Ok, i've got a hard one for you guys, that's why i'm awarding 500 points.
This is my situation,
I have a linux box (redhat 9.0) with ETH1 connected directly to a Wifi hotspot, thru that hotspot i want 3 users to connect to the interanet (a exchange server) and all the others that connect to the hotspot directly to the internet WITHOUT them seeing the local network.
The setup now is like this,
Internet -> Windows 2000 server SBS -> localnet (192.168.1.0) -> Linux machine (192.168.1.6) -> Wifi Hotspot
I have allready setup a PPTPD on the Linux box, and it's working like a charm..
The reason that i do NOT want the "internet" users to see the local network is because it's a company network, and i don't want somone to try to hack or something like it.
I am able to change anything i want, but i prefer to have the windows 2000 SBS connected directly to the internet.
Also the Linux box must have access to the internet thru the Windows 2000 box (at this moment that is working fine thru eth0) for the mailserver.
So who can help me with this one?
Here's a bit more background info
Win2k SBS 192.168.1.5 <-- this can NOT be changed
Wifi hotspot 192.168.1.1 <-- this can be changed
Linux box ETH1 192.168.254.254 <-- this can be changed
Linux box ETH0 192.168.1.6 <-- this can be changed
