10.2.11 TAF Client
Personalized
authentication
The Token Authentication Firewall (TAF) function permits personal
authentication of IP connection partners. BinTec’s solution integrates the Token
Authentication mechanisms from Security Dynamics and does not allow data
packets to cross the router until the associated source address has been
authenticated successfully.
You can activate this function in X4000 (with extra license) and configure the
router as TAF Server or TAF Client. A detailed description of the operation and
the necessary configuration steps can be found in BRICKware for Windows .
10.2.12 Extended IP Routing (XIPR)
In addition to the normal routing table, X4000 can also make routing decisions
based on an additional table called the Extended Routing Table (Extended IP
Routing). Apart from the destination address, X4000 can also include the
protocol, source and destination port, type of service (TOS) and the status of
the destination interface in the decision. If there are entries in the Extended
Routing Table, these are treated preferentially compared with entries in the
normal routing table.
Example XIPR is useful, for example, if two networks are connected via ISDN with a LAN-
LAN connection, but certain services (e.g. telnet) should be routed over an X.25
link and not over an ISDN switched connection. By making entries in the
Extended Routing Table, you can allow part of the IP traffic to run over the ISDN
switched connection and part of the IP traffic (e.g. for telnet) to run over an X.25
link (see also the Software Reference ).
Configuration Configuration is made in the Setup Tool menu IP
