The Internet Explorer 11 desktop application will progressively redirect to the faster, more secure Microsoft Edge browser, and will ultimately be disabled via Windows Update. Disable IE today.
Consider the following scenario:
You configure Internet Explorer 10 not to use a proxy.
You connect the computer to a virtual private network (VPN) by using a VPN client that does not support IPv6.
You configure a proxy in the VPN connection settings in the Internet options dialog box.
You try to use Internet Explorer 10 to open a website.
In this scenario, Internet Explorer 10 does not use the proxy settings in VPN connection to establish the connection.
This issue occurs because Windows does not use IPv4 proxy settings when an Internet connection is available as IPv6 for VPN connections. Therefore, proxy settings for VPN clients that do not support IPv6 are not used.
