Does anyone know how I would configure a 17x1 router, 18x1 router, or pix to perform a destination IP rewrite?
For example if host 126.96.36.199 is sending a packet to 188.8.131.52, I want to rewrite 184.108.40.206 to 220.127.116.11 . Changing the destination IP in the application is not currently possible so I want to rewrite it in transit.
The NAT commands I've looked at all appear to modify source ip addresses only, not destination. Outside NAT on the pix does not seem to do what I need either.
Thank you for the reply. This doesn't seem to do exactly what I have in mind. Let me try to clarify:
1. I actually have multiple source hosts talking to one specific destination IP address.
2. I want to configure the router or pix so that one specific source host talks to a different destination IP address without touching the source host.
3. All hosts go to the same router on the other end of the link over which I have no control.
So I need to rewrite the destination IP address inside the packet without mofidying the source host. Based on the example at the link provided above it would seem that I need to configure routers on both ends of the link, but I cannot do that.
I think DNAT with netfilter or ipchains in Linux can accomplish what I am trying to do, but adding another box is not an option. Adding another Cisco device might be.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does

Attached policy provides CLI access to the Cisco 4G router over text messaging. Two files are in the attached .tar file:
