Setup Routing Settings for Multiple VPNs Connection

Introduction

If the line that can access the server is limited, VPN is often used to clear it, even in simple way, VPN is used to access the company server during telework, and it connects to the VPN server on the Internet to fix the connection source IP. By the way, if you use a lot of VPN connections , then the routing will be messed up, and you may not be able to access the target server even though you are connected to the VPN.
