Hi, I'm desperately trying to set up an IPv6 link to my ISP. This ISP provides native IPv6 along with IPv4.
I tried to follow IPv6 native tutorial (http://wiki.openwrt.org/doc/uci/network6) So far, pppd daemon shows that IPV6 link addresses are negociated: Fri Oct 9 21:57:12 2015 daemon.debug pppd[1891]: sent [IPV6CP ConfReq id=0x1 <addr fe80::7840:507d:15d5:2f8b>] Fri Oct 9 21:57:12 2015 daemon.debug pppd[1891]: rcvd [IPV6CP ConfReq id=0xb4 <addr fe80::0230:88ff:fe04:63d4>] Fri Oct 9 21:57:12 2015 daemon.debug pppd[1891]: sent [IPV6CP ConfAck id=0xb4 <addr fe80::0230:88ff:fe04:63d4>] Fri Oct 9 21:57:12 2015 daemon.debug pppd[1891]: rcvd [IPV6CP ConfAck id=0x1 <addr fe80::7840:507d:15d5:2f8b>] I can ping the local address: root@gateway:~# ping -6 fe80::7840:507d:15d5:2f8b PING fe80::7840:507d:15d5:2f8b (fe80::7840:507d:15d5:2f8b): 56 data bytes 64 bytes from fe80::7840:507d:15d5:2f8b: seq=0 ttl=64 time=0.858 ms 64 bytes from fe80::7840:507d:15d5:2f8b: seq=1 ttl=64 time=0.612 ms I cannot ping the remote address if I does not specify the interface: root@gateway:~# ping -6 fe80::0230:88ff:fe04:63d4 PING fe80::0230:88ff:fe04:63d4 (fe80::230:88ff:fe04:63d4): 56 data bytes ^C --- fe80::0230:88ff:fe04:63d4 ping statistics --- 6 packets transmitted, 0 packets received, 100% packet loss However, if I specify the interface: root@gateway:~# ping -6 -I pppoe-wan fe80::0230:88ff:fe04:63d4 PING fe80::0230:88ff:fe04:63d4 (fe80::230:88ff:fe04:63d4): 56 data bytes 64 bytes from fe80::230:88ff:fe04:63d4: seq=0 ttl=255 time=43.002 ms 64 bytes from fe80::230:88ff:fe04:63d4: seq=1 ttl=255 time=60.694 ms ping is successful, then pinging again w/o the interface does work root@gateway:~# ping -6 fe80::0230:88ff:fe04:63d4 PING fe80::0230:88ff:fe04:63d4 (fe80::230:88ff:fe04:63d4): 56 data bytes 64 bytes from fe80::230:88ff:fe04:63d4: seq=0 ttl=255 time=43.083 ms 64 bytes from fe80::230:88ff:fe04:63d4: seq=1 ttl=255 time=43.194 ms I'm not sure why the router does not seem to know how to reach the remote host, as the address has been negociated with pppd... Moreover, whereas 'wan' interface seems ok: root@gateway:~# ifstatus wan { "up": true, "pending": false, "available": true, "autostart": true, "uptime": 2784, "l3_device": "pppoe-wan", "proto": "pppoe", "device": "nas0", "updated": [ "addresses", "routes" ], "metric": 0, "delegation": false, "ipv4-address": [ { "address": "109.190.73.171", "mask": 32 } ], "ipv6-address": [ { "address": "fe80::7840:507d:15d5:2f8b", "mask": 128 } ], "ipv6-prefix": [ ], "ipv6-prefix-assignment": [ ], "route": [ { "target": "0.0.0.0", "mask": 0, "nexthop": "178.32.37.14", "source": "0.0.0.0\/0" } ], "dns-server": [ "91.121.61.147", "87.98.149.171" ], "dns-search": [ ], "inactive": { "ipv4-address": [ ], "ipv6-address": [ ], "route": [ ], "dns-server": [ ], "dns-search": [ ] }, "data": { } } 'wan6' interface seems always down: root@gateway:~# ifstatus wan6 { "up": false, "pending": true, "available": true, "autostart": true, "proto": "dhcpv6", "device": "nas0", "data": { } } I've not been able to find how to debug this issue, any pointer would be great.
