A bit tricky but what about this:
a) if several workstations share on ip you need masquerading and a linux
box to do it, assuming that "router" was a DSL<->eth "bridge/router" who
cannot do anything further.
b) you only have one HUB so lets plug everything in it (warning:
insecure!) We need two logical IP nets on this ethernet
DSL ------- HUB -------WORKSTATIONS
10.0.2.254 | 10.0.1.[1-253]
Linux
*10.0.2.2 *10.0.1.254
*10.0.2.1
c) configuration:
* all workstations send their packages to the default gateway 10.0.1.254.
* This (the linux box) masquerades as 10.0.2.2.
* The linux box itself has all services like web-server etc bound on
10.0.2.1. Since .1 is the eth0 and not the aliased eth0:0 interface
outgoing packets from the linux box should use this IP. (Do they?)
* Every packet from the linux box goes to 10.0.2.254.
