quick explanation of the situation.
2003 server 1 Nic.
2 internet feeds
what i want to do is have the server attempt network traffic over the first feed and if it is unable to reach the destination then it will try across the 2nd feed.
My thinking on this is that if i add two gateways to the NIC with a lower metric on the first then that should work as per http://wiki.answers.com/Q/What_is_Gateway_and_Metric
My understanding is that the metric is basically a cost on the connection, so do i simply set them as 1 and 2 or do i need to set them as say 1 and 10000 as i am not sure if the cost is simply added to the total cost of the route.
Eg if browse to google
cost of metric = 1
cost of route = 50
Total cost = 51
cost of metric = 2
cost of route = 30
Total cost = 32
So in this instance as gateway 2 can get to the site quicker it will have a lower total cost and therefore will allways get used in preferance to gateway 1. But if i set the gateway 2 metric to 1000 then the total cost on the route for gateway2 would be 1030 which is higher.
Can anyone shed some light on this for me.
