View Full Version : NAT Internet Connection Keeps Going Down

We've got network address translation running on our Windows 2003 server. We've got 7 workstation computers on the network.

NAT has been sharing our broadband ADSL internet connection for about a month and has been working perfectly. Each computer can access the internet from their workstation via the server.


Here's our problem:

At various times during the day (about 4 times a day) our internet access goes down. No workstations can view and web pages nor can the server.

To get it back online again we have to disable the internal network interface and then re-enable it. It only takes a couple of seconds to do so but it's beginning to be a real pain. There are no errors in Event Viewer and we've confirmed it's not a problem with our ISP.

Routing and remote access does not give any visible errors about anything being down or offline but it does seem as though the problem is being caused somewhere near to where NAT passes the internal network traffic onto the external internet interface.


Any help on this would be greatly appreciated.

I was wondering if you found a solution to your problem? I have a NAT running on Win2K server, but the XP computers with SP 2 behind it are having issues. They can't seem to download anything from the internet faster than about 200-300 B/s (yes that's right, about 10% of dial up). I don't suppose you have run into this problem. All of the other computers on my network run just fine, its just the XP SP2 computers.
