hey brian,

I openend those ports on the server-side, but no help. i researched some further and
found those rules for iptables, i think my client needs them

 Allow TUN interface connections to OpenVPN server
iptables -A INPUT -i tun+ -j ACCEPT

# Allow TUN interface connections to be forwarded through other interfaces
iptables -A FORWARD -i tun+ -j ACCEPT

...all i can explain, why ssh is working through vpn is, that ssh is opened on client
AND servermachine...

Gonna try results and post. If this is the reason, i think i will then file to bugzilla,
as those rules should be inserted in Network-Manager, thats where i manage the
openvpn-connections.

Thanks,
Roger
