dd-wrt and ipv6 - no connection inside LAN
[ru] Carmen Sandiego on Wednesday, 28 April 2010 11:10:59
Hi! I have a problem with IPv6 connection inside lan. I configured dd-wrt using that script - http://dd-wrt.com/forum/viewtopic.php?t=69448, changing vlan1 with ppp0 (i have pppoe adsl connection) in fact, i can use ipv6 from router (tried ping6 and connection to ipv6-based freenode servers), but from inside LAN machines i get Network unreachable. All machines have IPv6 addresses (radvd is working) Here is route table from router root@lex-router:~# ip -6 route 2001:15c0:65ff:3e2::/64 via :: dev sixxs metric 256 expires 42948376sec 2000::/3 via 2001:15c0:65ff:3e2::1 dev sixxs metric 1 expires 42948377sec fe80::/64 dev br0 metric 256 expires 42948363sec fe80::/64 dev vlan0 metric 256 expires 42948366sec fe80::/64 dev vlan2 metric 256 expires 42948366sec fe80::/64 dev eth0 metric 256 expires 42948366sec fe80::/64 via :: dev sixxs metric 256 expires 42948377sec fe80::/64 dev vlan1 metric 256 expires 42948701sec fe80::/64 dev eth1 metric 256 expires 42948702sec ff00::/8 dev br0 metric 256 expires 42948363sec ff00::/8 dev vlan0 metric 256 expires 42948366sec ff00::/8 dev vlan2 metric 256 expires 42948366sec ff00::/8 dev eth0 metric 256 expires 42948366sec ff00::/8 dev sixxs metric 256 expires 42948377sec ff00::/8 dev vlan1 metric 256 expires 42948701sec ff00::/8 dev eth1 metric 256 expires 42948702sec default via 2001:15c0:65ff:3e2::1 dev sixxs metric 1 expires 42948377sec default via 2001:15c0:65ff:3e2::1 dev sixxs metric 1024 expires 42948528sec unreachable default dev lo metric -1 error -128 and from sample client 2001:15c0:65ff:3e2::/64 dev wlan0 proto kernel metric 256 expires 82038sec mtu 1480 advmss 1420 hoplimit 0 2002:4f8b:8b94:28e::/64 dev wlan0 proto kernel metric 256 expires 77784sec mtu 1480 advmss 1420 hoplimit 0 fe80::/64 dev wlan0 proto kernel metric 256 mtu 1480 advmss 1420 hoplimit 0 what i am doing wrong?

2001:15c0:65ff:3e2::/64 via :: dev sixxs metric 256 expires 42948376sec
[..]
and from sample client
2001:15c0:65ff:3e2::/64 dev wlan0 proto kernel metric 256 expires 82038sec mtu 1480 advmss 1420 hoplimit 0
2002:4f8b:8b94:28e::/64 dev wlan0 proto kernel metric 256 expires 77784sec mtu 1480 advmss 1420 hoplimit 0
You only have 2001:15c0:65ff:3e2::/64 which is a TUNNEL prefix, you cannot use it on your wireless. You need to request a subnet. Also note that additionally to that you also seem to have 6to4 enabled (2002:...).
