Workaround (script) found here works just fine:
https://bugs.maemo.org/show_bug.cgi?id=7596#c9

- Copied the script to /etc/openvpn
- Added
Code:
script-security 2
ipchange /etc/openvpn/add_default_route.sh
to my openvpn config file and all traffic was tunneled (tested with Wireshark). BTW, there is one last thing I had to do in order to get DNS resolution, I had to add
Code:
nameserver 192.168.0.254
Where 192.168.0.254 is the address of my router at home to either /var/run/resolv.conf.gprs or /var/run/resolv.conf.wlan0 depending of the connection.

To automate that process I simply added the following to the workaround script found up there:
Code:
if [ -f /var/run/resolv.conf.gprs ];
then
  echo "nameserver 192.168.0.254" >> /var/run/resolv.conf.gprs
fi
if [ -f /var/run/resolv.conf.wlan0 ];
then
  echo "nameserver 192.168.0.254" >> /var/run/resolv.conf.wlan0
fi
As a side note here are the special options I have enabled in my openvpn config:
Code:
push "route 192.168.0.0 255.255.255.0"
push "redirect-gateway def1"
push "dhcp-option DNS 192.168.0.254"

I now have OpenVPN working on both Wifi and Gprs with full internet traffic routed through the tunnel... cool!
