NAT with iptables

[Peter Bossley]

Slightly off topic but Bil suggested I post here:
Here's what I need to do: I want my redhat linux machine to forward all
packets from my network out my dynamically assigned IP address my cable
provider gives me:
local interface is eth0
cable interface is eth1


All I want is  a simple NAT setup: I dont need any filtering.  Can someone
send me the commands I need to use and where  I should put them (this would
be great so I can get rid of my router, which isn't worth a darn anyway)
