Can see login page when accessing apple.com, but after login the client PC is unable to surf the Internet.

As the client PC is able to see the login page when accessing apple.com, this test will eliminate the possibility of problem in both DNS and Offloading.

First, assuming the NAT within your FirstSpot is on (default setting. Note that if you turn off NAT within FirstSpot, you need to add a return route in your next-hop router or use ProxyARP feature within FirstSpot, otherwise you will have similar symptom). In that case, most likely you have problem in routing. Please try the followings:

1) make sure only the Internet/Public Network Interface (i.e. network card that connects to the Internet side) has Default Gateway. Windows will use Default Gateway setting to determine the routing table, and setting more than 1 Default Gateway will confuse routing. The easiest way to check the Default Gateway for all of your network cards is to use command ipconfig.

2) Start "Routing and Remote Access" (RRAS) service manually as a test, does Windows generate any error (check the Windows Event Viewer also)? Remember to stop "The Routing and Remote Access" service after the test. (i.e. The "Routing and Remote Access service" should be "not started" and Starting type should be "manual" before you start FirstSpot.)

Note that if you install FirstSpot v5/v6 on Windows Vista or above (with NAT on), ICS (Internet Connection Sharing) is used instead of RRAS. For FirstSpot v7/v8 install on Windows Vista or above, FirstSpot will use its own NAT driver.

3) Now try to start FirstSpot. After FirstSpot is started successfully, check the "Routing and Remote Access" service again (the status should be "Started"). Verify the Windows Event Viewer again for any suspicious error.

4) Another thing you can try to enable routing explicitly. Note that RRAS should enable routing already when started (except in Windows 10). Please run the following command in your Command Prompt (need to right click and "run as administrator"):
