Jim Harrison <Jim@xxxxxxxxxxxx> wrote: http://www.ISAserver.org Your design is flawed. 1. all of the "company #" NICs can see the same router IP, so they're clearly in the same broadcast subnet 2. since they're all in the same BCST subnet, there is no gain in using separate NICs or even separate subnets, for that matter. 3. Since the subnets you chose are 10.1.x/24, Windows will not allow you to use a gateway outside the 10.1.x/24 subnet Basically, you have some reading to do: http://support.microsoft.com/default.aspx?scid=kb;en-us;164015 ------------------------------------------------------- Jim Harrison MCP(NT4, W2K), A+, Network+, PCG http://isaserver.org/Jim_Harrison/ http://isatools.org Read the help / books / articles! ------------------------------------------------------- -----Original Message----- From: hodakara kara [mailto:hatem20102011@xxxxxxxxx] Sent: Sunday, May 29, 2005 23:59 To: [ISAserver.org Discussion List] Subject: [isalist] ISA-Server 2000 With Multiple Network Card-Routing http://www.ISAserver.org Dear All, i am preparing My Company with other office as well to have Internet Connection. we Have here one Box, which installed on it Windows 2000 Advanced server , Routing & Remote Access server .
