Hi,
I receive an email form tunul robot who infor me Tunnel endpoint didn't ping
I have lunch an tcpdump -i ppp0 > tcpdump.log
grep "212.19.192.219" tcpdump.log
08:30:54.906956 212.19.192.219 > 62.212.103.124: gw-715.ams-02.nl.sixxs.net > cl-715.ams-02.nl.sixxs.net: icmp6: echo request (DF)

I have test to add this iptables rules :
iptables -t nat -A POSTROUTING -s 212.19.192.219/32 --proto ! 41 -o ppp0 -j MASQUERADE
212.19.192.219 is the ipv4 of my pop
I would like ask if is the good rules ?
How i can verify if i rerouting the ICMPv6 echo-reply through another tunnel ?
thx in advance for your help

Read the rest of the forum there have been enough people showing how it works.
Also you might want to consider doing a 'man iptables' as the above -s switch is complete nonsense.
