DearExperts,
We are facing natting issue in my setup which is enclosed with this thread.
actually 172.17.64.202 server should talk to 10.16.2.245.
We ahve configured necessary routes on R1 fro 172.17.64.X and EIGRP is configured for 10.0.0.0 . On R1 static rouets to R2 is redistributed.
we are able to ping to 172.17.64.202 from 10.16.2.245.
But 10.16.2.245 applications can be accessed only if request comes fromsame subnet i.e 10.16.2.x subent.
we need to do natting for 172.17.64.202 so that it could be translated to 10.16.2.x ip which inturn talks to 10.16.2.245.
where to do the natting i mean on which router.
any help would be appreciated.
Thanks,
Satish

This does not sound like a Natting issue but an Access-list issue. If you can Ping the remote machines from each other then IP connectivity is established. However if Applications are not functioning correctly. make sure that you have no Access-lists in between these machines that are denying application ports or certain TCP or UDP traffic either dedicated to these IPs or subnets ....

Thanks for your reply..
Main thing is 10.16.2.245 server willn't allow other ip's from differnet subnet to access it's applications.
172.x.x.202 server should access 10.16.2.245 server.
To access 10.16.2.245 from 172.x.x.202 , 172.x.x.202 should ne converted into 10.16.2.x series using NAT so that 172.x.x.202 can access 10.16.2.245..
ANy idea

So from what I can gather if the server only serves to devices in the 10.16.2.x subnet then you can apply Natting to the first layer 3 device (4006 with Layer 3 module). Do a static nat allowing the 172.17.64.202 device to translate to a 10.16.2.x address. This way whenever the 10.16.2.x server initiates a session it will be translated to a 172.17.64.xx IP and the remote server should answer to it....

Hi ,
Thanks for your info and reply.
Actually , 4006 L3 IOS is not supporting natting.
So is there any alretnative other than loading IOS on L# which supports NAtting..
I mean on Routers can we do Natting..I've done natting on routers but 172.x.x.x is not at all communicating to 10.16.x.x after translation.
Thanks,
Satish
