You state that you have a router, is it a multi-port router? That could interconnect your other devices. You'll keep your server's CPU free to do other things. -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/

I'd keep it how you've got it at the moment. It might not be such a good idea to run a firewall on the same box as a server. What sort of media are you storing? You should be able to support up to high definition video on a 10/100Mbit connection. I have 8 machines connected to my server for media sharing, over a 100Mbit connection and it runs fine. My server is even running VMWare too so it's technically split into two machines. If you did decide to go ahead though, you'd need crossover cables to go from the PC to the NIC on the server, plus you're limited on how many slots you have. If you're worried about bandwidth maybe you should invest in a gigabit switch and gigabit NICs.

As far as I know, there are two ways of achieving this. You can either configure each card on a separate subnet and set your box up to forward packets between them, or you can create a bridge device containing each ethX device you want to bridge, and they will be configured as one device. The latter is probably what you're after, I have done this before to bridge my VirtualBox VMs with the rest of my lan and it works quite well. Will I need patch or crossover cables. Whether to use a straight or crossed cable depends on the device you're using rather than the configuration. PC to PC, or hub to hub uplink demands a crossed cable, most other applications use straight cables (eg. PC to hub, hub to hub non-uplink).

Each NIC would need its own IP address; I'm not aware that you can assign the same IP address to multiple NICs without a great deal of hassle. It's relatively easy to share the modem across multiple NICs with different IP addresses, but the final devices would not be able to talk to other devices without setting up routing, which is reasonably advanced. For example: Modem -> PC -> Laptop1 -> Laptop2 ...would prevent Laptop1 talking to Laptop2 unless you set up routing. Given that you can buy a brand new network switch for less than five pounds: http://www.google.co.uk/products?q=network+switch&scoring=p ...this is an extremely complicated way of achieving a very simple result. Instead I recommend: Modem -> PC -> FiveQuidSwitch -> Laptop1 -> Laptop2 -> Printer -> etc. If by "modem" you mean "Broadband modem with Cat5" rather than "USB modem" or "pre-broadband modem", then you can achieve even better results with: Modem -> FiveQuidSwitch -> PC -> Laptop1 -> Laptop2 -> Printer -> etc. -- Andrew Oakley -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/

That would work well, we have a similar system that basically firewalls a router, with a web based interface that lets me change settings. If you have pci wireless cards you can use ubuntu as a wireless AP. Additionally, as you can firewall the interfaces on the machine you could also use it as a hub. By installing Samba you are able to share the files over the network. I couldn't personally tell you how to configure the interfaces for sharing the internet connection, or the firewall configuration, but it is possible. -- Kris Douglas Softdel Limited Hosting Services Web: www.softdel.net Mail: [EMAIL PROTECTED] -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/
