Not that I'm advocating it, but whether or not it could be done depends. >From a high level, you could define some static network address translations (NAT) that map your old address to your new addresses.
The depends part comes now, your router would need to be positioned such that the old addresses would be routed to it. And I believe the second interface would need to be on a separate subnet. NAT requires an inside and an outside interface and those interface need to be on separate subnets. Better solutions.. Adjust the TTL on the DNS records for the web servers to stop DNS records from being cached. Then change the DNS record during the move. Sound like you don't like that option. How about leaving a reverse-proxy or just a http server with a redirect at the old ip address for some time. -----Original Message----- From: Trevor Jennings [mailto:[EMAIL PROTECTED]] Sent: Monday, April 22, 2002 9:16 AM To: [EMAIL PROTECTED] Subject: OT: Using a Router to redirect IP traffic [7:42217] Hello, Where I work, we have a number of servers being co-located at one location and are planning on moving those servers to another co-location provider soon. My boss asked me why we could not, when we move the servers, just place a router at the original ISP to redirect all traffic from the original ip's to the new ip's rather than having duplicate servers or adjusting the DNS at the same time. I told him that I wasnt sure whether it was possible and was told by a friend that its not really possible to do that. Can anyone confirm that or rather explain why that is not possible? My Boss's theory was that we would have a router with 2 ethernet ports and redirect the original ip's to the new ip's through the second ethernet.
