QNX as an inernet router..?

I’ve downloaded and instaled the QNX ISO CD (about 90Megs) and I’m prety
happy to see an OS like this.

I’m using now a PC with Winroute as internet router, but I’d like to convert
this PC to QNX.

Is there any free software for QNX that makes the job of winroute, or at
least NAT?

I’ve downloaded a Samba port for QNX but it askes for the full TCP/IP
package, wich I also downloaded, but can´t install it…
