1. My error msg:

"Options warning: Bad backslash ('\') usage in server.ovpn:1: remember that backslashes are treated as shell-escapes and if you need to pass backslash characters as part of a Windows filename, you should use double backslashes such as "c:\\openvpn\\static.key"
Use --help for more information."

note: I've tried a number of combinations with how to reference the key files including replacing the \\ with \ or / , besides uncommenting the # where there is no use of referencing a folder, just to see. Config files I've seen that were posted to work for someone referenced files similarly as my config file. I even also tried commentiing out lines that reference log files with ;, jik, and still I get the same error stated in quotes above.

3. My procedure & what I did.

-When I installed the v2.1 rc16, I right clicked & ran as adimistrator, jik.

in command prompt I ran

-init-config...

-edited vars.bat default parameters as mentioned in the how to + changed

%programfiles% to %programfiles(x86)%

**vista x64 doesn't install openvpn in its regular program files folder... instead its \program files (x86)\ ,,, the (x86) evironment variable does point to it.


-excecuted vars, clean-all, build-ca, build-key-server server, build-key client1, build-dh & openvpn --genkey --secret ta.key
{ for keys I defaulted all values except common name & committed twice /w y where needed}

-I renamed the tap-win32 adapter v9 to "tap-bridge"

{My main ethernet which I bridged to tap-bridge gets its ip automatically from my d-link router's dhcp. That d-link dhcp is set to give 192.168.0.103 & is associated with its mac. I made sure the newly created bridge had both tap-bridge & local area connection checked in properties.

once bridged. I couldn't ping 192.168.0.103 and ipcondig would show my ip address got assigned to something else in the d-link's dhcp range, within 1 minute vista recognized the change and would be able to access the internet again.}

-I forwarded my udp port.

you mentioned that you changed %programfiles% to %programfiles(x86)% .
open a cmd prompt and type echo %programfiles(x86)% to be sure it is what you expect.

I believe you want this:
-dev tap
-dev-type tap
-dev-node tap-bridge
assuming openvpn --show-adapters shows it as being named tap-bridge

Why are you using bridge mode?
"**You ONLY want to use dev tap if you are tunneling layer2 traffic, if you are using IP traffic you want tun. If you are using tap only for windows file sharing, look into running a WINS server instead."
