Yes, but this MUST be from DIFFERENT IP's originating the connection as
others have inidicated.

No you cannot use the SAME Ip for both.

Yeap. Also even if you have different IP's you'll have to deal with routing
issues.
This is why additional connections should ideally occur on different
subnets...
|He Has DSL and 2 NICs to share internet(Win98), typical setup...

|Is this a windows connection sharing thing? I want my friend to put a
|linux NAT/firewall in, but he had a rough experience with linux and a
|2940 SCSI controller, I think it was coincidence, but he spent so much
|time trying to fix it afterwards that I won't be able to talk him into
|linux for 6 months or so.
|
|I'm planning on updating everything soon, so I thought the problem might
|"fix itself", but I saw the topic and had to ask...
|
Eh do you really mean PPTP?
The above implies that what you are looking for is MASQ/IPCHAINS...
