I haven't had to do it personally, but it looks pretty easy...

> Normal uni-directional NAT will hide an address (change the
> source and/or
> destination addresses) in one direction only. Bi-directional
> will change it
> in both directions. Picture a network like below:
>
> Host A-----Router----Host B
> with Host A on the 'nat inside' interface, and B on the
> 'nat outside'
> interface.
>
> If Host A has a configured inside static nat, it can be
> reached from host B
> via an address held by the router. These packets reaching A
> will have host
> B's real source address. A will respond to B's real address.
> But if you wanted bi-directional nat, you'd configure a
> static or
> pool for the outside also, so that when B sends to A, B's
> source address is
> changed at the router, so that both the source and the
> destination address
> change for any given packet. A sees B as a fictitious
> address held by the
> router, and B sees A as the same.
> Bi-directional NAT is most useful for connecting 2
> networks where the
> address spaces have some duplication. HTH.
