Ok, can you also confirm that your teredo is not at fault. I have no ability to test wired over there. If you try the (hotel) wifi you end up on a different network segment, does that work. Can you reach any IPv6 locations apart from your own server by traceroute? Does test-ipv6.com think IPv6 would work for you?

comment:7 Changed 5 years ago by anonymous

Ok, someone is doing teredo and we cannot easily isolate it; will hunt them down.

As far as I know MacOS does not do Teredo. But I guess there is a rogue
IPv6 router. It works over WIFI. Grrr. Either lousy WIFI or lousy IPv6.

On wired I get these router advertisements:

spock$ ndp -n -r
fe80::64:2%en2 if=en2, flags=O, pref=medium, expire=29m31s
fe80::6600:f1ff:feae:d71f%en2 if=en2, flags=T, pref=medium, expire=29m31s
fe80::fa66:f2ff:fe6a:514a%en2 if=en2, flags=, pref=medium, expire=29m31s
spock$

Are these rogues?

WIFI gives me:

spock$ ndp -n -r
fe80::128:2%en0 if=en0, flags=OT, pref=medium, expire=29m55s
spock$

After 25 years we still have not solved these basic issues :-(

The fe80::{8,16,32,48,64,96,128}:[ 1-3 ] is us.

The are a couple of things we can do but we do not have control over the hotel infrastructure. We'll see.
