Depends on your provider really. Are they giving you mulitple IPs? If
so, OK. If not, bad idea since only one box will have a routable IP,
and your internal network will be exposed to the net. This may even be
a violation of the provider's use policy.
What you probably want to do is put 2 NICs in the gateway box. Run
ipchains and ipmasquerading from there. NIC 1 goes to WAN, NIC 2 goes
to hub. Other LAN boxes, use NIC 2's IP as their gateway. This works
quite well.

eth0 (or maybe eth1 if you go the 2 NIC route above).
