Hi everyone, The following is my current task. 1) set up a network with 6 computers 2) must have file and printer sharing 3) internet access Things to consider 1) SECURITY - some computers will be laptops (wireless) and some desktop (hardwired) 2) Connectivity - at least one of these computer will be a mac laptop - about 50% windows xp and about 30% vista My Questions: 1) How can i separate my LAN from the internet? 2) Can i share my same LAN via hardwire and/or wireless? - if so how would i secure my LAN network from the internet? **Setting up the network is not the challenge, adding security given the variables is what makes it somewhat difficult for me to breakdown. Any advise, suggestions or ideas will be greatly appreciated. Thank you!

Thanks. We'll let you know when a new response is added.

I would suggest going to your local computer store (Bestbuy, compusa, etc) and buying a hardware firewall. Dlink, Linksys, and others make some that generally include a 10/100/1000 switch (for the hardware/wired network) and a wireleass access point (for the wireless).

This should get you a long way toward your solution you’ve requested and accomplishing all of the things you’ve asked.

**********
A wireless router and possibly a switch should handle the hardware side depending on how many wired clients.
For file and print sharing, check <a href=”http://downloads.techrepublic.com.com/download.aspx?&q=connect+microsoft+windows+systems&docid=254383″>here</a> for allowing windows to connect to your mac and <a href=”http://downloads.techrepublic.com.com/download.aspx?&q=Macintosh+OS+x+systems+to+windows+networks&docid=264548″>here</a> for connecting mac to your windows network. let the router and individual machine firewalls and AV control the security. Some higher end routers have excellent firewall capabilities.

    the hardware firewall will block you from the internet and is a good idea but it will not help if someone does get in, (logging), and it will not get him file and print services. what you can do is get a system that has enough disk space to hold what you want to save for all your users then setup a server on that. if you don't have the money to buy something like windows server 2003 then lookup Mitel's SME server. This will give you a free OS that has file and print services, good security, email server, web server, ftp and other services. It also has a very good support base if you need support. You will need to learn linux but it is very easy to get up and running and easy to use. If you want even more security you can install IPCop Firewall on an old used computer that is an excellent firewall that will log all access coming in and going out and also has a separate section you can setup for wireless access.
