#1164 fixed Unable to connect to ietf* secured SSID from Moto Z Android device Rick Alfvin ketant@…

For some reason my Moto Z with android does not allow me to add any of the ietf* secured SSIDs.

It is not a connection issue since I have problems in adding itself.

Would appreciate help, if possible.

#1163 pending NAT64 issues panda@… wesgeorge@…
Tested my setup with the NAT64 SSID today for a bit, found a few things that aren’t working. I don’t think that this is specifically a problem with the NAT64 implementation on the IETF network, but rather an interesting failure case I wanted to share that is mostly related to my specific setup.

Without VPN, just on standard NAT64:
Outlook Mac 2011 refuses to connect to exchange server, even after closing and re-opening the app. This is normally reachable externally without a VPN over v4. Unclear if this is somehow a problem with Outlook 2011, I’m thinking maybe it doesn’t support IPv6 <-> Exchange in this version.
Trillian won't connect to AIM, Google Hangouts, FB, or Jabber ( <>) - this might be Trillian, as Hangouts and FB messenger works in the web client inside of Gmail.

With corporate VPN:
VPN connects and establishes a connection to a v4-only tunnel endpoint no problem, authenticates, etc. so far so good.
However, intranet sites are unreachable (“DNS probe finished, no internet” in Chrome), and Outlook still doesn’t work. I also can’t ssh to my jump host via either name or IP.

Relevant info - my company’s VPN is technically misconfigured, in that it allows split tunneling - IPv6 traffic bypasses the VPN when you are connected to a dual-stack network. My guess is that there are two issues here - one is that the provided DNS servers do not have entries for our internal stuff, and it seems like maybe DNS queries aren’t being redirected to the DNS servers that should have been provided by the VPN. The other is that somehow even the stuff that should have a route via IPv4 (i.e. internal 10.x hosts connecting directly via IP to bypass DNS) doesn’t seem to be redirecting over the VPN tunnel as expected. Appears that the VPN client isn’t installing the default IPv4 route when it connects over NAT64, maybe because of the 169.254 address present on the interface it’s using. Some output and other details that might help below.

Software used and versions:
MacOS 10.11.6 (El Cap)
VPN: Junos Pulse Secure, SSL/VPN
Outlook Mac 14.7.7
Chrome 62.0.3202.89
Trillian 6.0 (4)

This is the output for when VPN is active on the dual-stack network and IPv4 default is present:

Rest of the output is when VPN is active on the NAT64 SSID, note missing IPv4 default route:

#1162 pending SSID -nat64 issue with Android 7.0 panda@… sanz@…
Hi guys,

whatever checks does Android when associating to a WiFi, they partially 
fail when connecting to the -nat64 (s. screenshot).
It says "Internet could be not available" (but that's a lie, because 
afterwards everything seems to work by now).
Probably as a consequence of that the WiFi icon displays an exclamation 
mark I can't get rid of even if I reassociate.



Note: See TracQuery for help on using queries.
