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

Situation:

server-1 (212.123.200.1) on fa0/1

server-2 (192.168.10.101) 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 192.168.10.101 212.123.200.101

That works for the outside.

server-1 can access server-2 by connecting to ip address 212.123.200.101.

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 212.123.200.1, but ip address 192.168.10.111.

So 212.123.200.1 should be translated to 192.168.10.111.

In an ASA it is very simple by just using:

nat (inside,outside) 212.123.200.101 192.168.10.101

and

nat (outside,inside) 192.168.10.111 212.123.200.1

But how is this being done in a router?
