When things are not working as desired it is always a good idea to have a look into the system log. In the GUI you will find it under System > Troubleshooting > System Debugging > Log Viewer. In the console, just type tail-log which is a shortcut for tail -f /var/log messages
tail-log
Other things to look at:
root@192.168.1.1: ifconfig (what are the interfaces doing? Is there an IP assigned to the relevant interface (wwan0, wlan0, lan0, tun0, etc.)
root@192.168.1.1: ping 8.8.8.8 (do we have Internet access?)
root@192.168.1.1: cat /etc/resolv.conf (do we have DNS servers? Which ones?)
root@192.168.1.1: route -n (what about the routes? Is there a default route? Is there a route to the OpenVPN sever?)
root@192.168.1.1: tcpdump -i wwan0 -n (are the packets travelling as expected?)
