[solved] IPv6 with RT-AC68U
Solved in terms of 'not related to the router'.
Hi
Today I set up my RT-AC68U for IPv6. (For the record, it's on FW 3.0.0.4.376_3626 .)
My ISP does support native IPv6 and assigns /48 subnets through DHCPv6-PD.
It is possible to ping6 within the network (using the 2a02:XXXX:4a06:: and the fe80:: addresses), but it's not possible to ping6 any external service (e.g. google.com) from any of the clients in the network except from the router itself (i.e. ssh into the router and ping6 google.com works perfectly.)
This is the (anonymized) config:
Every client receives it's own /64 subnet out of the 2a02:XXXX:4a06:: subnet though SLAAC as it should.
To me it looks strange that the WAN IPv6 is out of a completely different subnet than the LAN IPv6 prefix,but the 2a02:XXXX:4a06::/48 net is routed back to that WAN IPv6, so it might actually be okay. (I've checked that with a tracepath6 from an external server.) Actually I'm not so sure about that second part anymore. I need to check that with my ISP first.
Does anyone has an idea why it's not working or has anyone at least fully working native IPv6? What are your settings?
Cheers,
Chris
PS: Here is the routers IPv6 routing table, maybe this could lead to the issue. (I'm helpless here
