IP Address Redirect

[dnorals]

Greetings,

I am moving to a new server for some vty session. I have more then 20 locations that connect to this server. We are moving to a new server within a couple of weeks. Each one of these sites is connected via 2801. Is there a wat for me to redirect this ip addrss X..X.X.X to this Ip address X.X.X.X from the router level.

Thanks In Advance

Best will be to setup a dns and use names instead of fixed IP's. This will create the possibility to migrate seamlessly to the new server. When you change the adress on the dns, all traffic will be redirected to the new server.

Deon,

If what Leo stated isn't feasible in your situation there is another way to do this, you can configure NAT to redirect traffic destined to the old IP to the new one.

Not sure how familiar you are with NAT configuration. The three pieces you need to configure are the nat inside interface, nat outside interface and a static NAT to redirect traffic to the new IP. In the static NAT config, in place of inside local address enter the new IP and in the gloabal IP option enter the old server IP.

Thanks for your replies.

Problem with changing the ip address is that the clients are setup with reflection on there desktop that is not using name per say. so that wouldnt work.

Also these remote sites are connected via frame - relay back to our corp router.

can you provide a sample command to do suggestion number two.

thanks

No problem. Here you go!!

interface f0/0

description connected to LAN

ip add 172.16.1.1 255.255.255.0

ip nat inside

int s0/0.1 point-to-point

description connected to Remote site

ip add 192.168.1.1 255.255.255.252

ip nat outside

Old IP of the server - 172.16.1.2

New IP of the server - 172.16.1.3

ip nat inside source static 172.16.1.3 172.16.1.2

Good Luck!!
