Operation Manual

KEN! Internet
KEN! – 5 KEN! for the Network Specialist 99
• The Internet access time control allows access to be de-
activated at certain times of day and facilitates auto-
matic time-controlled dialing of configured Internet pro-
viders.
• If required by the E-mail provider, Internet providers can
be assigned to E-mail providers.
• The configuration of a backup provider can ensure that
Internet access is possible at all times, even during
temporary outages of the active provider. The program
switches to the backup provider when dialing to or PPP
negotiation with the active provider fails repeatedly. Af-
ter one hour KEN! attempts to dial in to the active pro-
vider again. This function makes particular sense for
providers that are extremely economical, but not very
reliable.
• Packet filters for outgoing and incoming IP packets pro-
tect the KEN! Service PC from attacks and prevent the
system from connecting to the Internet unintentionally
through mechanisms specific to Windows, viruses or
advertising servers.
• The “AVM KEN PPP over ISDN” network adapter in the
Windows network settings is configured and controlled
by KEN! Internet.
The Network Adapter Driver “AVM KEN PPP over ISDN”
The network adapter with this name in the Windows Network
settings establishes the PPP over ISDN connection to the In-
ternet provider for the KEN! proxy and E-mail server without
the restrictions associated with Dial-Up Networking.
The network adapter driver (NDIS) for ISDN adapters (CAPI
2.0) offers the following functions and features:
• For reasons of security, only outgoing calls are permit-
ted; incoming calls are rejected.
