Hi,
First of all, thank you for providing the tunnel broker service for free! I was able to set it up on my router and all my LAN devices get assigned routed /64 IPv6 addresses and can access IPv6 internet. However I noticed a strange issue only on my Windows 10 machines. I was not able to ping and traceroute (tracert) times out after three hops at ve422.core1.nyc4.he.net:
ping -6 ipv6.google.com
Pinging ipv6.l.google.com [2607:f8b0:4006:805::200e] with 32 bytes of data:
Request timed out.

tracert ipv6.google.com
Tracing route to ipv6.l.google.com [2607:f8b0:4006:805::200e]
over a maximum of 30 hops:
1 <1 ms <1 ms <1 ms [Client endpoint address of my tunnel]
2 6 ms 7 ms 5 ms tunnelXXXXXX.tunnel.tserv4.nyc4.ipv6.he.net [2001:470:XXXX:XXXX::1]
3 4 ms 3 ms 3 ms ve422.core1.nyc4.he.net [2001:470:0:5d::1]

7 * * * Request timed out.
8 * * * Request timed out.
9 * * * Request timed out.
10 * * * Request timed out.

For comparison the same requests worked out just fine on both Linux and Mac hosts in the LAN:
$ ping ipv6.google.com

The Windows 10 host can browse the IPv6 internet without any issues (though ipv6-test.com says that ICMPv6 timed out on it even though I have configured the firewall properly both on my router and on the Windows host. When I had native IPv6 through my previous ISP with the same firewall rules the Windows host can receive ICMPv6 from ipv6-test. All my other hosts pass ipv6-test.com with 20/20 as well).
Any idea what could be the problem here? I tried to spin up a Linux VM on the windows host with bridged connections and ping and traceroute worked fine on it, so I know that there shouldn't be any issue at the link level at least.
Thanks!
