Change destination address

I would know: It would be possible to implement in a Catalyst 6500, when a packet reaches with destination IP address is redirected to IP (are servers)
Is that possible making some kind of NAT ?




Re: Change destination address

Hello ,

As much as i know you can change source ip address with NAT, If you want to redirect all traffic to some IP

you can take help from PBR

like you can prepare route-map

ip access-list extended 101

match ip any

route-map REDIRECT permit 10

match ip address 101

set ip next-hop

Hope this helps

Re: Change destination address

Dear Mahesh , Don't you think that using the " Match Access List +  Route Map & Set IP Next Hop " Configuration will only Redirect the Traffic to , But at the end the Packet Destination IP Address still contains the old IP Address " " . I think when the Traffic get Matched over the Access List and Redirected by the Route Map , it will be Dropped off when it reaches the Host ...What do you think ??


Re: Change destination address


Not sure what you want to achieve whether you want an outside host with ip x.x.x to appear as y.y.y.y to the inside?

If so you need to configure outside NAT.

Please take a look at this link:

Hope it helps, rate if does

Re: Change destination address

No, actually I want to change the data with destination address will be redirected to, are two hosts on the same network.

The simplest would be to change the IP of the end host, but the customer does not want.


Re: Change destination address


There is a function called SLB ( server load balancing ) that You can investigate. It might be what You are looking for.

here are 2 links to start with.

Re: Change destination address

No. We have ruled out this option and we  will change the addresses of the destination machine.

Thank you.

Re: Change destination address


If I undertand you correctly I think you area looking for something called destination nat.

Something in the line of.

access-list 100 permit ip any host


ip nat pool DESTNAT prefix-length 24  !not sure exactly what mask to use.

ip nat inside destination list 100 pool DESTNET

I would have prefered to use a static instead of pool but it appears to have been removed from later versions of IOS.
