I am connecting three seperate networks together to share the internet. I have a DSL line that I am goig to put a Linksys DSL router on. I do not want the computers on the seperate networks to see one antother. I just want them to share the internet connection. Questions 1. Is this hard to do? 2. Would they see each other through the router? 3. If so how can I stop them from seeing each other? 4. Some of the networked computers share IP addresses (they were all seperate networks before. Can I leave the IP addresses or do I have to give them all unique IP? 5. The router can act as a DHCP server should I let it assign IP or can I assign them manually? 6. Since they are on three seperate networks would this be hard to setup or even possible? 7. Is there a benefit to either way? Sorry for the amount of questions.

1.) nothing is hard, if you know the answer. 2.) I am not sure what you mean 3.) You can use a firewall to blocke them from seeing anything 4.) All three network or(Subnets) would maybe change 5.)either or 6.) YEP, it can be done 7.) I would need to see the lay out.
