OK, once you've got the linux box able to ping something on the other side
of the road the rest is just general network issues (and security issues
as Simon pointed out). You're probably going to plan for a subnet to be
allocated for the side of the road the 6 windows users are on. This will
simplify routing and everybody's happy.
If you have 192.168.1.0 on the server's side perhaps pick 192.168.2.0 for
the side accross the road. Then on the server's side you'll need to add a
route to 192.168.2.0 and on the linux box set your default route back to
the server (or whatever your real router is).
[ws] 192.168.1.21
|
192.168.1.254 | 192.168.1.2
internet--[router & firewall]--[hub]----[server]
(need not exist) |
[access point] (passive device?)
|
[wireless] 192.168.1.5 eth1
[linux] 192.168.2.1 eth0
|
[ws]-----[hub]----[ws]
192.168.2.21 192.168.2.22
On the linux box you'll also need to enable routing
echo 1 >/proc/sys/net/ipv4/ip_forward
is one way.
Now some router that the server can see must be told to route packets for
the 192.168.2.0 network. Whether that be your internet router, some other
router or the server itself depends on the network hierachy present.
