Jak spustit 2 klienty OpenVPN [vyřešeno]

[RNA]

Mám takový problém s OpenVPN, ono je to spíš na dotaz na nějaké Wokenní fórum.  
Z jednoho počítače (WXP) se chci připojit současně na 2 servery s OpenVPN - oba běží na Xubuntu.
Ono to chodí, ale vždy jenom jedno, když chci současně, tak to na tom druhém pokusu zařve, že síťové rozhraní je již používáno.
Asi tak:

No tak, ono skutečně je, ale tak bych očekával, že se vytvoří ještě jedno.
Alespoň v Xubuntu to tak funguje, na jednom s těch serverů běží kromě serveru ještě klient a vesele koexistují vedle sebe:

Klidně se tam proklikejte přes "přidat nový hardware",

BTW oficiální dokumentace : http://openvpn.net/index.php/open-source/documentation/install.html?start=1

Notes -- Manual Install/Update/Uninstall of the TAP-Win32 kernel driver

This is best done using tapinstall.exe, a utility based on a DDK sample which is distributed with the self-installing form of OpenVPN on Windows. Cd to the directory which contains OemWin2k.inf and tap0801.sys.

To install:

    tapinstall install OemWin2k.inf TAP0801

To update:

    tapinstall update OemWin2k.inf TAP0801

To uninstall:

    tapinstall remove TAP0801

By installing multiple times, you will create additional TAP-Win32 adapter instances, which can be used for multiple concurrent VPN tunnels.

It is also possible to install using Control Panel -> Add New Hardware, and it is possible to uninstall using Control Panel -> System -> Hardware -> Device Manager.

Prima, funguje to. 
Jen jsem to musel instalovat takto: tapinstall install OemWin2k.inf TAP0901, asi je v instalačce OVPN vyšší verze driveru.
