View Full Version : [ubuntu] Help with Network Topology and Firewall

February 4th, 2009, 09:56 PM
I would like to install an Ubuntu firewall on our network but I'm confused about some things because I'm not very familiar with how networks function. Please see the diagram I attached.

I would like the printers, servers, and workstations (desktops and laptops) to be placed on 3 different subnets.

Should I allow the firewall to also act as the DHCP server and serve the 3 different subnets???

Will it be possible with the proper iptables configuration to allow Desktop 3, for example, to communicate with Server 3 (the file server) or with one of the printers??

I would suggest you start here (http:///tldp.org/HOWTO/NET3-4-HOWTO.html), then have a look at this iptables howto (http://help.ubuntu.com/community/IptablesHowTo).
