Sometimes, you may keep connected in VPN network. You can connect to VPN with Windows VPN service but you always click connect button manually when start-up computer or after deactivate the sleep mode. It is pretty tired.
So I was finding how to autoconnect to VPN without any control, but there are no good program on Windows.
But I found the way to make keep connected on my ASUS router.
Actually, I can connect my ASUS router to VPN server with VPN client function in my Asus router admin page, but it is not stable. After few days, Internet connection is not working occasionally.
But This way is more reliable than that way.
You can also setting up your Asus Router as a VPN client in WAN menu.

5. Enter the VPN ID and Password at PPP Username and Password.
6. Enter the VPN Server address at VPN Server.
7. Click the Apply button.
Go to next step
1. Click the LAN menu located at left side of the admin page.
2. Click the Switch Control button located at top of the page.
