With OpenVpn you can open 2 or more vpn channels simultaneously. Naturally the 2 networks in connections will have to be different.
When you launch a connection with OpenVpn, it engages the Tab Adapter network card that was installed during the installation of OpenVpn. If you try to open a new connection with OpenVpn you will be notified that the TabAdpater tab is already in use.
To solve the problem the trick is to install a new TabAdapter. When you launch the second connection OpenVpn will use this second card.
Install a TabAdapter
