Plusnet Gateway dropping IPv6 tunnel data

[#1]

The Gateway with IP 195.166.130.254 appears to be dropping or blocking 6in4 tunnel traffic from Hurricane Electric. This results in timeouts for IPv6 connections.

Is anyone else seeing this behaviour who are also with HE?

@RPMozley  is your H.E. tunnel endpoint in London the server "tserv1.lon2" ?

- that device is currently showing a warning - "New tunnels temporarily disabled due to high usage"

The other H.E. London endpoints "tserv5.lon1" and "tserv17.lon1" are not reporting any issues.

I would have tried to help you by attempting to reproduce your problem on my setup, having used an H.E. tunnel for about eleven years, but I now have native IPv6, and my H.E. tunnel config has been cleared out of my router.

If you are on "tserv1.lon2", then just go into your Tunnelbroker account, change the endpoint to one of the others, then update the tunnel IP address in your router to match. (that's what I had to do when my "tserv5.lon1" endpoint went down for a month).

I’m aware of that server issue but my tunnel is to “5.1” and not “1.2”.
The tunnel works perfectly fine on my current gateway server “195.166.130.251”.
There seems to be something different with the 195.166.130.254 gateway.

Thanks for your input though @outcast

Gateway "195.166.130.255" is also showing the same odd behaviour as the one I mentioned earlier.

Now I have to try and get on a different gateway, which isn't always easy, to get IPv6 traffic flowing again.

The only person on here that I can think could look at this for you is  @dave  ?

@RPMozley   what part of England are you in ?

I'm not far from London, and both my Plusnet gateway and Hurricane Electric tunnel gateway were in Telehouse London, so likely located in the same building ? - and if anything I had better internet connectivity over the HE IPv6 tunnel than I got on native Plusnet IPv4 routes,  certainly less hops, near identical speed, and just a 0.3ms latency penalty.

I'm wondering if you were in a different part of the country, whether your Hurricane Electric endpoint might be in  Manchester,   Leeds,  Slough,  Edinburgh,  and 'might' be a transit issue that could be region specific to your nearest Plusnet gateway ?

Hurricane Electric's UK locations are listed on page 2 of this map - http://he.net/HurricaneElectricNetworkMap.pdf

Certainly Dave would probably be able to find out, if he's still around and not moved on to other areas or companies.

I don't think in this case, location is a factor because I believe all PN gateways are located in London. But for info we're located in Gloucestershire.

I think it was still possible to ping an IPv6 address directly but times out with a domain name. I'll have to do some more testing once we get kicked onto a "problem" gateway.
