Question about WARNING message: You have specified redirect-gateway and redirect-private at the same time
Posted: Fri Mar 11, 2022 4:32 am
Hi, everyone.
I am trying to create original VPN software with openvpn-2.5.3 source code.
I have connected VPN normally to OpenVPN Access Server 2.9.5 with open-sourced OpenVPN client ,but some error messages are displayed on openvpn client log as follows.
I would like to fix the following error.
How can I fix this error?
