A similar configuration as above can be used in combination with
the PPP to PPTP Relay.
Instead of installing an ATMF 25 PC NIC, you must install a
second Ethernet PC NIC that connects to the
By setting up a PPTP tunnel from the 'home gateway', again the
Public IP address is transported transparently through the
to end up in the 'home gateway'.
A third technique is to use the PPP to DHCP Spoofing feature of
the . The network configuration is practically identical to the
one described above:
Step Action
1 Install two Ethernet PC NICs in a PC/workstation.
2 Install an OS on this PC/workstation that has routing capabilities,
e.g. Windows NT, UNIX, etc.
3 Install on this PC/workstation a NAT/PAT package that supports all
TCP/IP protocols.
Now this PC/workstation can act as some 'home gateway'.
4 Connect (one of) the Ethernet interface(s) of the
PC/workstation's Ethernet PC NIC port.
5 Connect your local LAN to the other Ethernet PC NIC.
6 Configure the PC/workstation (acting as 'home gateway') as DHCP
client.
7 Configure the
8 DHCP in the
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 , a PPP/DHCP 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.
