Well, with current settings it's not possible indeed. But, if you have administrative control over GPOs forcing proxy settings in IE, you could fix the problem like this: 1 enforce Auto proxy and put either a DNS or DHCP entry that points to the PAC URL in the office LANs; 2 Remove any direct access between users and internet in the office (of course); 3 Add a proxy in the NC Connection Profile you want to use, quite possibly the very same as in step 1 Now, all mobile users will use Auto detected proxy settings. At home, there's probably no wpad.office.lan DNS entry, nor a DHCP server supplying such a url, so: OK. If there is: no conflict, OK^2. If they _are_ at the office, there's no internet connection availbe: OK once more. Autodetect supplies them with wpad.office.lan, and that's fine too. Now they try to connect to NC on the SA: as mentioned before, this works fine. And now, by their assigned role's profile the are assigned a proxy too. By enforcing all internet-targeted traffic through the tunnel, combined with the proxy, you should theoretically have solved your problem and even better: your road warriors can use IE on the road as well.
