Hi
I would like to enable ipv6 forwarding . i have ipv6 module loaded.
I added net.ipv6.conf.all.forwarding=1 in /etc/sysctl.conf .
i tried reboot , did ‘service network restart’ .
.
Also I tried
sysctl -w net.ipv6.conf.all.forwarding=1
and
echo 1 > /proc/sys/net/ipv6/conf/all/forwarding
and rebooting and ifdown& ifup interfaces.


But stiilll i dont see the IPv6 being forwarded between two inyterfaces (i am using tcpdump to see).

Details:
# modprobe -c | grep ipv6
alias net-pf-10 ipv6
alias ipv6 on
...
..


#cat /proc/version

# cat /etc/redhat-release

First thing I'd check is the rest of the equipment. Is everything (router, switch) ipv6 capable?
