RE: [Openvpn-users] OpenVPN with XP client - can ping both ends but do little else !

["Conor Rafferty" <cr@xxxxxxxxxxxxx>]

Thanks Leonard,

How do I do this ?

Hold on - let me see if I work it out for myself...
If I am running OpenVPN in "dev tap" configuration with network bridging, I
can ping the VNC Server using its private VPN address (e.g. 192.168.0.2) -
- so I merely point VNC Viewer (or web browser client) to this address ?
(192.168.0.2)

Sounds really cool, elegant, simple, and secure !
too good to be true ? or is it....

Ah, one query - will there be a performance issue running VNC thru'
OpenVPN - i.e. all that extra switching / routing / tunnelling /
translation - will that add any significant delay onto the transmissions ?

I would recommend that you use VNC over OpenVNC to gain the security
of OpenVPN.  MS remote desktop works over OpenVPN as well.

I have theses running nearly continously.

P.S. I use UltraVNC on windows and TightVNC on Linux.
