Trouble in internet sharing

[sanric]

Hi everybody,

as far as I've got a pretty nasty Nas4Free server, I'd like to use it in order to make video conversion via FFMpeg but I am not able to connect to the internet.
Here' s the configuration:

MacPro with 2 ethernet ports:
-> port 1 with static id and connected to a router
--> ip: 192.168.1.1
--> mask: 255.255.255.0
--> router: 192.168.1.254

-> port 2 with static id connected to the nas
--> ip: 192.168.0.1
--> mask: 255.255.0.0

Nas4Free server with 1 port
-> port 1 with static id and connected to the MacPro
--> ip: 192.168.0.2
--> mask: 255.255.0.0
--> router: ?!?

I've tried turning on Internet sharing on the MacPro with no results.
Here's the question: how have I to configure the machines in order to make the NAS connect to the internet?
Thanks to all for the kind replies.

why not connect the NAS directly to the router too?
don't know how to enable internet sharing on a mac, only Windows PC.
with "router" you mean "Default Gateway", so you'll have to add you Mac's Port2 IP to the NAS Default Gateway ("router")

why not connect the NAS directly to the router too?

Quite simple: I have all the router ports filled, no one left!
Moreover the router is 10/100 whilst the Macpro-Nas link is Gigabit with a cat6 cable: the difference in terms of transfer rate is astounding.

my advice would be: buy another gigabit switch not really expensive
