| #1239 | fixed | ipv6 wonkiness | ||
| Description |
howdy!
I noticed that i can't ping (ipv6 ping) a bunch of things like:
~$ ping ipv6.google.com
PING ipv6.google.com(sin10s02-in-x0e.1e100.net (2404:6800:4003:80d::200e))
56 data bytes
^C

$ ping www.google.com
PING www.google.com(sin10s02-in-x04.1e100.net (2404:6800:4003:80d::2004))
56 data bytes

$ ping mailserver.ops-netman.net
PING mailserver.ops-netman.net(mail-v6.ops-netman.net
(2606:700:e:550:b00b::b00b)) 56 data bytes
^C

I thought (until the third item) that this was my fault ... but! I think
it's not (at least not for the reason I originally thought)... I also can't
connect over ipv6 to services which SHOULD be running, like:
$ telnet ipv6.google.com 443
Trying 2404:6800:4003:80d::200e...
^C
$ telnet www.google.com 443
Trying 2404:6800:4003:80d::2004...
^C
$ telnet mailserver.ops-netman.net 22
Trying 2606:700:e:550:b00b::b00b...
^C
I CAN connect to these from a point not on the current IETF network:
$ telnet mailserver.ops-netman.net 22
Trying 2606:700:e:550:b00b::b00b...
Connected to mailserver.ops-netman.net.
Escape character is '^]'.

| #1187 | pending | ipv6 temp address rotation(?) on win10 breaks long-lived connections | ||
| Description |
Hello,
My problem probably isn't due to the ietf-nat64 network, as I've seen
this happen in other v6 enabled networks as well, but here goes anyway
as a FYI:
I'm using the ietf-nat64 wifi with a Windows 10 (1709 update) client and
my long-lived v6-tcp connections like ssh (putty client with keepalive
set) tend to hang after some time. This has also happened to me reguarly
on earlier versions of Windwows. For the hangup to occur it usually
takes between tens of minutes to about an hour or two. After I login to
the same host again, I see the v6 address I'm coming from has changed
from the previous address.
So it looks like windows, for some reason or another, is disabling the
old temp v6 addresses while there still are tcp connections open. It
should not work like this, but I guess it could just be a feature in
windows.
Other than long-lived tcp connections breaking for me, the nat64 network
seems to be working fine. Maybe you could switch within the next couple
of meetings to a v6 / nat64 mode on the default "ietf" network and
provide native v4 only on a non-default ssid.
Here's an excerpt from an ipv6 enabled server log (timestamps utc+2):

This is from a v4-only server log, probably only the second last line
was from a connection terminated due to address change:

| #537 | fixed | ipv6 routing up yet? | ||
| Description |
I'm sitting in my hotel room, using the wired Ethernet connectivity which apparently comes from the IETF right now, unless the hotel offers me IPv6 addresses... But there doesn't appear to be IPv6 connectivity.
You probably knew this, and are building the network as we speak. But just in case you didn't I'm reporting it...
