Problem:

After a VPN connection is established, all outgoing connections are 
allowed, even if the Windows Firewall setting for outgoing connections 
is set to "Block".

To Reproduce:

1. Open "Windows Firewall with Advanced Security", click on "Windows 
Firewall Properties", in the [Domain Profile] tab, set "Outbound 
connections" to [Block], in the [Private Profile] tab, set "Outbound 
connections" to [Block], in the [Public connections] tab, set "Outbound 
connections" to [Block], press [OK] to close window.
2. Observe that your favorite web browser cannot connect to any websites 
anymore.
3. Connect to any gateway.
4. Observe that your favorite web browser now can successfully connect 
to arbitrary websites.

Expected behavior:

For 4., we should observe that the web browser still cannot connect to 
any websites.

VPN Client Version = 2.2.2
Windows OS Version = Windows 10, Version 1511
Gateway Make/Model = n/a
Gateway OS Version = n/a
