Slow internet on client
Posted: Thu May 14, 2020 12:22 am
I recently installed SoftEther VPN on a Windows 2012R2 server at work and added a tunnel on the router to connect to SoftEther. Whenever we connect, the ethernet connection for downloads on our client computers slows down a lot.
I discovered that the default route on the client changes to the VPN connection, and therefor we are limited to less than the theoretical office upload speed, which is a lot less than the office download speed. Also, if we have a download running on the client before the connection, it gets aborted when SoftEther changes the default route. Same thing happens if we start a download while connected to the VPN and close the VPN connection.
I found out that after connecting the VPN, if I delete the default route 0.0.0.0 and add a new default route using the client computer's original default route before the connection, it works exactly as I want it to work. New network connections avoid the VPN route and downloads do not get aborted when starting or stopping the VPN connection.
Is there a option setting either on the SoftEther server and/or the client that I am missing? I looked but couldn't identify anything that looked promising.
Many thanks if somebody has a solution to this.

Mark
