I can't access anything on the WAN side using ipv6 unless I ping the target IP address from the RB5009. If I have a ping going from the RB5009 I can ping from hosts on the WAN and even score 18 out of 20 on ipv6-test.com. ipv6 keeps working for whatever I was pining for a short time after stopping the ping, maybe 20s or so.
When the ping isn't running on the router I get Address Unreachable errors from the router. I checked with the packet sniffer and nothing goes out on the WAN side. The only icmpv6 traffic is link local stuff, mostly multicast. I've also noticed that I never see any "reachable" routers in the neighbor list. I could swear there use to be one back when ipv6 was working.
Anyone have a guess as to what could cause this?
