Hi, I am having an issue with this. The openvpn client i tested it on a linux box with site 2 site and there it works. So i ruled out any issue on the server side. It seems to be in the teltonika box it self.. I cannot ping the openvpn server ip from the lan; but i can ping the teltonika openvpn ip on the tunnel. When i SSH in the teltonika i can ping the openvpn server ip and the teltonika IP. It must be firewall related. I have checked all that there are no blocking rules or what so ever. All is on pass and allow but the device is still not letting the packages over the vpn originating from the LAN on the teltonika site.
