Hello 

Another issue that i checked is that when you reboot the c2700 when come back the DDNS does not start automatically !

You need to enter on the option and click on login and save to start working.

AFTER CLICK on LOGIN and save ....

Another problem related to this is the PPTP VPN Server.

 I have configured OPEN VPN and PPTP VPN Sever.

Using my android phone with Open VPN APP,  i can connect the vpn with no issues.

when configure a desktop using WIN 10 or LINUX Ubuntu to connect, everytime i got ERROR 619.

This is the configuration at PPTP VPN ...

I also tested with all checkboxes below selected but with no success...

Do you know if need to configure at C2700 something else to allow this VPN Connection to work properly ?

i also made a test trying to connect the PPTP VPN inside my WIFI network using the c2700 with a notebook and worked fine, but when try to do the same outside my network does not work.

Thanks,
