Access to Remote CAPI

The special features offered by BinTec routers include implementation of the
Remote CAPI and for PABXs the Remote TAPI programming interfaces.
This enables applications on computers in the LAN to use the resources of the
router as if these components were installed directly in the computer.
By using BinTec's user concept, you can make sure that only users authenticat-
ed by user name and password can access X4100/200/300's Remote CAPI in-
terface (see figure 6-3, page
You can also prevent unauthorized access by defining filters (see
page 319) and local filters (see

NAT (Network Address Translation)

NAT is a simple-to-operate procedure that can be used for several pur-
poses in the BinTec implementation:
Hiding the internal host addresses of a LAN by remapping to one or more
external addresses.
Controlling external to internal access. In the external direction, the router
forwards all data packets
nal callers are only allowed if explicitly enabled.
