The gateway to access the outside world can be a dedicated PC as
shown in subsection 4.5.1.
However, the
STWireless itself is designed to act as a cost
effective ADSL gateway.
STWireless ADSL Router
acting as Home Gateway:
Ć Routing
Ć NAPT
Ć Firewalling
Ć Name Resolving
ADSL Line
Ć DHCP
To perform the gateway tasks itself, the STWireless has, in
addition to the ADSL modem part:
"
An IP router (See section 11.4)
"
A DHCP server (See subsection 11.1.4)
"
NAPTabilities (See subsection 8.4.6)
"
A DNS server for local name resolving and DNS proxying
(See chapter 12)

A Firewall (See chapter 13)
MER, PPP & IP Routing and CIP & IP Routing are ideally suited for
the ADSL gateway model.
