[c-nsp] PIX: NAT inside a VPN?

[Garry]

Stupid question - couldn't find anything about this, and I don't think 
it will work, but ...

Is it possible to do a NAT on a PIX (7.0.x) inside a VPN? That is, 
remote network sets up a VPN to local Pix, but instead of using regular 
internal IPs, a NATted IP is used (in order to later possibly switch to 
a different server). Also, if, can an arbitrary IP be used?

 From what the admin gui will let me do, I don't think this is possible ...

Tnx, -gg
