In my opinion the "Debug OpenVPN-Settings-ip-route-stderr 2402  Permission 
denied" message is for the "ip ru del table gprs"
command. And that is correct. If I execute "ip ru del table gprs" in a terminal 
the VPN works correct...

I want to use this command in my config with "up 'ip ru del table gprs'", but 
when the gprs route does not exist (for e.g. I execute this command before) 
then I get the return value "1" (error code) and OpenVPN will close the VPN.
So I have to execute the command everytime manual in a terminal.

I have a Desire HD with the same config and the logcat don't show this error. 
The OpenVPN-, BusyBox- and iptables Version is exact the same (same MD5 hash).

Maybe someone could help me with that.
Evertime I want to execute a script in the OpenVPN config (e.g. "up 
/etc/script.sh"), I get an error that the external program could not be 
executed. The permissions are correct, it is read- and executable.
Or the VPN Settings App get updated for the Flyer :P

Many regards :)

Hello folks,

I've found a Solution for the Flyer Users, who use OpenVPN.

I hope the developer won't rip down my head, for scamping in his app...
I've disassebled his app and search for the part which controls the "Fix HTC 
Route" option.
I've found in 
"de.schaeuffelhut.android.openvpn-1.apk\smali\de\schaeuffelhut\android\openvpn\s
ervice" a file called "ManagementThread.smali".
Between line 2823 and 2863 you can find a "function" called ".method protected 
updateHTCRoutes()V".

There are the commands "ip ru del table wifi" and "ip ru del table gprs".
I've changed "ip ru del table wifi" to "ip route flush table 2" and reassemble 
it, uninstall the old OpenVPN-Setting and replace it with the new assebled one.
And now all is working, but after the "ip ru del table gprs" sometimes I get an 
error in the log (only if the gprs entry not exist when you execute "ip ru") , 
but that don't affect the function of the script.
But now the fix route option does not work for the WiFi users. But I don't have 
tested it yet...

I am only a little script kiddie who knows a little bit about "AutoIt", but as 
soon as I found out how this function really works, I try to find a more clean 
way to solve this issue.

Many regards :)
Chris

But now it does :P
As I say, maybe I will try to fix it for the Flyer and then I will post it here.
And of the developer don't agree with this, he can send me a mail (if he is 
still alive :P)

Many regards
Chris :)
