nat

[o.hassairi]

hello

i have the following scenario:

10.95.0.0--NAT router-------internet------------nat router---10.11.0.0

the 2 nat routers use dynamic nat with overload

ip nat inside source list 1 interface fastethernet overload.

we want to make a PC from 10.95.0.0 able to communicate with an other PC from 10.11.0.0 transparently.

is it possible using NAT ?

Yes, this is possible, presuming that the assigned Internet adress on both routers remains the same. Outgoing NAT with overload is not the problem, to direct the incoming traffic to the correct destination is. You have to define a static translation on both sides for this to make session-establishment from both sides possible. As you are using overload PAT you will have to assign a port number for this. To make specific applications work, you need to know at which port number they are attempting to connect.

Use the -ip nat inside source static- command to define this translations.
