I did something similiar just this month. The way I did it was to setup
their new router that connected them with us with NAT. I assigned them a new
private range (say 172.16.1.x /24 ). Then used NAT overload so that all
traffic coming from them looked like it was from the 172.16.1.3 address that
was used as the overload. Then so we could access the servers that we needed
on their network I just added some static NAT entries with addresses like
172.16.1.5 and above. It works fine in the interm until we actually convert
them to be in a range we arent using.

Hope that helps some

Tim

Our routers can't determine if the traffic is local or remote.  So traffic
destine for the new company is never sent because the routers believe it's
locale.  I don't see how NAT would help.

I've never done this myself...
But I do not see a reason why you cannot use NAT overloading to do the
job....
10.10.10.x<------->Real IP<===============>Real IP <----------> 10.10.10.x

Please correct me if I am wrong....
