-

 

1. 



Test Result:

When SC detects PC is on Untrusted network, it prompts to ask the user to connect to VPN.

When SC detects PC is on Trusted network, it doesn't prompt.






















2. Enable Always on

   



Test result
User can disconnect VPN, but only can access www.google.ca and DNS server 203.0.113.2

When ASA is not reachable, "Connect Failure Policy" kick in, with "Open" policy, user is able to access any websites.







When ASA is reachable again, prompt user to connect, at this moment, again, only  www.google.ca and DNS server 203.0.113.2 are able to connected.





3. Captive Portal

By default, captive portal detection is enabled, as soon the PC connects a Open wifi with Captive portal,  Cisco Secure Client - Web Browser is popup, in the lab, it is display a blank page, depends on configurations in profile, the browser window may disappear in a second or stay open.  Captive portal detection need be disable if we don't want to see this browser.

Windows 10 has internal mechanism to detect if PC is connected to Internet,  when Open WiFi is connected, Windows 10 will launch default browser to www.msftconnecttest.com, then it will be redirected to Captive Portal to let use login via web.
