Networking help!!

Hi

I am looking to create 2 networks with 1 internet connection! And be able to manage the bandwidth between the two.

Is this possible/advisable?

I am thinking of possible set up


Modem
I
Network switch
I ................I
Router A Router B

Any pitfalls i should look out for?

Any suggestions for a Network switch with bandwidth management?

All advice welcome!

Thanks

the modem will probably be a router (i.e. a modem and a switch). so you shouldn't need two routers at points A and B.. depending on what you intend to do, one switch should do all you need.

If you want to perform traffic management then you will need something like a Linux box with two NICs. I don't think there are consumer-grade (i.e. inexpensive) switches that can do that. It's cheap enough in Linux anyway. You don't even need a machine with a hard drive.. just boot the distro from CD..

With a Linux box, you set up one NIC and expose it to the WAN (via the router) and the other NIC is exposed to the LAN.

Through the use of an iptables/netfilter ruleset, the Linux machine performs "IP masquerading" and filters/shapes the LAN traffic that can pass through the masquerading gateway based on IP address, destination port, etc..

There are off-the-shelf Linux distributions that handle all of that.. Smoothwall perhaps with tc (traffic controller) could do it all.

ok sound complicated.

The reason for 2 networks is to try to limit DS and DD using all bandwidth. P2P, xbox, ipods, youtube phones etc leaving none for me!

Modem is cable so not a router, so a lan swicth wouldn't split bandwidth in half, is there anything that does relatively cheaply? noted linux box acting as switch but not sure i am capable to do that!

No need for a seperate Linux box, just put two NIC's in your current machine and away you go.
