How do you know that a particular interface has access to the Internet?
For example, I have 5 exit points in the interent, LAN, vpn connection and 3 usb modems.
Windows in Center Network and Sharing Center is able to identify and write beside each interface - "Internet"
How to do the same thing to me. Maybe there Api or through wmi?
I would like to get around this table:
Lan - no internet
vpn - no internet
1 modem - Internet
2 modem - Internet
3 modem - Internet
