I've installed a TP-R470T+ and configured it with the necessary ports for a VPN (PPTP) connection. It works well but, if client-side I don't use the connection for several minutes (about 30, seem to me), I find it blocked (but not closed) and need to disconnect and reconnect. If I work on the connection, it remains active and functional. This behavior does not happen with the old firewall.
Is there some time-out parameter to set? I only found something similar in the PPPoE parameters, but is not my case (I'm connected to the WAN with a modem/router via static IP).

Thank's
