Hi XQZR

    Yes setting the MSS lower works. Hopefully I get no large UDP packets.

Thank you

Questions & Answers / Re: paris not routing IPv6?

It turns out the tunnelserver works, only my tunnel is affected. The best guess is that something along the route must have started to block protocol 41 :-(

I need to migrate to another solution... Thanks for the stable service for a very long time now, and thanks all the fish!

Looking at my wireshark capture I am missing the ICMPv6 packet to big message from the HE tunnel endpoint. Can someone from HE confirm they get send ?

Thank you

Questions & Answers / paris not routing IPv6?

Last post by lmamane - July 28, 2025, 04:42:12 AM

My tunnel over tserv10.par1 / tserv1.par2 seems not to route IPv6 anymore; it shows as "up" on https://tunnelbroker.net/status.php/ It worked this morning and I didn't change anything... Are other users of that tunnel server encountering the same?

I can ping the server tunnel endpoint over IPv4.
I can ping the server tunnel endpoint FROM ANOTHER IPv6 host but NOT from the tunnel.
I cannot ping anything IPv6 over the tunnel, nor the client tunnel endpoint from another IPv6 host.
With tcpdump, I do see IPv4 packets with protocol IPv6 (41) outgoing from my machine to the IPv6 tunnel endpoint, but nothing coming back.

This is a powershell script, that is working fine in scheduler in Windows.

It updates two dynamic AAAA records every 5 minutes from the scheduler starting from windows laod using account 'NT\Network Service'.

I have allowed to run 'unsigned powershell scripts'.
