Multiple gateways windows

There can be only one Default Gateway. I've checked this situation and can now confirm that Windows not or not always sends traffic to route with lower metric. Next time I will check twice before answering — kallax. Teamwork in action. In Windows, it is a total misconfiguration and causes much grief.

This switch can occur when there are multiple gateways configured for the same network adapter or when different default gateway addresses are given on various network cards on a multihomed computer. A switch is triggered when TCP has tried one-half of the TcpMaxDataRetransmissions times to send a packet through the current default gateway.

After the switch, all IP traffic originating from any network adapter on this computer destined for remote networks will be sent to the currently selected gateway. On disjointed networks, this can lead to lost connectivity and subsequent termination of active sessions with computers on remote networks connected through the first gateway.

This is because the currently selected gateway may be unaware of other routes managed by the first gateway if those routers do not exchange routing information to each other. If the switched gateway is unreachable or inactive on the network, it loses connectivity to all remote sites.

At this point, a ping to this computer from a remote network will fail to get a positive response. Similarly, any outgoing ping to a remote host from this computer will give a Request timed out error. Consider a computer with two network cards, Netcard1 and Netcard2, and the following IP addresses and default gateways:. Netcard1: IP Address: If you want to Telnet to a workstation with an IP address of Finding no direct connected interface, the PC will look in the route table for a match.

But 8. I knew there was a static route command, just never had occasion to use it until today. So were you saying adding the static route command should preclude needing to add a gateway IP on the second NIC? I'm familiar with the static router command, just never had occasion to use it until today. So were you saying adding the static router command should preclude needing to add a gateway IP on the second NIC?

Thanks a lot, Rob! We'll give it a go and see how it turns out. And that taught or refreshed me a little more on how Windows handles routing. To continue this discussion, please ask a new question. Laplink Software, Inc. Neil Laplink.
