Sharing leased line

[CAWJames]

Evening all,

 

We operate a remote teaching centre within another businesses premises.

 

We have been slowly going up the internet ladder, dial-up then broadband, now a bonded ADSL solution.

 

The bonded solution has been a nightmare as we are on the end of the line, and frequently get stale sessions and lines dropping out.

 

We have now decided to go leased line, but want to share the bandwidth and cost with the 'host' business.

 

BT will supply the line, NTE and a Cisco router, which in the normal world would connect into a single router and provide the magic to the LAN.

 

We want to split the output from the Cisco to our SonicWall and to the host business's Firebox, giving each a public IP and access to the other Public IP's available for websites, VPN etc.

 

Now for the question:

 

Is it as easy as putting a switch in between the Cisco and the 2 firewalls? One wire from Cisco to switch, one wire to each router? Then setting each one up with its own IP and shared gateway.

 

In my head it's that easy, but I am frequently wrong! We don't mind about proportioning bandwidth or anything like that, we just want to segregate and give each business its own access to public IP's and ease of VPN.

 

Any help would be appreciated

 

Thanks

YEP! - assuming you have a couple of Public IP's

You might be better off getting a wires only service. If you supply the router you could vlan the 2 networks and provide a service so that each party receives a proportional amount of bandwidth to which they pay.

Thanks for the amazingly quick replies!

 

James, Depends on the RIPE, my favourite thing to fill in! But yes we will probably get a small pool of IP's with the line depending on how many the host business need. As long as we can use 2 of them to give to the routers, all will be good

 

I thought it was going to be that easy, but our BT manager started talking about multiplexers and packateers, which I thought would be overkill

 

CyberNerd, We dont care too much about proportioning bandwidth, we just want to be able to use our existing equipment and keep our LAN's/setups as they are, just more and better bandwidth. They are a pet shop and boarding business, we are a college, neither with high bandwidth needs. Mostly net and VPN to our respective HQ's.

 

Thanks
