hello, Firstly sorry for my english 🙂
I am trying to build my own router based on raspberry PI2 (raspian OS).
Computer -> WIFI -> raspberry PI -> USB modem 3G/LTE -> VPN -> Internet
I don't have problem with WIFI connection to rasberry, and no problem with internet connection (USB modem - huawei).
I have problem with OpenVPN (i think it Can be connected with routing). When i connect with usb modem there is internet but if i after connect with openvpn (Private Internet Access) i don't have internet.
Here few logs:
After connect with wvdial:
root@routerlte:/etc/openvpn# ping google.com
