A second technique is to use the PPPĆtoĆDHCP Spoofing feature of
the STWireless . The network configuration is practically identical
to the one described above, for wired LANs applicable only:
Step Action
1 Install two Ethernet PCĆNICs in a PC.
2 Install an OS on this PC that has routing capabilities, e.g. Windows
NT, UNIX, Linux, 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 interface(s) of the STWireless to the
PC's Ethernet PCĆNIC port.
5 Connect your local LAN to the other Ethernet PCĆNIC.
6 Configure the PC (acting as 'home gateway' ) as DHCP client.
7 Configure the STWireless as DHCP server.
8 DHCP in the STWireless must be configured for DHCP Spoofing.
See subsection 11.3.4 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 STWireless , a PPPĆtoĆDHCP 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.
