It would be too lengthy to explain in detail the router´s configuration of the VPN settings concerning
the internet. There are different procedures depending on the manufacturer, although the standar-
dized adjustment possibilities are always the same.
Details can be found in the manuals of the VPN routers.
Depending on the features these VPN routers can use fixed/static as well as dynamic, meaning
varying, IP addresses of the DSL provider.
IMPORTANT:
When choosing a router, please make sure that the router is VPN suitable. As menti-
oned before it is favorable to use similar devices by the same manufacturer.
Connection via ISDN
At locations which have a telephone line (ISDN), but no DSL access, an ISDN router can be used.
In this case the remote side can be contacted via an ISDN connection. The DSL routers in the
above mentioned example can be replaced by ISDN routers. These build up a dial-up ISDN con-
nection to each other.
A FT636 network interface needs a bandwidth of at least 96kBit/sec, channel bundling is necessa-
ry. This means that both channels of an ISDN connection have to be available for the FT636 at the
same time and at full bandwidth for a single connection.
