Witam. Mam problem z rozsyłaniem ipv6 po lanie w mr-3420. Posiadam Openwrt 15.05 Chaos Calmer z eko one. mam tunel z he.net. W openwrt pingi idą bez problemu :
PING google.pl (2a00:1450:401b:801::2003): 56 data bytes
64 bytes from 2a00:1450:401b:801::2003: seq=0 ttl=56 time=31.329 ms
^C
--- google.pl ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max = 31.329/31.329/31.329 ms

Jednak na komputerze mam :
[root@localhost tomasz]# ping6 google.pl
connect: Network is unreachable
a wynik ip :
[root@localhost tomasz]# ip addr show enp0s7
