Repeater mode and ipv6

[Bo Simonsen]

Hi

I have my RT-N66U running in repeater mode. It works out great, I connect with a twisted pair cable and the
performance is way better than running with WiFi on the laptop. However, I get a ipv6 address

14:06:44 bo@bo-suse ~ > ip -6 addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 state UNKNOWN qlen 1
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000
    inet6 2a06:4000:197e:0:56ee:75ff:fe75:9119/128 scope global dynamic 
       valid_lft 3668sec preferred_lft 1795sec
    inet6 fe80::56ee:75ff:fe75:9119/64 scope link 
       valid_lft forever preferred_lft forever
14:06:46 bo@bo-suse ~ > ip -6 route
2a06:4000:197e:0:56ee:75ff:fe75:9119 dev eth0  proto kernel  metric 256  expires 3558sec pref medium
2a06:4000:197e::/64 dev eth0  proto ra  metric 100  pref medium
2a06:4000:197e::/48 via fe80::222:7ff:fe5d:120b dev eth0  proto ra  metric 100  pref medium
fe80::/64 dev eth0  proto kernel  metric 256  pref medium
default via fe80::222:7ff:fe5d:120b dev eth0  proto static  metric 100  pref mediu

But when I try pinging my default gateway no response (if I connect directly to the router, I get response):

14:09:05 bo@bo-suse ~ > ping6 -I eth0 fe80::222:7ff:fe5d:120b
PING fe80::222:7ff:fe5d:120b(fe80::222:7ff:fe5d:120b) from fe80::56ee:75ff:fe75:9119 eth0: 56 data bytes
^C
--- fe80::222:7ff:fe5d:120b ping statistics ---
11 packets transmitted, 0 received, 100% packet loss, time 10079ms

Anybody having any hints? IPv4 works fine.
