I have just setup a new single WIn2012 R2 as a Direct Access server, only using IPHTTPS.

So far, the config looks ok, but clients cannot connect to the DA server.

Looking at the clients httpstunnel interface, I got an 0x2746 error (connection closed). Any clues about what that means? DA Client Troubleshooting Tools crashes when I run it on a Win7 client.

The client have the right GPO, URL to DA server and can resolve the correct IP of the DA server.

Yes, all WIn7 Enterprise.

Output from the DA server on the HTTPSTUNNEL interface:
Interface IPHTTPSInterface Parameters
------------------------------------------------------------
Role                       : server
URL                        : https://da.domain.com:443/IPHTTPS
Client authentication mode : none
Last Error Code            : 0x0
Interface Status           : IPHTTPS interface active

Output from the client's HTTPSTUNNEL interface:
------------------------------------------------------------
Role                       : client
URL                        : https://da.brreg.no:443/IPHTTPS
Last error code            : 0x2746
Interface Status s           : Could not connect to IP-HTTPS server, reconnecting

The external IP of da.comain.com is NAT'et to a BIG-IP VIP, which only have 1 DA server in the pool at the moment.
I suspect that BIG-IP is dropping traffic, and I have no option to bypass the BIG-IP due to routing issues.

Anyone who can give me a hint where to start? The BIG-IP is setup by another technician who is not very fluent in special setup like Direct Access, only standard web servers.

Hi xcomiii,

We're facing the same issue (error 0x2746) and also have a DirectAccess cluster load-balanced by F5 BIG-IP.  Could you detail what you changed in BIG-IP's config?  Many thanks,
Brendan

As I understood, the magic was NOT to terminate SSL sessions at BIG-IP, but instead use a perfomance forwarding rule. In other words, just to forward all the traffic to the DA servers without any change/inspection/SSL termination.
