Geert,
if you think of having two subnets with the same address and netmask
parted by one router you'll get problems. Either you'll have to take
an extra router with a different subnet address between the routers
or you'll have to take another address/netmask combination.

Example:
testnet 10.0.2.0/22 --- 10.0.0.1 router v.x.y.z --- v.x.y.t router
10.0.2.0/22 --- production net
The additional router may be any computer of the production net with
an extra NIC configured to v.x.y.t and NAT.
The doubling of masquerading in the two routers can be accepted for
testing.

In this combination, neither the testing net nor the production net
is visible from the other side and they don't disturb another.
