Internet Access for Separate Network

[Hightower]

I am in the process of setting up a second network, which is completely separate from our main network. However, it would be nice to have my new network access to the internet for updates etc, but how would I go about doing this so the network doesn't conflict which each other?

How do you currently connect out?

How do you currently connect out?

 

We go through some kind of linux box that does everything for us, provided by the LEA with no access allowed to us (which is hosted internally - it's some kind of router/firewall etc).

[36Degrees]

Ask them if they have two separate IP ranges assigned for the school and if so what the details are. Although we do not have a separate admin network anymore the IP range still exists so the router has 2 distinct ranges and 2 default gateway addresses.

[glennda]

Ok I'm assuming you have a router on the other side of the linux box?

 

Ie. lea router - linux box - your old network

 

so you might be able to do this lea router - switch - linux box - your network and feed the new network into the switch before it goes to the router.

Seems you should first contact your lea and ask them if the nix box is configured for both networks (as 36Degrees said), and if not, can they. It shouldnt be a problem but if it is then you could configure your own proxy that sits between the lea nix box and your second network. This assumes that you want to use the lea proxy that is.

Ideally you should be using VLANs and L3 Routing to get your traffic from your new lan to your gateway.

 

Other options are:-

You simply designate a machine on your new network with two NICs to be a router to you main network.

 

just install a cheap cable router <£40 to be the default gateway for your new lan (Wan port on Router = an existing LAN ip address connected to your existing network, Lan Port on cable router an IP on your new lan with clients told to use this as the default gateway).

 

Create or use a free VM Appliance to be a router between the two lans using a Virtual Switch/NIC combination plenty of these available as Linux Live boxes using IP Cop etc...
