Accept incoming PPTP connections
When enabled, the router acts as a PPTP server and accepts incoming VPN connections.
Enable Server mode
When enabled, the router sends call_out call requests to the remote device. In the default
state which is unchecked, the router sends a call_in request to the remote device.
Enable Socket mode
When enabled, enables the use of a Digi proprietary mode whereby PPP packets are sent via
the PPTP control socket rather than in GRE packets.
Encrypt control data using SSL version n
When enabled, the router encrypts the control data using SSL. This is a Digi proprietary function
and is not part of standard PPTP. The drop-down list allows the SSL version to be selected. The
available options are:
n Use default
n TLSv1 only
n SSLv2 only
Enable PPTP debug
Enables debug tracing.
