DirectAccess client can't connect
- by odd parity
I've set up a DirectAccess server on Windows Server 2012 at my workplace. I'm using a Windows 8 Enterprise client to connect to it. It works fine over a mobile connection, but it fails when connecting from home. I've ruled out the firewall/router as the culprit as the issues persist when connecting the laptop directly to the cable modem.
I'm not sure where to begin to debug this, does anyone have any pointers? Both Teredo and IPHTTPS interfaces are up (although as the server is behind a NAT and we only have 1 public IP I understand that IPHTTPS is the only protocol that will be used).
The IPHTTPS tunnel also seems to be connected:
netsh interface httpstunnel show interfaces
Interface IPHTTPSInterface (Group Policy) Parameters
------------------------------------------------------------
Role : client
URL : https://redacted:443/IPHTTPS
Last Error Code : 0x0
Interface Status : IPHTTPS interface active
however the DirectAccess link can't be activated - get-daconnectionstatus cycles between
Status : Error
Substatus : CouldNotContactDirectAccessServer
and
Status : Error
Substatus : RemoteNetworkAuthenticationFailure
Any suggestions on how to attack this are appreciated!
