Hello.
Tunnel T3686 is up and working already for a few weeks (pinging my tunnel endpoint is OK from lg.version6.net), but tunnel status showing that it is down.
How to avoid tunnel auto-disabling, if it is working, but POP status is down?
BTW, Reverse DNS Delegations also seems to be not working for my R1716 subnet.
I hope, that it's temporary problem and will be fixed sooner or later.

Hello,
please check if your firewall accepts arbitrarily sized ICMPv6 echo packets (type 128) from the PoP. I was bitten by this recently, as the size of the packets has apparently increased. The ip6tables rule
ACCEPT ipv6-icmp <your PoP IPv6>/128 anywhere ipv6-icmp echo-request
solved the problem for me. (I have no idea how to fix your reverse DNS delegation problem, however.)
Regards,
Christoph Schulz

As the firewall FAQ simply states that one should accept ICMPv6 packets from the PoP, if you filter out packets based on size indeed you might break things, just don't filter ICMP then.
