A second technique is to use the PPPtoDHCP Spoofing feature of
the
AST570
. The network configuration is practically identical to
the one described above:
Step
Action
1
Install two Ethernet PCNICs in a PC.
2
Install an OS on this PC that has routing capabilities, e.g. Windows
NT, UNIX, etc.
3
Install on this PC a NAT/PAT package that supports all TCP/IP
protocols.
Now this PC can act as some
'home gateway'
.
4
Connect (one of) the Ethernet port(s) of the
AST570
to the PC's
Ethernet PCNIC port.
5
Connect your local (W)LAN to the other Ethernet PCNIC.
6
Configure the PC (acting as
'home gateway'
) as DHCP client.
7
Configure the
AST570
as DHCP server.
8
DHCP in the
AST570
must be configured for DHCP Spoofing. See
subsection 14.4.2 for more information.
9
At least one PPP connection must begin with the mnemonic "DHCP"
in its phonebook name, e.g. DHCP_Spoof.
As soon as a DHCP request from the home gateway hits
the
AST570
, a PPPtoDHCP Spoofing connection is triggered.
The IP parameters that are negotiated with the remote peer are
carried up to the home gateway via a DHCP reply message.
