VPN
The router can be used as a VPN (Virtual Private Network) client. VPN is widely used for
connecting to corporate networks from a remote location. The credentials must be given to you by
the administrator of the virtual private network.
Note: If your Internet connection should run into any disconnects or strange behavior when using
session intensive protocols (such as BitTorrent) during use of an encrypted PPTP tunnel, then
please make sure to enforce a low speed cap on the relevant application. Real-time (MPPE)
encryption/decryption is a CPU-intensive task for the router and offers limited bandwidth
throughput.

PPTP
For setting up a VPN with PPTP you need to provide the server's IP-address or hostname, along
with login credentials. This should have been provided to you by the system administrator or your
VPN service provider. It is sometimes optional to use encryption, referred to as MPPE. The usage
of encryption will result in lower throughput as well as higher transmission latency (ping), since
each data packet must be encrypted/decrypted.
To enable PPTP select the tick box and enter the VPN Server profile
To create a new VPN Server, click on the drop-down and select Create New Profile and fill out the
following settings
Profile Name here you enter the name of the profile eg. MyVPN-Service
Server Enter the host-name / IP address to which you want to connect
Username The VPN account username with which you want to connect, if you don't know it
please contact your IT administration or your VPN provider
Password The VPN account password with which you want to connect, if you don't know it
please contact your IT administration or your VPN provider
Echo timeout The PPP echo timeout value, this value is normally 60 seconds
Echo count The PPP echo counter value, this value is normally 3 seconds
MPPE (encryption) Select if the connection should use encryption or not. Encryption can
have impact on the throughput and latency. By default, encryption is Enabled
Default profile Click here if you want that the router automatic should connect with this
profile
If VPN goes down Here you select what the router should allow to happen if the VPN disconnects.
Either you let the hosts continue to surf on the Internet directly (without VPN), or you decide to
block them from accessing the Internet.
Advanced Settings
Number of retries Here you can choose how many attempts the router should try to connect
to the VPN. You can also select that it will continue to do unlimited retries. If the router can't
connect within the limit, a manual connect or a reboot of the router will be required
Routing of internal services Here you can select how the router's own traffic should be
routed to the Internet; either via the Direct connected interface or the PPTP/VPN tunnel. All
traffic that originates from the router such as DNS-lookups, NTP, Live Update checks, etc
shall use this interface
Forced VPN Here you can designate which hosts on your network should use the VPN
connection. By default, all hosts on the network will use the VPN connection. If you only wish
