I have few system with ipv6 addresses. I want to forward request from one system to another. hence I kept the option
net.ipv6.conf.all.forwarding = 1
in sysctl.conf
but the request is not getting forwarded as it is doing in ipv4, its giving me the error in booting also. net.ipv6.conf.all.forwarding 1 is an unknown key
sysctl -w
?grep IPV6 /boot/config-$(uname -r)
? Where config-??? is the path to the kernel config file.
