It's been answered properly here a number of times. You were to busy
complaining about your not understanding the answer to notice that.
The simple solution is:

1) Get an IP address from your ISP for the second machine. Configure
	the machine to use that address.

2) Enable GATEWAY (apparently a kernel recompile) on the machine with
	SLIP on it.

That's really all there is to it.

The problem with the simple solution could well be step 1). If your
ISP refuses to give you the IP address, then it's no longer a "simple"
question. You now have to arrange to have the gateway machine put its
IP address on packets from the interior machines before sending them
out, and figure out which incoming packets belong to it and which
belong to interior machines, and distribute them appropriately.
Documentation on how to do that is what Cees De Groot was pointing you
towards.

I haven't looked into doing this operation. However, gettting a class
C network from the NIC is simple, asking your ISP to route to that
network is simple, and finding another ISP if they refuse to do so is
also simple. Which is why that's the route I would take.
