Internet Only Router

Hello Team

I have a 2 sites each with a router. Site A connects to Site B via a Point to Point  T1. Site B uses this connection for everything including network mappings Internet etc.  Because of Utilization/slowness on the T1, Site B has decided to purchase a DSL Connection for Internet Only. So folks at Site B will use the T1 for all traffic except Internet which will be routed across the DSL Circuit.

I need Help recofiguring/configuring this to work with the above explanation :)  Please let me know if need to include the router configs for both site and what needs to be done Physically and logically to make this work...

Thanks in Advance

All you need to do is setup a default gateway pointing to the DSL modem. Add in route statements for your network traffic across the point2point.

Just a moment. We have a similar setup at one of our locations. I will grab you an example of what I mean.

You just need to point the site B folks to the new gateway of the DSL. If there's servers on the other side of the T1 you may need to add a route to all the windows machines with a login script or manually. Something like this:

//where 192.168.0.1 is the old gateway and 192.168.0.0 is the current subnet
Route -p add 192.168.0.0 mask 255.255.255.0 192.168.0.1

It may work just by adding both gateways to DHCP with the DSL being the first gateway

So in our case all of our internal networks are 192.168.x.x. We created the route statements to send everything except traffic destined for those networks out to the port out internet connection is on.

0.0.0.0 0.0.0.0 10.200.1.65 - Internet Connection
192.168.4.0 255.255.252.0 10.200.1.6 - Site2
192.168.16.0 255.255.252.0 10.200.1.6 - Site2
192.168.20.0 255.255.254.0 10.200.1.6 - Site2
192.168.24.0 255.255.254.0 10.200.1.6 - Site2
192.168.26.0 255.255.254.0 10.200.1.6 - Site2
192.168.28.0 255.255.252.0 10.200.1.6 - Site2
192.168.48.0 255.255.255.0 10.200.1.6 - Site2

Sounds good. This is for routes outbound.. what about traffic(Inbound) from the Internet? How do i control this from not going to the T1  traffic to get to Site B ?

Thanks

All of the traffic will pass in and out of the gateway the clients are using. If you're talking about server traffic it's a different story.

Traffic from the internet would not originate from your internal network ip ranges. So the traffic would be routed back out through you default gateway route, instead of across the T1 back to your network.

MY DSL cable modem would have a diff IP range from that of my Internal Lan(207.X.X.X). Do i need to NAT or Inform my Internet Provider of the IP range of my LAN ?

techzterCommented:
Are you able to manage the internal side of the router? The internal interface of you modem will need to have an ip in the same subnet of your network. So you will either need to change you lan setup to match the modem's internal configuration, or hopefully the modem's ip range can be changed.
