Functions MoRoS GPRS 2.1 PRO
12.6.7 Setting Up a PPTP Client
The settings for the MoRoS GPRS 2.1 PRO as PPTP client are configured here. All
packets through the PPTP tunnel are masked by the MoRoS GPRS 2.1 PRO with its
tunnel address.
Configuration via the web interface
In order to use the MoRoS GPRS 2.1 PRO as PPTP client, check in the
menu "Dial-In", "Dial-Out", or "LAN (ext)" on the page "PPTP client" the
checkbox "Activate PPTP client".
In order to display the messages of the last connection, select the link
"Display log of last connection".
In order to define the IP address or the domain name of the remote termi-
nal, which you use to have the MoRoS GPRS 2.1 PRO establish the VPN
connection, enter an IP address or a domain name in the field "IP address
or domain name of remote site".
Enter the user name and the password of the PPTP client for login to the
server into the respective fields.
In order to select the encryption for the PPTP connection, select this from
the drop-down list "Encryption". The encryption that is also used by the
PPTP server must be selected.
In order to set the default route to this PPTP tunnel, check the checkbox
"Set default route". The complete data traffic will be routed through the
tunnel then. However, this is only possible, if no preferential default route
has been set before.
If no default route to the tunnel is set, the local subnet behind the tunnel
must be defined. Enter this network with respective netmask into the field
"Remote subnet". Only that way, packets into the network behind the
PPTP tunnel will be routed through the tunnel.
In order to adjust the MTU (maximum permissible number of bytes in a
packet to be received), change the entry in the entry field "MTU (Maxi-
mum Transmission Unit)".
In order to adjust the MRU (maximum permissible number of bytes in a
packet to be sent), change the entry in the entry field "MRU (Maximum
Receive Unit)".

The default settings of MTU and MRU are suitable for most applications
and do not need to be modified usually.
In order to configure a connection check using a ping via ICMP protocol
to a domain or an IP address, enter this into the entry field "Additional
ICMP ping to". It is recommended to enter a domain name or IP address,
which can only be connected via the tunnel, here. If the connection check
is not successful, a possibly existing tunnel will be terminated, and a new
tunnel will be established. The ping interval is 15 minutes.
