|I suppose you could try giving the particular client dual NIC's one configured for, and plugged into, each subnet. Then they would need to enable the one they want to use and disable the other. |
I have 3 NIC's in my one PC here in my office. One connects to the subnet I'm on normally, the second I use for configuring switches and routers and such and the third connects to our management subnet.
When I'm doing normal day-to-day stuff I leave NIC 1 enabled and 2 and 3 are disabled (in My Network Places). When I need to configure a switch, I disable 1 and enable 2. IfI need to go on the mangaement subnet, I disable 1 or 2 (whichever I'm using at the time) and enable 3...etc etc
As far as I know, there's no automatic way to do this so nobody has to change anything. You can't for instance have both NIC's configured for separate subnets and have both enabled and have traffic go where you want it to as there's no way to (internally, within the computer) tell the traffic to use a specific interface.
It only takes about 5 seconds to right click on My Network Places, choose "Properties" then right click on the NIC you're using and select "disable" then right click on the one you wish to use and click on "enable" and the user could be shown how to do this in about 1 minute.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
