Media for IOS and destination NAT

IOS and destination NAT

Hello.

Here is a brief description of my problem:

I am trying to do destination-NAT using a cisco-router running IOS

12.2(15)T2

Interfaces: Interface FastEthernet0/1: public IP / ip nat outside

Interface FastEthernet0/0.1-0.X: public IPs / no nat

Interface Tunnel0: private IP - connection to private ip-networks / ip nat inside

At the moment the device is using NAT (SNAT) for the private IP-networks: ip nat inside source list NATList interface FastEthernet0/1 overload ip access-list extended NATList permit ip 10.0.0.0 0.0.0.255 any

permit ip 10.0.1.0 0.0.0.255 any

permit ip 192.168.2.0 0.0.0.255 any

permit ip 192.168.5.0 0.0.0.255 any

permit ip 172.8.0.0 0.0.0.255 any

... !

In addition I like to configuer now a Destination-NAT for some IPs connected at the moment via Fa0/0.Y to be forwarded somewhere into the private IP-Space, lets say: all traffic targeting public.ip.dnat.1 has to be forwarded to

192.168.2.11 and all traffic originating from 192.168.2.11 has to be NATed to public.ip.dnat.1.

I tried a lot - but gave me no usable results (for my understanding I need something like 'ip nat outside destination static ....' but ... you know thats not there ;-) I can do something like portforwarding - but no complete redirection

Maybe someone of you can help me untie the gordian knot in the head of a poor autodidact.

Thank you Best regards Klaus
