I have 2 boxes that act as IPv6 routers. One with 2 physical
interfaces, the other with 6 vlan ''interfaces'' on one physical
interface
plus a second physical interface. On both systems I have in
/etc/sysconfig/network
IPV6FORWARDING=yes
But if I have my ''basic'' ip6tables service running, only ICMP
messages
get through. Since both of these boxes are Centos based, I can''t use
the new shorewall6 that requires at least FC9 (both boxes have shorewall
for IPv4 routing controls).
Is there a ''simple'' rule to add to forward all IPv6 traffic
between the
interfaces, with the other rules only impacting traffic for each host
itself?
