Regarding IDU connectivity.

Specs: Windows XP
I have two IDU's for VSAT connectivity, one is for primary and another one will be used as a backup link if first one will unavilable. Both IDU's are connected directly to switch and user are also connected to same switch.
I am facing the problem is that when my one IDU get down, users of the Lan segment has to change their Default gateway. So what can i do to solve this issue.

Thanks,

I suspect a "dual WAN router" may be what you're looking for. Research several in-depth to see if they can do what you need.

It is possible with a computer but I wouldn't expect to be able to do it with a Windows box.

What you're talking about is fairly complex. You have to have two external interfaces. The active one has to be monitored at all times. Should the connection fail, it has to change over to the other connection automatically.

I know it can be done with UNIX. We use dual teamed OpenBSD servers for our firewalls/routers that provide just this type of fail over. They utilize VRRP techonology so they both operate on one gateway IP address.

In order to do this, you'd need to be very familiar with UNIX and VRRP. If you're not that fluent in UNIX, then the simple solution would be a dual WAN router that does this for you. Which is why I suggested that at the outset.
