I have been given a task to setup One to One NAT on a Linux box. If I'm correct I need to do this iptables -t nat -A PREROUTING -p tcp -d 192.168.1.1-j DNAT --to-destination 172.100.1.1 First off, is this the correct syntax? If not, I can't find for sure what I would have to do. Any suggestions? Second, here is another scenario I have to do. I work for Tech Support, and we have a lab full of devices to assist us when working with Customers. Our internal IP Scheme is 192.168.0.0/16. Some of the devices are 192.168.1.0/24 and can't be changed. The original plan was to setup a 1:1 NAT with the Linux box to forward to the /24 network so we could use all of the devices, but since I have been given the project I can't see it working. How will the Linux box know which network to pass information on to since they are both 192.168.x.x. Any suggestions or ideas? Thanks in advance, Eric
