A similar configuration as above can be used in combination with
the STPro PPPoAtoPPTP Relay.
Instead of installing an ATMF25.6 PCNIC, you must install a
second Ethernet PCNIC that connects to the STPro .
By setting up a PPTP tunnel from the 'home gateway' , again the
Public IP address is transported transparently through the STPro to
end up in the 'home gateway' .
A third technique is to use the PPPtoDHCP Spoofing feature of
the STPro . 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, 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 STPro to the PC's
Ethernet PCNIC port.
5 Connect your local LAN to the other Ethernet PCNIC.
6 Configure the PC (acting as 'home gateway' ) as DHCP client.
7 Configure the STPro as DHCP server.
8 DHCP in the STPro must be configured for DHCP Spoofing. See
section 12.4 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 STPro , 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.
