set Provider 4711000 * * PPPHDLC OFF
햴
The user name and password to be sent when the remote station is dialed up are
stored in the PPP list. The PPP negotiation has 'no' security from this end because
only the ISP requests your name and password, but you do not request these from
the ISP.
cd Setup/WAN-module/PPP-list/Default
set Provider no surfing * * WEB_USER IP
The password 'surfing' will be replaced by several asterisks (*) when entered. The other
asterisks (*) in this entry stand for the values which are to be used without alteration.
Please note that user name and password are case-sensitive.

Now all that is needed is to clarify the addresses. To enable the router router in its
own TCP/IP network to be found, it needs a free IP address from the Intranet. It
receives this as part of the entry for the Intranet address together with the
associated netmask (configuration area 'TCP/IP', 'General' tab).
cd Setup/TCP-IP-module
set Intranet IP address 10.100.100.50
set Intranet netmask 255.255.255.0
set operating on
The entries for the IP address and the IP netmask are empty because in this example the
router obtains the IP address dynamically from the ISP. If, on the other hand, there are
IP addresses available which are registered and are valid on the Internet, you would enter
one of these here together with the associated netmask (see also 'Intranet with its own
Web server on the Internet').

The settings thus far have practically integrated the router into the Internet, but the
computers on the LAN are not yet able to surf. To achieve this you must create an
entry in the routing table (configuration area 'TCP/IP', 'Routing' tab) so that any
packet destined for addresses which cannot be reached locally is routed into the
Internet (DEFAULT route).
cd Setup/IP-router-module
set IP-routing-table 255.255.255.255 0.0.0.0 Provider
2 ON
The route to the IP address '255.255.255.255' with the netmask '0.0.0.0' intercepts
all packets which cannot be assigned locally. 'Router' identifies the remote station
to which the relevant data is to be sent. The remote station can be accessed directly
from your router so the distance is set at '2'. Setting the option for IP masquerading
to 'ON' hides all the computers in the LAN behind the router's address so that they
will not appear on the Internet.
