Setting up use of multiple gateways on a domain

Embriaguez · 09-08-2006, 10:28 AM

Hello there, thanks for spending your time reading this. This is my first post, so I hope it is correctly placed. I tried looking for info on this but I couldn't find anything, so here it goes.

I have a network with two internet access points. One of them is a DSL router (the default gateway currently used as the DHCP server commands) and a T1 line that is being used on a computer running Windows 2003 Server that has 2 network cards. One of those cards is directly connected to the internet, the other to the private network. The DHCP server is running in a Windows 2003 Server as well.

I understand that I can share the connection on the server with the T1 line and use it as a gateway - everyone will then use that connection.

What I need to do is: every access to the internet should use the current gateway (DSL router) EXCEPT for ips in a specific range. For those ips, the gateway used should be the computer with the T1 line; that computer will be sharing his connection.

As far as I understand, you can't have more than 1 gateway configured on the clients, so doing it only with DHCP would be out. I think that I would need to find a way to configure one of the W2003 machines as a gateway, and put in that machine rules that specify wich gateway it should use. It would be better for my network if it was the server with the T1 line, but it isn't required, I suppose.

So, am I on the right track? Is there a simple solution for this? Any help is greatly appreciated.

Thank you for your time.

There are a few ways to accomplish what you want to do. You can edit the local IPSec policy, you can enable a firewall with routing rules/port forwarding, you can set a proxy server, or you can set up Routing and Remote Access Server on your network. RRAS would be the recommended method, because you would be able to manage a host of clients from one policy. The RRAS would need to be your clients gateway and all traffic would be filtered from there. Learn More

Hello,

Just wanted to thank you, after doing some research I managed to solve it easily using RRAS and setting a default route.
