[Openvpn-users] problems only on windows server, while Linux is OK

Hi all!
 
-- config files are under the line.
-- short question is above the line down below.
 
 
I'm using openvpn on Linux (debian sarge) for a while, Linux is the server and
the clients are windows notebooks. Everything is just fine and there was really nothing
to do abotu configuration but follow the manual which was clear and great!
 
Last week I had to set up another VPN server on a windows 2003 box.
Everything started just fine and even my ***test client from a windows notebook
could connect***, but after the connection there is no traffic, ping, etc.
 
In "Remote access and Rounting" under Win.serv.2003 I allowed ALL traffic from
any address on the interface (TAP), but it is not working.
Connects, but nothing else.
 
It seems there should be a ROUTING problem, but I'm a *poor and looser* application developer,
not a TCP/IP guru, so I just cannot see what the problem is - I'm not really into IP routing.
 
The Linux and Windows routing table seems so much different that I cannot identify what the
difference is (I made the two openvpn network absolutely identical for all settings).
 
 
Q: What the carrot*?
 
/* = Hungarian, meaning "what the ....?"
 
 
Thanks
 
Robert
