dual static nat translations

Unanswered Question
Feb 6th, 2008

I am looking for a solution to use static nat translation on both sides of a router (not an ASA/PIX).


server-1 ( on fa0/1

server-2 ( on fa0/0

fa0/0 = ip nat inside

fa0/1 = ip nat outside

To translate server-2 on outside I use:

ip nat inside source static

That works for the outside.

server-1 can access server-2 by connecting to ip address

But I want to do this exactly the same for the inside.

So i would like to be able to connect from server-2 to server-1, not by accessing the ip address, but ip address

So should be translated to

In an ASA it is very simple by just using:

nat (inside,outside)


nat (outside,inside)

But how is this being done in a router?

I have this problem too.

You need to do a source and destination NAT translation on the same device. You need to create a /32 route pointing to the FA0/0 interface. This is going to be VERY cludgy design and is not recommended.
