Problems configuring NAT

[fleitao]

I need to configure a Cisco router model 3640 using NAT, as the description below:

All packets from one specific network must use the internet interface as inbound and outbound before reaching the target, at first it seems to be a not necessary hop, but I can’t change that.

This interface is the nat outside interface and I can’t change this configuration either.

Packets that have destination address 100.100.100.1, 100.100.100.2 or 100.100.100.3 must translate to the same destination, which is 10.6.1.15, after leaving ethernet interface.

I made use of NAT on a Stick, but I just got translate one to one, that is:

- 100.100.100.1 --> 10.6.1.15

or

- 100.100.100.2 --> 10.6.1.15

or

- 100.100.100.3 --> 10.6.1.15

Making use of static NAT I haven’t got, using dynamic NAT I haven’t got either.

Can someone help me?

Thanks in advance

Looks like you have Nat on a Stick configured properly since you are able to hit one of the static translations. This is more of a network design issue the way you describe your scenario. One other possibility would be to multihome the server and set up secondary network on the interface for the 100.100.100.1-3 addresses.
