Simple static Natting on my ASA5510

Hi guys,

I'm just starting into our Cisco ASA for a bit of playing.. and now I've come to the following 'issue'.

It's probably not that hard.. but.. I still need ya help .

We are going to setup a VPN tunnel between 2 companies.

I would like to NAT some addresses for the servers contacted in our company.

So, the client would access virtual ip address : 10.31.251.1 over the vpn which is on our internal side, but actually the 10.31.251.1 is the 10.5.7.22

so this would mean :

Client will try to connect to 10.31.251.1 over the VPN.
Our cisco ASA box will accept this connection and will spit it onto our internal network, but instead of 10.31.251.1 it will spit 10.5.7.22

Before trying and playing with our config I just wanted to double check my idea.

for this I had something in mind as

-setup the vpn (not a problem)
-nat the address (thats the 'problem')

Would it be something as :

static (InternalNetwork,InternalNetwork) 10.31.251.1 10.5.7.22 netmask 255.255.255.255

?
Thanks for ur help
