The STPro offers some solutions to cope with this situation.
Basically these solutions boil down in transporting Public IP
addresses transparently through the STPro towards a device
where a more advanced NAT and/or PAT can be performed.
Some solutions are described in the following paragraphs:
ATMF25.6 (if equipped)
Via the PPPtoPPTP Relay
PPPtoDHCP Spoofing.
The ATMF25.6 port offers maximum TCP/IP transparency
because it switches ATM cells and does not touch TCP/IP
information.
You might consider the following setup:
Step Action
1 Install both an ATMF25.6 PCNIC and Ethernet PCNIC 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 'h
ome gateway '.
4 Connect the ATMF25.6 port of the STPro to the ATMF25.6 PCNIC.
5 Connect your local LAN to the Ethernet PCNIC.
The Public IP address goes transparently through the STPro to
end up in this advanced 'h ome gateway ', where more complex
NAT and/or PAT operations can be performed.
