Two internet connections on a single server

Hi all,

We have a Windows 2003 server standard edition that is used for remote
access. It has an ADSL connection and an SDSL connection, the lines are
provided by separate ISPs and both internet connections use individual 3com
network adapters and routers.

The problem is:
in order for the internet connections to function we have to point each
network adapters default gateway to it's specific router.

This is a problem as I don't think you can have two Default Gateways, and
when I do a "Route Print" at the command prompt I can see that windows is
switching between the two routers as it's Default Gateway.

When this happens we can't use the SDSL connection until we disable the ADSL
connection.

How do I have two internet connections on the same computer without running
in to this Default Gateway conflict?

Regards,

Mike.

Hi Mike,

One option would be to implement ISA server with Rainfinity plug-in. Here
are the details...

Thanks for the reply Miha.

That software looks good I am sure we are going to test this.

Is there a method of configuring this without getting ISA server or 3rd
party software?

Mike.

Cetainly, you can use a hardware device to aggragate the lines.
One such device is the FireBrick

Hi all,

Would it be OK if I did the folowing, have one default gateway for one of
the connections in the Network control panel and add a second gateway with
higher cost / metric using route.exe?

here is something like what I have in mind:

------------------------------------------------------------------------------------

Remove the current gateways for a fresh start:

Route.exe delete 0.0.0.0

Add a default Gateway for the other connection in the TCP/IP setting page of
the adapter leave all other gateway information blank and then:

REM : add a new gateway with a higher metric this is the second gateway .

REM any IP - on any Network - routers address - metric / cost - switch to
make it stay after reboot.

Route add 0.0.0.0 mask 0.0.0.0 192.168.0.1 metric 40 -P

---------------------------------------------------------------------------------------

can any see big problems with this

Regards,



MM.
