I have one physical network adapter, I want my machine to reside on two different subnets from the same ethernet cable. Subnet 1: 192.168.52.10 default gw 192.168.52.1 Subnet 2: 192.168.90.10 default gw 192.168.90.1 All traffic that is not FROM 192.168.90.10 would use the x.x.52.x network and default gateway Traffic from the 192.168.90.10 ip address would be routed to 192.168.90.1 How can I setup a Windows 7 machine to do that? Thanks!

It appears that you already have another thread with the same topic: http://social.technet.microsoft.com/Forums/en-US/w7itpronetworking/thread/e7141260-df93-4781-8367-dc28fe276302 It would probalby be best if only one topic is used so that the responses stay in the same thread, unless these two threads are not related. In any case, this design is not supported by Windows out of the box. While I know that there is 3rd party software (generally for servers) that will allow a NIC to allow VLAN tagging to the NIC, I don't know of such software for a Windows 7 system. Visit: anITKB.com, an IT Knowledge Base.

It is all about the routing you can use the route function in windows the same way you do in linux. The syntax of the command is diffrent but the end result is the same ROUTE ADD 192.168.90.0 255.255.255.0 192.168.90.1 -p with this 192.168.90.0 is the destination that you are adding. 255.255.255.0 would be the subnet mask for the destination, and 192.168.90.1 would be the gateway address. and yes you can bind more than one IP address / GW to the single nic under the properties for TCP 4 (the advanced tab).

I was told to re-post here.

Thanks, unfortunately it still wants to route traffic from that program using the alternate subnet out of the primary default gateway (highest metric). That's why I need to have a second interface (an alias of the primary physical interface) but which will be seen to routing as a second internet interface. In linux, an eth0:0 is seen as a separate physical interface and you can route traffic out of that interface specifically which would use its default gateway (rather than any default gateway bound to another interface). I'm trying to find out how to alias a physical interface in Windows to deal with this issue. Thanks!

Hi, I found there is a duplicate thread http://social.technet.microsoft.com/Forums/en-US/w7itpronetworking/thread/e7141260-df93-4781-8367-dc28fe276302 In order to avoid confusion and keep track of troubleshooting steps, I recommend you keep working with the original one in this issue.
