hi there,

just asking..

>dev-node tap-bridge

you have renamed your network connection to "tap-bridge"..right?

>and it is bridged with network adapter

you mean that you bridge it using windows "bridge" function?

cheers,

michael.

[mrblue]

yes i renamed the tap adapter to "tap-bridge" and it is bridged with network adapter using the windows function.

I have since setup and am currently using the point to point vpn. which is working although not on the same computer i was attempting to setup the bridge on. couldn't get it to work on that computer, gave an adapter busy error.

hi there,

just to remind that interface names are case sensitive...

are you using correct case?

cheers,

michael
