* sorry for the other schema, it came out a mess. I hope this one is 
understandable.

hi:

I have this 2 boxes set up like this:


              2020::2/128                       
2020::254/128                3030::254/128
            192.168.0.2/24                 192.168.0.254/24           
192.168.30.254/24

              +-------+   eth0                                eth3   
+-------+
               |          |============ |          |   eth1
               |   A    
|                                                     |   B    | ----  
               |          
|                                                     |          |
              
+-------+                                                   +-------+



   A

# ip r l
192.168.30.254 dev eth0  scope link
192.168.0.0/24 dev eth0  scope link
169.254.0.0/16 dev lo  scope link
127.0.0.0/8 dev lo  scope link

# ip -6 r l
2020::254 dev eth0  metric 1024  mtu 1500 advmss 1440
3030::254 dev eth0  metric 1024  mtu 1500 advmss 1440
(...plus link local and multicast routes)


   B

# ip r l
127.0.0.1 dev lo  scope link
192.168.0.0/24 dev eth3  proto kernel  scope link  src 192.168.0.254
192.168.30.0/24 dev eth1  proto kernel  scope link  src 192.168.30.254

# ip -6 r l
2020::2 dev eth3  metric 1024  mtu 1500 advmss 1440 metric10 64
(...plus link local and multicast routes)

# cat /proc/sys/net/ipv4/ip_forward
1
#cat /proc/sys/net/ipv6/conf/all/forwarding
1


The problem is that i can ping 192.168.30.254 from A, but i can't ping 
3030::254 from A, anyone has a clue why this happens? Is there any 
feature i need to turn on or anything misconfigured? Why does it work 
for IPv4 but not for IPv6?


A -> B

# ping 192.168.30.254
