 in GRE packet .
I have only pptp connection .

Any hint is really appreciated ?

Thanks,
Ratheesh
