Useful Information on Internet Access Configuration Examples
■
PPTP : The Point-to-Point Tunneling Protocol provides a VPN setup which is easy to configure. You provide
on both sides a password for the mutual authentication and encryption.
■
IPSEC : For higher security demands, you should use this protocol to secure the VPN connection. You
should transfer the keys to be entered on the configuration page via a secured channel (e.g. as disk file or
via postal service).
■
ISDN : If an IP data transfer is required to the other LAN, the Comfort Pro S initiates a dial-in via ISDN.
Note that such a connection is only set up when specific requests are made. These can be for FTP file
transfers, e-mails or downloading Web pages. Name resolution via broadcasts is not possible. If you wish to
use the LAN-to-LAN link to access files and printers in the Windows network, you need an IP-enabled server
that administers the name resolution for the Windows network.
As the IP address range, you can select one of the 256 class C subnetworks designed for local LANs. Select a
class C sub-network in the range from 192.168.0.0 to 192.168.255.0.
Useful Information on Internet Access
Costs
The Comfort Pro S uses a router function to access the Internet, which means that it automatically establishes
an Internet connection when required and terminates the connection after a certain period of time if no data
are being transmitted.
Unfortunately, programmes other than those typically intended to access the Internet (such as your browser
or your e-mail software) may send out data packets which cause an Internet connection to be established,
even if these programmes are not strictly Internet-associated applications.
Examples of such programmes are the Microsoft
TM
XP
TM
operating system, various multimedia programmes
such as Realplayer
TM
and anti-virus applications that may establish an Internet connection for automatic
updates (the so-called “phone home function”).
It is therefore highly advisable to limit ISP access by specifying the maximum monthly connection time under
Connection time per month in the Network : WAN : [Provider] menu on the web console.
